NOTICE

Due to a preliminary finding by a federal court in the United States, Shure is authorized to ship the MXA910-60CM. This model is fully certified and lawful to use anywhere in the world but is not lawful to be used in the United States in a drop ceiling mounting configuration such as shown below. It is also unlawful to use adapters in an attempt to fit this smaller version to a ceiling grid within the United States such that it mounts substantially as shown below.

Furthermore, the MXA910-60CM is not designed or intended to be installed within a 24” ceiling grid, which is the standard size grid in North America. Mounting in such a grid in the above-shown configuration is unsafe and may cause damage to the product and/or injury to those below. The MXA910-60CM is safe and lawful for use in other mounting configurations, such as with hard ceilings, or suspended from a VESA pole or suspension wiring, anywhere in the world.

A new version of the MXA910 for 24” ceiling grid installations in the United States is now available for pre-order, with delivery expected in December 2019. The MXA910W-A provides a quick, simple solution for installation in 24x24 inch ceiling grids in the U.S. and includes the same technology and performance as all prior versions.

System Overview

① Dante audio, power, and control

Each array microphone connects to the network over a single network cable, which carries Dante audio, Power over Ethernet (PoE), and control information to adjust coverage, audio levels, and processing.

② Analog audio (microphone to network)

Analog equipment, such as a wireless microphone system or a gooseneck microphone on a podium, connects to the Dante audio network through a Shure Network Interface (model ANI4IN) for a completely networked conferencing system.

③ Far-end audio (network to loudspeakers)

Dante-enabled loudspeakers and amplifiers connect directly to a network switch. Analog loudspeakers and amplifiers connect through a Shure Network Interface (model ANI4OUT), which converts Dante audio channels into analog signals, delivered through 4 discrete XLR or block connector outputs.

④ Device control and Dante audio

Control: A computer connected to the network controls the microphone with Shure Designer software. You can remotely adjust coverage, muting, LED behavior, lobe settings, gain, and network settings.

Audio: Route audio with Dante™ Controller or Shure Designer software. Dante Virtual Soundcard enables audio monitoring and recording directly on the computer.

Differences Between 3.x and 4.x Firmware

When you update an MXA910 from 3.x to 4.x firmware, you'll be able to use IntelliMix DSP features optimized for MXA.

Here's what changes with 4.x firmware:

IntelliMix DSP Added

  • You can now use AGC, AEC, noise reduction, compressor, and delay.
    • These DSP features don’t affect individual channel outputs—they only apply to the Automix Out channel
  • If you’re currently using the Automix Out channel on a 3.x device and you update it to 4.x, the following settings will be applied automatically:
    • AGC: enabled
    • AEC: enabled
    • Noise reduction: enabled
    • Compressor: disabled
    • Delay: disabled

New Automixer Added

  • The 4.x automixer has different mix modes than the 3.x automixer.
  • Here's how mix mode settings will change:
    3.x Automixer Setting New 4.x Automixer Setting
    Classic Gating
    Smooth Gain Sharing
    Manual Manual
    Custom Gating

New Autofocus Feature Added for All Lobes

  • Patent-pending Autofocus™ technology continually fine-tunes the position of each lobe in real time.
  • Lobes move automatically for consistent sound when participants lean back in their chairs or stand up.

Echo Reduction Removed

  • The microphone now has AEC, so there's no need for echo reduction.
  • The Echo Reduction Reference In channel's name in Dante Controller is now the "AEC Reference In" channel. Any existing Dante route to that channel will persist.

Other Changes

  • Template 1's lobe positions have changed.
    • If you're using Template 1 with the default lobe positions, updating to 4.x will change your lobe positions.
  • After updating, all custom lobe positions and Dante routes will stay the same.

Installation

Microphone Placement

Room Variables

Optimal microphone placement is determined by the seating arrangements and infrastructure. Follow these guidelines for the best possible results:

  • In rooms with flexible furniture arrangements or multiple array microphones, use the microphone configuration tool in the web application or Shure Designer software to ensure that the coverage is adequate for all seating scenarios.
  • The lobes should be pointed towards the front of each talker. Carefully consider placement in rooms where talkers may face a screen during a video conference.
  • Avoid installing the microphone directly next to unwanted sound sources, such as air vents or noisy video projectors.
  • Consider installing acoustic treatment to improve speech intelligibility in rooms that are too reverberant.

Mounting Height

The maximum mounting height that can be set is 30 feet (9.14 meters). In a typical acoustic environment1, the microphone maintains an "A" rating based on the STIPA2 (Speech Transmission Index for Public Address systems) international standard at distances up to 16 feet between the microphone and talker. In better acoustic environments, the STIPA "A" rating may extend beyond 16 feet.

