System Overview

① Dante audio, power, and control

A single network cable delivers 4 discrete audio channels from each microphone onto the Dante network, where they can be routed to any Dante-compatible devices.

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

A computer running Dante Controller and the Shure browser-based interface provides control over the following:

Control:

A computer connected to the network controls the microphone through a web-based control application . Coverage, muting, LED behavior, gain, and network settings are controlled remotely.

Audio:

Dante™ audio is routed through Dante™ controller software. Dante™ Virtual Soundcard enables audio monitoring and recording directly on the computer.

System Planning and Gear Requirements

Setting up the Audio Network

Shure networked conferencing systems are comprised of Microflex Advance microphones and network interfaces, which operate entirely on a Dante network. Additional hardware, including network switches, computers, loudspeakers, and audio processors are described in the hardware component index.

Shure components shown in this diagram:

Microflex Advance Microphones

The MXA910 and MXA310 are equipped with Dante outputs, and connect directly to a network switch.

Audio Network Interfaces

The interfaces are used to connect analog devices such as loudspeakers and analog microphones to the network.

ANI4IN: Converts 4 analog signals (separate XLR and block connector models available) into Dante digital audio signals.

ANI4OUT: Converts 4 channels of Dante audio from the network into analog signals.

This diagram shows the entire signal path through a networked conference system. Signals from the near end and far end are exchanged through an audio processor connected to a phone system, or through a computer connected to the internet. Analog microphones connect to the network through the Shure ANI4IN, while loudspeakers connect through the Shure ANI4OUT.

This diagram shows Microflex Advance components in context, with two rooms communicating through video codecs.

Controlling Hardware and Audio Over the Network

Audio and hardware settings are managed through a computer connected to the same network.

Shure Hardware and Audio

Each Microflex Advance component has a web application which provides mixing and configuration tools to optimize sound quality.

Expanded Control for Analog Devices

Analog devices that are connected to the network through a Shure network interface (ANI4IN/ANI4OUT) benefit from additional remote control: Volume levels, equalization, and signal routing are managed through the web application. For example, adjusting loudspeaker volume or muting a wired microphone, which would normally be done from the hardware, can now be controlled remotely over the network.

Dante Signal Routing

Signal routing between devices is managed through Dante Controller software, provided by Audinate™.

Hardware Component Index

Network Switch

The network switch provides central connectivity for all networked components. Audio from any networked Shure microphones that are connected to the switch can be routed to any Dante-enabled device. The switch sends and receives audio and control data, while simultaneously powering the microphones and audio network interfaces through PoE (Power over Ethernet). See the network switch requirements for additional details.

Power over Ethernet (PoE) Requirements:

All Shure components included in these scenarios require Power over Ethernet (class 0). If not provided through the network switch, a PoE injector is required to power the devices.

Shure Microflex Wireless Audio Network Interface (MXWANI)

The Microflex Wireless Audio Network Interface (MXWANI) is a digital-to-analog breakout box with a built-in gigabit network switch. It converts digital audio from the network into analog signals for signal processing or amplification, and provides PoE over one network port to power a device. For details, refer to the Microflex Wireless user guide, available at http://www.shure.com.

Audio Processor

The audio processor sends and receives audio through a VOIP server or a standard phone line. They also provide digital signal processing, such as acoustic echo cancellation.

Dante-enabled

Processors that support Dante connect directly to the network switch to receive audio from Microflex Advance microphones.

Analog

When using an analog processor, a converter (such as the Shure ANI4OUT or MXWANI) is required to deliver the analog audio from Microflex Advance microphones to the processor.
Video Codec

Like the audio processor, the codec sends and receives audio signals alongside video signals between the near end and the far end. Audio from the near end must connect to the audio input on the video codec, which is typically a stereo analog connection. The Shure ANI4OUT Audio Network Interface converts the audio to an analog signal for connecting to a codec.

Shure ANI4IN Audio Network Interface (Analog-to-Dante Converter)

The Shure ANI4IN Audio Network Interface converts 4 channels of analog audio into independent digital audio channels on a Dante network. Adjustable gain and +48V phantom power deliver the flexibility to support line, auxiliary, and microphone-level devices. For networked conferencing systems, the Audio Network Interface provides a simple way to connect previously installed analog equipment onto the audio network, such as wireless microphones for presenters. The web application gives technicians and administrators control over channel levels and settings from any computer connected to the same network.