Consider the following when determining a mounting height:

  • The pickup pattern of the ceiling array is narrower than a shotgun microphone, and therefore it can be placed farther from the source than any other microphone. While the web application shows an ideal coverage zone for each channel, keep in mind that there is no specific barrier at which the audio degrades or gates off. Lobe sensitivity data is available for each width setting in the product specifications.
  • Like all microphones, tonality changes as the distance from the source increases.
  • The intelligibility scale helps to predict how the microphone will sound at a given height.
  • The coverage area of the lobes increases at farther distances.

[1] Room conditions: RT60 (reverb time) = 500 ms @ 1kHz, A weighted room noise = 40dBSPL(A)

[2] IEC-602682-16 standard

Intelligibility Scale

The intelligibility scale objectively compares the acoustic performance of the array microphone with a cardioid gooseneck microphone at various distances. This information is useful for predicting how the array microphone will perform at a given distance and to determine an ideal mounting height. The data in the intelligibility scale table is derived from measuring the microphones to meet an equivalent value from the Speech Transmission Index IEC-602682-16 standard.

Distances With Equivalent Speech Transmission Index Values

Ceiling Array Microphone (Distance to Talker) Cardioid Gooseneck Microphone (Distance to Talker)
6 ft (1.83 m) 3.75 feet (1.14 m)
8 ft (2.44 m) 5 feet (1.52 m)
10 ft (3.05 m) 6.25 feet (1.91 m)
12 ft (3.66 m) 7.5 feet (2.29 m)

Data was collected in a typical huddle room with the following measurements:

  • Reverberation decay time: 500 ms @ 1kHz
  • Noise floor: 40 dB SPL (A-weighted)

Note: These values are specific to the described room. In a well-controlled acoustic environment, the array microphone may perform with equivalent Speech Transmission Index values at even greater distances. In highly reverberant rooms, the performance is less predictable.

A = Distance between array microphone and talker

B = Distance between cardioid microphone and talker

In this example, the acoustic performance of the array microphone mounted (A) feet from the talker matches the cardioid gooseneck microphone placed at a distance of (B) feet from the talker.

FyreWrap® Fire Protective Wrap System Installation

The FyreWrap fire protective wrap system included with the MicroflexAdvance MXA910 ceiling array microphone must be installed to meet the UL 2043 plenum rating (suitable for air handling spaces).

Firmware Release Requirements

All devices comprise a network with multiple communications protocols that work together to ensure proper operation. The recommended best practice is that all devices are on an identical release. To view the firmware version of each device on the network, open the component user interface, and look under Settings > About.

The format for Shure device’s firmware is MAJOR.MINOR.PATCH. (Ex. 1.6.2 where 1 is the Major firmware level, 6 is the Minor firmware level, and 2 is the Patch firmware level.) At minimum, devices that operate on the same subnet should have identical MAJOR and MINOR release numbers.

  • Devices of different MAJOR releases are not compatible.
  • Differences in the PATCH firmware release level may introduce undesired inconsistencies.

Microphone Configuration

Software Overview

Designer allows administrators and technicians to control:

Coverage: Adjust lobe width and location, select templates, save or load presets, customize light bar settings, and run automatic setup.

Channels: Adjust and monitor channel levels, mute channels or channel groups, configure automix settings, and adjust equalizer settings.

Settings: Control network IP settings, device name, passwords, languages, firmware identification, and device reset.

Software Workflow Basics

Think of each lobe as an individual microphone. If there were 8 microphones on the table, each one could be physically moved according to seating arrangements, and would be plugged into a mixer with independent gain and channel controls. With the Microflex Advance Ceiling Array Microphone, Designer delivers control over the physical coverage and audio channel settings, with user presets to quickly switch between configurations. Each lobe is moved according to seating arrangements, with three width settings to change the size of the coverage area. Independent mixer channels control the level and audio properties for each lobe.

Each lobe is represented graphically and can be dragged into place. A corresponding mixer channel provides control over audio settings for each lobe.

Configuring Microphone Coverage for MXA910

To configure the MXA910, follow these steps:

Set Device Properties

Select the device and set the properties:

  1. Enter a value for the device height (the distance between the floor and the microphone). By default, the device height matches the ceiling height, though you can adjust them independently.
  2. Move and rotate the device to match your layout.

Position Microphone Coverage

  1. Add channels by clicking Add channel above the workspace.
  2. Enter the talker height by selecting a channel and providing the value in the Properties. This ensures accurate aiming.
  3. Move channels to cover the appropriate areas:
    • Channels are independently selectable and can be moved anywhere within the maximum allowed coverage area. If dragged outside of this region, lobes turn red and revert back to the last acceptable position.
    • Position the channels by dragging or nudging them into place. Distance values to the device and to the workspace 0,0 are calculated in the properties panel.
    • Use the grid to measure the precise placement.