Shure ANI4OUT Audio Network Interface (Dante-to-Analog Converter)

The Shure ANI4OUT Audio Network Interface converts 4 channels of Dante digital audio into discrete analog signals. Available in both XLR and block connector versions, each box uses a single network cable to receive audio and power using Power over Ethernet (PoE). The web application gives technicians and administrators control over channel levels and settings from any computer connected to the same network.

Amplifiers and Loudspeakers

Audio from the far end is routed to local loudspeakers. Dante-enabled speakers or amplifiers connect directly to the network switch, while analog systems require an audio network interface to receive networked audio.

Computers and Control Systems

Browser-Based Web Application

A computer connected to the network provides control of Shure networked components through the web application for each device.

Dante Software

A computer running Dante Virtual Soundcard, Dante Controller, and web conferencing software is used to send and receive audio between the near end and far end.

Control Systems (AMX, Crestron, etc.)

If using a third-party control system, Microflex Advance microphones send and receive commands over Ethernet. If an analog logic signal must be sent over the network, the Shure ANI4IN Audio Network Interface receives analog logic signals and converts them into Ethernet control strings.

System Scenarios

The following diagrams show a selection of common conferencing room systems. Use them as a reference when planning hardware and cable requirements for an installation. Each diagram includes:

  • Signal flow and connections

  7. Attach the remaining rubber washer and wing nut from underneath the table. Then, tighten the wing nut to secure the microphone on the table.

    Optional: use the hole in the wing nut to insert a cable tie for cable management.

Power Over Ethernet (PoE)

This device requires PoE to operate. It is compatible with both Class 0 and Class 2 PoE sources.

Power over Ethernet is delivered in one of the following ways:

  • A network switch that provides PoE
  • A PoE injector device

Microphone Placement

Microphone Placement

Each microphone has 4 channels that can be aimed independently, based on the seating arrangement. Each channel features independent polar patterns and additional channel settings, accessible through the web application.

The web application provides increased positioning flexibility over traditional conferencing microphones:

  • Configurable pickup areas can be rotated and modified for the number of talkers.
  • Network connectivity, device identification, and presets allow moving, adding and removing microphones with ease.
  • Independent channels and automixing make Dante signal routing simple and flexible.
  • Customized presets can be saved to immediately recall different room configurations.

Seating Scenarios

Each channel can capture one or several talkers. In rooms with flexible furniture arrangements, microphones can be moved to cover various seating arrangements as long as they are plugged into the same network.

Note: Settings are saved on each microphone, and are retained when plugged into a different network port. Presets can be recalled and deployed through the web application, or through an external control system.

Single-Microphone Applications (Multiple Channels)

With four independent channels and polar patterns, coverage can be customized to match the table shape, size, and seating arrangement. The automatic mixing feature helps reduce extraneous noise (such as typing or paper shuffling) from interfering with speech intelligibility on the far end.

Toroid Pattern Applications

The toroid pattern rejects sound from directly above the microphone to reduce noise from video projectors or other sources of unwanted sound. It is the simplest way to ensure equal coverage among all talkers, while retaining the benefits of the rejection provided by a directional polar pattern. When this pattern is used, the audio is sent over a single channel. Therefore, when automatic mixing is desired, configure the microphone to use multiple directional patterns instead of the toroid pattern.

Noise from a ceiling-mounted projector is rejected, while all talkers are covered.

For a table with a single microphone and more than 4 talkers, the toroid pattern to ensures that all voices are heard equally.

Coverage With Multiple Microphones

For large tables, a series of microphones captures all talkers. Place the microphones in the center of the table for balanced pickup and accurate aiming. For the best audio quality and clarity, use enough microphones so that each talker has their own channel.

A table with 10 people is covered by 4 microphones, with an independent channel for each person.

For a large table with 2 microphones, place the microphones to cover equally sized areas. Use the Toroid or Omnidirectional setting to cover the entire table.

Software Installation, Management, and Security

Accessing the Web Application

The Shure Web Server Discovery application finds all Shure devices on the network that feature a web-based GUI. Follow these steps to install the software and access the web application:

① Install the Shure Discovery application

Download and install the Shure Discovery application from www.shure.com. This automatically installs the required Bonjour device discovery tool on the computer.