Adjust Channel Width

Independent width control makes it possible for some channels to capture individual talkers (narrow), while others cover multiple talkers (wide).

To change a channel width:

  1. Select the channel
  2. Choose a width setting from the pull-down menu. The width is calculated and displayed, based on the lobe location and heights entered for the device and talker.

Width Settings:

  • Narrow (35°)
  • Medium (45°)
  • Wide (55°)

Channel widths for the three settings with the microphone 6 feet above a table

Use Auto position

You can use Auto position to correctly position the lobe for a selected channel:

  1. Select a channel.
  2. Click Auto position.
  3. Ensure that you have the correct channel selected and the talker height specified.
  4. Click Listen. Designer listens and determines the correct position and width for the channel.
  5. A confirmation dialog displays when Designer determines the correct position and width.

Adjusting Levels

Gain levels on MicroflexAdvance microphones must be set for each saved coverage preset to ensure an optimized gain structure for all seating scenarios. Always adjust the levels before making any changes to automix settings to ensure the best performance.

  1. Perform a level check for each coverage area, using a typical speech volume. Adjust the faders so the meters are peaking at approximately -20 dBFS.
  2. Adjust the equalizer settings to optimize speech intelligibility and minimize noise (such as low-frequency rumble caused by HVAC systems).
  3. If equalizer settings cause a significant increase or decrease in levels, make any necessary level adjustments according to step 1.

When to Use the Channel and IntelliMix Gain Faders

There are 2 different gain faders that serve different purposes:

Channel Gain (Pre-Gate)

To adjust, go to Channels. These faders affect a channel's gain before it reaches the automixer and therefore affect the automixer's gating decision. Boosting the gain here will make the lobe more sensitive to sound sources and more likely to gate on. Lowering gain here makes the lobe less sensitive and less likely to gate on. If you're only using direct outputs for each channel without the automixer, you only need to use these faders.

IntelliMix Gain (Post-Gate)

To adjust, go to Configuration > IntelliMix. These faders adjust a channel's gain after the lobe has gated on. Adjusting the gain here will not affect the automixer's gating decision. Only use these faders to adjust the gain of a talker after you are satisfied with the automixer's gating behavior.

Parametric Equalizer (PEQ)

Maximize audio quality by adjusting the frequency response with the parametric equalizer.

Common equalizer applications:

  • Improve speech intelligibility
  • Reduce noise from HVAC systems or video projectors
  • Reduce room irregularities
  • Adjust frequency response for reinforcement systems

To turn off all EQ filters, select Bypass all EQ.

If you’re using Shure Designer software to configure your system, please check the Designer help section for more about this topic.

Setting Filter Parameters

Adjust filter settings by manipulating the icons in the frequency response graph, or by entering numeric values. Disable a filter using the check-box next to the filter.

Filter Type

Only the first and last band have selectable filter types.

Parametric: Attenuates or boosts the signal within a customizable frequency range

Low Cut: Rolls off the audio signal below the selected frequency

Low Shelf: Attenuates or boosts the audio signal below the selected frequency

High Cut: Rolls off the audio signal above the selected frequency

High Shelf: Attenuates or boosts the audio signal above the selected frequency

Frequency

Select the center frequency of the filter to cut/boost

Gain

Adjusts the level for a specific filter (+/- 30 dB)

Q

Adjusts the range of frequencies affected by the filter. As this value increases, the bandwidth becomes thinner.

Width

Adjusts the range of frequencies affected by the filter. The value is represented in octaves.

Note: The Q and width parameters affect the equalization curve in the same way. The only difference is the way the values are represented.

Copy, Paste, Import, and Export Equalizer Channel Settings

These features make it simple to use effective equalizer settings from a previous installation, or simply accelerate configuration time.

Copy and Paste

Use to quickly apply the same PEQ setting across multiple channels.

  1. Select the channel from the pull-down menu in the PEQ screen.
  2. Select Copy
  3. In the pull-down menu, select the channel to apply the PEQ setting and select Paste.

Import and Export

Use to save and load PEQ settings from a file on a computer. This is useful for creating a library of reusable configuration files on computers used for system installation.

Export

Choose a channel to save the PEQ setting, and select Export to file.

Import

Choose a channel to load the PEQ setting, and select Import from file.

When to Use the Channel and Automix Equalizers

Apply Automix EQ to make system-wide changes, such as a treble boost to improve speech clarity. Use Channel EQ to make adjustments to a specific channel. For example, to reduce unwanted noise picked up by only one channel.

Equalizer Applications

Conferencing room acoustics vary based on room size, shape, and construction materials. Use the guidelines in following table.

EQ Application Suggested Settings
Treble boost for improved speech intelligibility Add a high shelf filter to boost frequencies greater than 1 kHz by 3-6 dB
HVAC noise reduction Add a low cut filter to attenuate frequencies below 200 Hz
Reduce flutter echoes and sibilance Identify the specific frequency range that "excites" the room:
  1. Set a narrow Q value.
  2. Increase the gain to between +10 and +15 dB, and then experiment with frequencies between 1 kHz and 6 kHz to pinpoint the range of flutter echoes or sibilance.
  3. Reduce the gain at the identified frequency (start between -3 and -6 dB) to minimize the unwanted room sound.
Reduce hollow, resonant room sound Identify the specific frequency range that "excites" the room:
  1. Set a narrow Q value.
  2. Increase the gain to between +10 and +15 dB, and then experiment with frequencies between 300 Hz and 900 Hz to pinpoint the resonant frequency.
  3. Reduce the gain at the identified frequency (start between -3 and -6 dB) to minimize the unwanted room sound.

EQ Contours

Use the built-in equalizer contours to quickly apply EQ changes to all channels. EQ contours are separate from the per-channel EQ settings. Applying both EQ contours and per-channel EQ has a cumulative effect, meaning that the EQ changes stack on top of each other.

To enable a contour, open the web application and select a contour in the device options section.

Off: Turns off any active EQ contours

High Pass (default): 300 Hz low-cut filter

Low Shelf: 960 Hz, -10 dB low-shelf filter

Multi-Band: 200 Hz low-cut filter, parametric 450 Hz, -10 dB, 2.87 Q, ½ octave parametric, 900 Hz, -10 dB, 2.87 Q, ½ octave parametric

Click Bypass all EQ to quickly bypass any EQ contours or channel EQ settings.

Best Practices

  • Listen to and test your system as you make EQ changes, and make sure they work for your specific room.
  • When using with a P300 audio conferencing processor, turn off the microphone's channel EQ and EQ contours. Use the P300 to make EQ adjustments.

Custom Presets

Use presets to quickly save and recall settings. Up to 10 presets can be stored on each device to match various seating arrangements. A preset saves all device settings except for the Device Name, IP Settings, and Passwords. Importing and exporting presets into new installations saves time and improves workflow. When a preset is selected, the name displays above the preset menu. If changes are made, an asterisk appears next to the name.

Note: Use the default settings preset to revert to the factory configuration (excludes Device Name, IP Settings, and Passwords).

Open the presets menu to reveal preset options:

save as preset: Saves settings to the device
load preset: Opens a configuration from the device
import from file: Downloads a preset file from a computer onto the device. Files may be selected through the browser or dragged into the import window.
export to file: Saves a preset file from the device onto a computer

Mute and Fader Groups

Add channels to a Mute group or Fader group to link the corresponding controls together. For example, if channels 1, 2, and 3 are added to a Mute group, muting any of those individual channels will mute all of the grouped channels.

If you’re using Shure Designer software to configure your system, please check the Designer help section for more about this topic.

AES67

AES67 is a networked audio standard that enables communication between hardware components which use different IP audio technologies. This Shure device supports AES67 for increased compatibility within networked systems for live sound, integrated installations, and broadcast applications.

The following information is critical when transmitting or receiving AES67 signals:

  • Update Dante Controller software to the newest available version to ensure the AES67 configuration tab appears.
  • Before turning encryption on or off, you must disable AES67 in Dante Controller.
  • AES67 cannot operate when the transmit and receive devices both support Dante.
    Shure Device Supports: Device 2 Supports: AES67 Compatibility
    Dante and AES67 Dante and AES67 No. Must use Dante.
    Dante and AES67 AES67 without Dante. Any other audio networking protocol is acceptable. Yes

Separate Dante and AES67 flows can operate simultaneously. The total number of flows is determined by the maximum flow limit of the device.

Sending Audio from a Shure Device

All AES67 configuration is managed in Dante Controller software. For more information, refer to the Dante Controller user guide.

  1. Open the Shure transmitting device in Dante Controller.
  2. Enable AES67.
  3. Reboot the Shure device.
  4. Create AES67 flows according to the instructions in the Dante Controller user guide.

Receiving Audio from a Device Using a Different Audio Network Protocol

Third-party devices: When the hardware supports SAP, flows are identified in the routing software that the device uses. Otherwise, to receive an AES67 flow, the AES67 session ID and IP address are required.

Shure devices: The transmitting device must support SAP. In Dante Controller, a transmit device (appears as an IP address) can be routed like any other Dante device.