② Connect the network

Ensure the computer and the hardware are on the same network.

③ Launch the Discovery application

The app displays all Shure devices that feature a GUI.

④ Identify the hardware

Double-click on a device to open its GUI in a web browser.

⑤ Bookmark the device's web application (recommended)

Bookmark the device's DNS name to access the GUI without the Shure Discovery app.

Web Application Browser Compatibility

The web application is compatible with all HTML5-supported browsers. To ensure the best performance, disabling hardware acceleration and unused plug-ins is recommended.

Accessing the Web Application without the Discovery App

If the Discovery application is not installed, the web application can be accessed by typing the DNS name into an internet browser. The DNS name is derived from model of the unit, in combination with the last three bytes (six digits) of the MAC address, and ending in .local.

Format Example: If the MAC address of a unit is 00:0E:DD:AA:BB:CC, then the link is written as follows:

MXA310: http://MXA310-aabbcc.local

Using A Password

All settings are configurable by default. To protect settings with a password, open the Settings menu and select the General tab. In this screen, passwords can be created or changed.

Once a password has been set, a Read-Only option appears on the log-in screen. In Read-Only mode, device parameters can be viewed, but not edited. Device identification remains active.

Firmware Updates

Firmware is embedded software in each component that controls functionality. Periodically, new versions of firmware are developed to incorporate additional features and enhancements. To take advantage of design improvements, new versions of the firmware can be uploaded and installed using the Shure Update Utility. Software is available for download from http://www.shure.com.

Important: When components are connected through the Shure MXW Audio Network Interface, their firmware must be updated on one device at a time prior to updating the MXW Audio Network Interface firmware. Attempting to update all devices at once will cause the interface to reboot after its firmware is updated, and the connection to other networked components will be lost.

Perform the following steps to update the firmware:

CAUTION! Ensure the device has a stable network connection during the update. Do not turn off the device until the update is complete.

  1. Connect the device and computer to the same network (set to the same subnet).
  2. Download Shure Update Utility app and install it.
  3. Open the application.
  4. Click Check For Updates... button to view new firmware versions available for download.
  5. Select the desired firmware and press Downloadto download it to the Firmware Library.
  6. From the Update Devices tab, select the new firmware and press Send Updates... to begin the firmware update, which overwrites the existing firmware on the device.

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

Control Software Overview

The boundary microphone user interface provides flexible, in-depth control of the microphone to deliver exceptional results for nearly any room. The following control options are quickly accessible through a web browser on a desktop or mobile device:

  • Channel levels, monitoring, and mute status
  • Polar pattern selection
  • Pickup area aiming
  • Security and network settings
  • Automix settings
  • Light settings
  • External control switch configuration

Microphone Configuration

The microphone features multiple configurations to adapt to any meeting space, based on these variables:

  • Table size and shape
  • Number of meeting participants
  • Participant seating arrangement

Selecting Pickup Patterns

  1. Select Configuration > Coverage
  2. Select a channel to reveal the Channel Properties
  3. Use the Polar Pattern pull-down menu to make a selection
Pickup Pattern Directional Characteristic Use When

Omnidirectional

Picks up sound with equal sensitivity from all directions Participants are likely to move around, or when additional sound sources are located away from the microphone. The omnidirectional pattern performs best in a quiet, controlled environment. Note: Omnidirectional channels are not sent to the automix channel.

Toroid

Picks up sound from the edges of the microphone, while rejecting sounds from directly above it. Rooms have a higher level of ambient noise, or when noise from above is a concern (a video projector, for example).

Bi-directional

Captures sound on two opposite sides of the microphone in a figure-8 pattern Two talkers are facing each other, sitting on opposite sides of a table. The bi-directional pattern provides better off-axis rejection than the two talkers setting, but does not allow independent gain adjustment for each talker.

One, Two, Three, or Four Talkers

Each pickup area features independent polar pattern control. Select each polar pattern setting based on the number of talkers in each pickup area and the table size or shape. Available patterns include:
  • Cardioid
  • Supercardioid
  • Toroid
  • Omnidirectional
  • Bi-directional
  • Hypercardioid
Maximum noise rejection and channel separation are desired, and when the seating configuration is unlikely to change. This configuration is optimal for use with automixing.