Encryption

Audio is encrypted with the Advanced Encryption Standard (AES-256), as specified by the US Government National Institute of Standards and Technology (NIST) publication FIPS-197. Shure devices that support encryption require a passphrase to make a connection. Encryption is not supported with third-party devices.

To activate encryption:

  1. Open the Settings menu and select the General tab.
  2. Select Enable Encryption.
  3. Enter a passphrase. All devices must use the same passphrase to establish an encrypted connection.

Important: For encryption to work:

  • All Shure devices on your network must use encryption.
  • Disable AES67 in Dante Controller. AES67 and AES-256 cannot be used at the same time.

If you’re using Shure Designer software to configure your system, please check the Designer help section for more about this topic.

Automix

Automix Channel

This channel automatically mixes the audio from all selected channels to deliver a convenient, single output. To adjust the automix channel settings, select the IntelliMix tab. All IntelliMix DSP blocks can be applied to the automix channel.

To use the automix channel, do the following:

  1. Send to Mix is automatically selected (blue) for all channels. To exclude channels from the automix channel and treat them as individual direct outputs, deselect Send to Mix (gray).
  2. Route the automix channel in Dante Controller to the desired output.

Automix Modes

Gating

Gating mode delivers fast-acting, seamless channel gating and consistent perceived ambient sound levels. Off-attenuation in this mode is fixed at -20 dB per channel, regardless of the number of open channels.

Gain Sharing

Gain sharing mode dynamically balances system gain between open and closed channels. The system gain remains consistent by distributing gain across channels to equal one open channel. The scaled gain structure helps to reduce noise when there is a high channel count. When fewer channels are used, the lower off-attenuation provides transparent gating.

Manual

Manual mode sums all active tracks and sends the summed signal over a single Dante output. This provides the option to route an individual signal for reinforcement or recording, without enabling automixing. The settings from the faders in the standard monitoring view apply to the summed output.

Automix Settings

Leave Last Mic On

Keeps the most recently used microphone channel active. The purpose of this feature is to keep natural room sound in the signal so that meeting participants on the far end know the audio signal has not been interrupted.

Gating Sensitivity

Changes the threshold of the level at which the gate is opened

Off Attenuation

Sets the level of signal reduction when a channel is not active

Hold Time

Sets the duration for which the channel remains open after the level drops below the gate threshold

Maximum Open Channels

Sets the maximum number of simultaneously active channels

Priority

When selected, this channel gate activates regardless of the number of maximum open channels.

Always On

When selected, this channel will always be active.

Send to Mix

When selected, sends the channel to the automix channel.

Solo

Mutes all of the other channels

Automix Gain Meter

When enabled, changes gain meters to display automix gating in real time. Channels that gate open will display more gain than channels that are closed (attenuated) in the mix.

Automix Modes (Firmware <4.x only)

Classic

Classic mode emulates the Shure SCM820 automixer (in its default settings). It is renowned for fast-acting, seamless channel gating and consistent perceived ambient sound levels. Off-attenuation in this mode is fixed at -20 dB per channel, regardless of the number of open channels.

Smooth

In Smooth mode, Off-attenuation settings for each channel are scaled, depending on the number of open channels. The scaled gain structure helps to reduce noise when there is a high channel count. When fewer channels are used, the lower off-attenuation provides transparent gating.

Number of channels enabled Off-attenuation (dB)
2 -5
3 -8
4 -10
5 -12
6 -13
7 -14
8 -15

Custom

Custom mode provides control over all automixing parameters. This mode is useful when adjustments must be made to one of the preset modes to fit a particular application. If parameters are changed in smooth or classic mode, custom mode automatically activates.

Manual

Manual mode sums all active tracks and sends the summed signal over a single Dante output. This provides the option to route the signal for reinforcement or recording, without enabling automixing. The settings from the faders in the standard monitoring view apply to the summed output.

IntelliMix DSP

This device contains IntelliMix digital signal processing blocks that can be applied to the automix channel output. The DSP blocks include:

  • Acoustic echo cancellation (AEC)
  • Automatic gain control (AGC)
  • Noise reduction
  • Compressor
  • Delay

To access the DSP blocks, select the IntelliMix tab. When enabled, each DSP block will be colored.

Selecting Bypass IntelliMix will bypass the following DSP blocks: AEC, AGC, noise reduction, compressor, and delay.

DSP Best Practices

  • Apply DSP blocks only as needed. Run a test of your system without DSP, and then add processing as needed to fix any issues that you hear in the audio signal.
  • Unless you encounter video that lags behind audio, set Delay to off.
  • DSP blocks do not affect whether the automixer gates a channel on or off.

Acoustic Echo Cancellation

In audio conferencing, a far-end talker may hear their voice echo as a result of a near-end microphone capturing audio from loudspeakers. Acoustic echo cancellation (AEC) is a DSP algorithm which identifies the far-end signal and stops it from being captured by the microphone to deliver clear, uninterrupted speech. During a conference call, the AEC works constantly to optimize processing as long as far-end audio is present.

When possible, optimize the acoustic environment using the following tips:

  • Reduce speaker volume
  • Position speakers farther from microphones
  • Avoid pointing speakers directly at microphone coverage areas

Selecting a Reference Signal for AEC

To apply AEC, provide a far end reference signal. For best results, use the signal that also feeds your local reinforcement system.

P300: Go to Schematic and click any AEC block. Choose the reference source, and the reference source changes for all AEC blocks.

MXA910: Route a far-end signal to the AEC Reference In channel.

AEC Settings

Reference Meter

Use the reference meter to visually verify the reference signal is present. The reference signal should not be clipping.

ERLE

Echo return loss enhancement (ERLE) displays the  dB level of signal reduction (the amount of echo being removed). If the reference source is connected properly, the ERLE meter activity generally corresponds to the reference meter.

Reference

Indicates which channel is serving as the far end reference signal.

Non-Linear Processing

The primary component of the acoustic echo canceller is an adaptive filter. Non-linear processing supplements the adaptive filter to remove any residual echo caused by acoustic irregularities or changes in the environment. Use the lowest possible setting that is effective in your room.

Low: Use in rooms with controlled acoustics and minimal echoes. This setting provides the most natural sound for full duplex.

Medium: Use in typical rooms as a starting point. If you hear echo artifacts, try using the high setting.

High: Use to provide the strongest echo reduction in rooms with bad acoustics, or in situations where the echo path frequently changes.

Noise Reduction

Noise reduction significantly reduces the amount of noise in the signal caused by projectors, HVAC systems, or other environmental noise. It is a dynamic processor, which calculates the noise floor in the room and removes noise throughout the entire spectrum with maximum transparency.

Settings

The noise reduction setting (low, medium, or high) represents the amount of reduction in  dB. Use the lowest possible setting that effectively lowers noise in the room.

Automatic Gain Control (AGC)

Automatic gain control automatically adjusts channel levels to ensure consistent volume for all talkers, in all scenarios. For quieter voices, it increases gain; for louder voices, it attenuates the signal.

Enable AGC on channels where the distance between the talker and the microphone may vary, or in rooms where many different people will use the conferencing system.

Automatic gain control happens post-gate (after the automixer), and will not affect when the automixer gates on or off.

Target Level (dBFS)

Use -37 dBFS as a starting point to ensure adequate headroom, and adjust if necessary. This represents the RMS (average) level, which is different from setting the input fader according to peak levels to avoid clipping.

Maximum Boost ( dB)

Sets the maximum amount of gain that can be applied

Maximum Cut ( dB)

Sets the maximum attenuation that can be applied

Tip: Use the boost/cut meter to monitor the amount of gain added or subtracted from the signal. If this meter is always reaching the maximum boost or cut level, consider adjusting the input fader so the signal is closer to the target level.

Delay

Use delay to synchronize audio and video. When a video system introduces latency (where you hear someone speak, and their mouth moves later), add delay to align audio and video.

Delay is measured in milliseconds. If there is a significant difference between audio and video, start by using larger intervals of delay time (500-1000 ms). When the audio and video are slightly out of sync, use smaller intervals to fine-tune.

Compressor

Use the compressor to control the dynamic range of the selected signal.

Threshold

When the audio signal exceeds the threshold value, the level is attenuated to prevent unwanted spikes in the output signal. The amount of attenuation is determined by the ratio value. Perform a soundcheck and set the threshold 3-6 dB above average talker levels, so the compressor only attenuates unexpected loud sounds.

Ratio

The ratio controls how much the signal is attenuated when it exceeds the threshold value. Higher ratios provide stronger attenuation. A lower ratio of 2:1 means that for every 2 dB the signal exceeds the threshold, the output signal will only exceed the threshold by 1 dB. A higher ratio of 10:1 means a loud sound that exceeds the threshold by 10 dB will only exceed the threshold by 1 dB, effectively reducing the signal by 9 dB.

Networking and Dante

Digital Audio Networking

Dantetm digital audio is carried over standard Ethernet and operates using standard Internet Protocols. Dante provides low latency, tight clock synchronization, and high Quality-of-Service (QoS) to provide reliable audio transport to a variety of Dante devices. Dante audio can coexist safely on the same network as IT and control data, or can be configured to use a dedicated network.

Switch Recommendations for Dante Networking

In addition to the basic networking requirements, Dante audio networks should use a Gigabit network switch or router with the following features:

  • Gigabit ports
  • Quality of Service (QoS) with 4 queues
  • Diffserv (DSCP) QoS, with strict priority
  • Recommended: A managed switch to provide detailed information about the operation of each network link (port speed, error counters, bandwidth used)

Cable Requirements

Always use Cat5E cable or higher.

QoS (Quality of Service) Settings

QoS settings assign priorities to specific data packets on the network, ensuring reliable audio delivery on larger networks with heavy traffic. This feature is available on most managed network switches. Although not required, assigning QoS settings is recommended.

Note: Coordinate changes with the network administrator to avoid disrupting service.

To assign QoS values, open the switch interface and use the following table to assign Dante-associated queue values.

  • Assign the highest possible value (shown as 4 in this example) for time-critical PTP events
  • Use descending priority values for each remaining packet.
Dante QoS Priority Values
Priority Usage DSCP Label Hex Decimal Binary
High (4) Time-critical PTP events CS7 0x38 56 111000
Medium (3) Audio, PTP EF 0x2E 46 101110
Low (2) (reserved) CS1 0x08 8 001000
None (1) Other traffic BestEffort 0x00 0 000000

Note: Switch management may vary by manufacturer and switch type. Consult the manufacturer's product guide for specific configuration details.

DSCP (Differentiated Services Code Point): Standardized identification method for data used in layer 3 QoS prioritization

Networking

Networking Best Practices

Use the following best practices when setting up a network to ensure reliable communication:

  • Always use a "star" network topology by connecting each component directly to the switch or router.
  • Connect all Shure networked devices to the same network and set to the same subnet. It is also required in order to open the web application for a device.
  • Devices on separate networks require an audio processor or conferencing software to carry audio between them. See the system planning and gear requirements section for network setup information and configuration examples.
  • Use only 1 DHCP server per network. Disable DHCP addressing on additional servers.
  • Power on the switch and DHCP server prior to MXA equipment.
  • To expand the network, use multiple Ethernet switches in a star topology.
  • All devices must be at the same firmware revision level.

Network Audio and Shure Control Data

MicroflexAdvance devices transport two types of data over the network: Shure Control and Network Audio.

Shure Control

The Shure Control carries data for the control software operation, firmware updates and 3rd party control systems (AMX, Crestron).

Network Audio

This network carries both the Dante digital audio and the control data for Dante Controller. The network audio requires a wired, gigabit Ethernet connection to operate.

Device IP Settings

Configure IP

Sets IP mode of the selected network interface:

  • Auto (DHCP): For automatic assignment of IP addresses.
  • Manual (Static): For Static IP addresses.

IP Settings

View and edit the IP Address, Subnet Mask, and Gateway for each network interface.

MAC Address

The network interface's unique identification.

Configuring IP Settings

IP configurations are managed in Shure Designer software. By default, they are set to Automatic (DHCP) mode. DHCP mode enables the devices to accept IP settings from a DHCP server, or automatically fall back to Link-Local settings when no DHCP is available. IP addresses may also be manually set.

To configure the IP properties, follow these steps:

  1. Open device's configuration window.
  2. Go to the Settings tab and select Network.
  3. Select Auto or Manual. If Auto is used, addresses will be automatically assigned. For Manual setup, follow the instructions on manual configuration.

Manually Assigning Static IP Address

To manually assign IP addresses, follow these steps:

  1. Open the device's configuration window in Designer.
  2. Go to the Settings tab and select Network.
  3. Select Manual as the Configure IP setting.
  4. Enter the IP settings.

Setting Latency

Latency is the amount of time for a signal to travel across the system to the outputs of a device. To account for variances in latency time between devices and channels, Dante has a predetermined selection of latency settings. When the same setting is selected, it ensures that all Dante devices on the network are in sync.

These latency values should be used as a starting point. To determine the exact latency to use for your setup, deploy the setup, send Dante audio between your devices, and measure the actual latency in your system using Audinate's Dante Controller software. Then round up to the nearest latency setting available, and use that one.

Use Audinate's Dante Controller software to change latency settings.

Latency Recommendations

Latency Setting Maximum Number of Switches
0.25 ms 3
0.5 ms (default) 5
1 ms 10
2 ms 10+

Operating the Control Software over Wi-Fi

When operating the web application over Wi-Fi, it’s important to set up the wireless router properly for best performance. The system employs several standard-based protocols that rely on multicast. Wi-Fi treats broadcast and multicast packets differently than general packets for backward compatibility reasons. In some cases, the Wi-Fi router will limit the multicast packet transmission rate to a value that is too slow for web application to properly operate.

Wi-Fi routers typically support 802.11b, 802.11a/g, and/or 802.11n standards. By default, many Wi-Fi routers are configured to allow older 802.11b devices to operate over the network. In this configuration, these routers will automatically limit the multicast data rates (or sometimes referred to as ‘basic rate’, or ‘management rate’) to 1-2Mbps.

Note: A Wi-Fi connection can only be used for the control software. Network audio cannot be transmitted over Wi-Fi.

Tip: For larger wireless microphone configurations, it’s recommended to increase the multicast transmission rate to provide adequate bandwidth.

Important: For best performance, use a Wi-Fi router that does not limit the multicast rate to 1-2 Mbps.

Shure recommends the following Wi-Fi router brands:

  • Cisco
  • Linksys
  • Apple

Packet Bridge

Packet bridge enables an external controller to obtain IP information from the control interface of a Shure device. To access the packet bridge, an external controller must send a query packet over unicast UDP* to port 2203 on the Dante interface of the Shure device.

  1. Send a UDP packet with a minimum 1-byte payload .

    Note: The maximum accepted payload 140 bytes. Any content is allowed.

  2. The Shure device will send a response packet over unicast UDP to the controller, using a destination UDP port identical to the source port of the query packet. The payload of the response packet follows this format:
    Bytes Content
    0-3 IP address, as 32-bit unsigned integer in network order
    4-7 Subnet mask, as 32-bit unsigned integer in network order
    8-13 MAC address, as array of 6 bytes

    Note: The Shure device should respond in less than one second on a typical network. If there is no response, try sending the query again after verifying the destination IP address and port number.

These protocols require multicast. Ensure multicast has been correctly configured for your network.

Echo Reduction (Firmware <4.x only)

In audio conferencing, a talker may hear their voice echo as a result of the microphone capturing far-end audio from loudspeakers.

The echo reduction feature prevents the far-end signal from activating the microphone. Ideal for installations in which per-channel DSP echo cancellation is not within a project budget, echo reduction is highly effective for connecting directly to a computer or video codec which hosts a single-channel echo canceller.

How It Works

An echo reference signal from the far end is routed through Dante Controller software to the microphone's processing algorithm. The processor uses this signal to prevent the microphone from gating on and capturing audio from the loudspeakers.

Enabling Echo Reduction

  1. Use Dante Controller software to route the incoming far end audio signal to the Echo Reduction Reference In channel on the MXA910.
  2. In the MXA910 web application, enter Configuration> AUTOMIX
  3. Enable echo reduction by selecting a strength setting in the pull-down menu. Soft, medium, and hard settings provide far-end attenuation and apply gain to the reference channel to ensure proper gating.Note: the off-attenuation setting changes to -56 dB, and the Leave last microphone on setting is set to OFF when echo reduction is enabled.

Using a Third-Party Control System

This device receives logic commands over the network. Many parameters controlled through Designer can be controlled using a third-party control system, using the appropriate command string.

Common applications:

  • Mute
  • LED color and behavior
  • Loading presets
  • Adjusting levels

Troubleshooting

Problem Solution
Software lags in Google Chrome browser Problem is browser-related. Turn off hardware acceleration option in Chrome.
Sound quality is muffled or hollow
  • Check that lobes have been aimed to the desired area.
  • Use equalizer to adjust frequency response on a single channel or on the automix channel. See the equalizer applications for the appropriate use.
Microphone does not show up in device discovery
  • Ensure the devices are powered
  • Ensure PC and equipment are on the same network and set to the same subnet
  • Turn off other network interfaces not used to connect to the device (including WiFi)
  • Check that DHCP server is functioning (if applicable)
  • Reset the device if necessary
Audio is not present or is quiet/distorted
  • Check cables
  • Verify that channels are not muted
  • Make sure channels are aimed in the right direction
  • Check that fader levels are not set too low
  • If using automixing, check the settings to ensure channels are gating on/off properly
No lights Check if brightness is disabled or if any Light Bar settings are turned off.
Auto-positioning identifies incorrect location If talker is in a corner or very close to a wall, acoustic reflections may interfere with localization accuracy. Try automatic positioning again, and if the issue persists, manual positioning may be necessary.
Microphone does not power on
  • The network switch must supply Power over Ethernet. Otherwise, a PoE injector must be used
  • Check network cables and connections

Lobe Sensitivity

The edge of the blue coverage area for each channel in the web application represents where the sensitivity reaches -6 dB. Understanding how lobe sensitivity is displayed helps to:

  • Provide complete coverage in a space, either by adding lobes or changing the lobe width. This ensures the sensitivity is within 6 dB in all areas. It is acceptable for lobes to slightly overlap.
  • Ensure that spacing and isolation are adequate to reduce noise and maximize automatic mixing performance.