Aiming Pickup Areas

All pickup patterns (except omnidirectional and toroid) can be aimed directly at individual talkers to provide the clearest possible signal with minimal room ambience. In the Configuration menu, aim the pickup lobes by selecting and dragging the channel. The angle can also be adjusted in 15° increments from the channel properties menu on the right side of the workspace.

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

Templates

Use a template as a starting point when configuring coverage. Templates only adjust coverage, and do not affect gain levels or other settings.

  1. Select the template that is the closest match to the seating scenario
  2. Select OK
  3. If channels must be added, select the template with the desired channel count. This is the only way to add channels to a configuration.

Adjusting Channel Levels

Each of the 4 microphone channels feature independent gain control. This feature is useful when meeting participants are seated at unequal distances from the microphone.

To adjust the level, move the fader up or down or manually enter a gain setting.

When the microphone is centered on a rectangular table, use the channel gain to balance the levels and compensate for the unequal distances.

Adjusting Levels

Gain levels on Microflex ®Advance microphones must be set for each saved coverage preset to ensure 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.

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.

Identifying Channels

Identify a channel on the microphone by flashing the corresponding LED. This quickly verifies that level or equalizer adjustments are being made to the intended channel.

  1. Select Configuration > Coverage
  2. Select a channel
  3. Use the Identify Channel button to flash the LEDs on the microphone

Note: The equalizer can only be assigned to a single channel on the MXA310.

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

Automix Channel

This channel automatically mixes the audio from all channels to deliver a convenient, single output. The automix channel must be routed in Dante Controller to the desired output.

  1. Select Channels
  2. In the AUTOMIX channel, select the AUTOMIX button

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.

Automix Modes

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 -12 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 -3.0
3 -4.8
4 -6

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.

Reset

The reset button is located inside a small hole in the lower half of the microphone. Use a paperclip or other small tool to press the button.

There are two reset functions:

Network reset (press button for 4-8 seconds)

Resets all Shure control and audio network IP settings to factory defaults

Full factory reset (press button for longer than 8 seconds)

Restores all network and web application settings to the factory defaults.

Software Reset Options

To simply revert settings without a complete hardware reset, use one of the following options:

Reboot Device:In the web application (settings > factory reset), there is a Reboot Device button, which simply power-cycles the device as if it were unplugged from the network. All settings are retained when the device is rebooted.

Default Settings: To revert audio settings back to the factory configuration (excluding Device Name, IP Settings, and Passwords), select Load Preset and choose the default settings preset.

Low-cut Filter

The low-cut filter rolls off low frequencies to reduce unwanted noise from sources such as table vibrations, HVAC systems, and other environmental noise.

To enable, open the web application and select the low-cut filter button in the device options section.

Mute Buttons

Four touch-sensitive mute buttons are indicated by the mute icons around the edge of the microphone. Pressing any of these buttons mutes the entire device. In the web application, channels can be muted individually. If the Light Ring is set to display Segments, the individual channel mutes are visible on the device. If it is set to Ring, the Light Ring only displays the device mute status.

To configure button properties through the web application, go to mic configuration>Button Control>Button Properties.

Mute Control Function

  • Local: mutes/unmutes audio from the microphone
  • Logic out: sends a command string to a control system to mute the audio farther down the signal path
  • Disabled: button is inactive

Mute Control Mode

  • Toggle on/off: Press the button to switch between mute and active states
  • Push to talk: Hold the button to activate the microphone when speaking
  • Push to mute: Hold the button to mute the microphone

Default Toggle State

Determines whether the microphone is muted or active when powered on

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 the Enable Encryption checkbox.
  3. Enter a passphrase. All devices must use the same passphrase to establish an encrypted connection.

Important: For encryption to work:

  • Encryption must be universally enabled or disabled on all connected Shure devices
  • AES67 must be disabled in Dante Controller to turn encryption on or off. AES67 encryption is currently not supported.

Using a Third-Party Control System

The microphone can send an external logic control signal to any networked devices that receive logic signals through an Ethernet connection. This allows the microphone mute switch to mute a DSP audio signal, instead of (or in addition to) muting the microphone at the source. The microphone also receives logic commands over the network. Many parameters controlled through the web application can be controlled through a third party control system, using the appropriate command string.

Common applications:

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

A complete list of command strings is available in the device help or from www.shure.com.

To send a logic signal out when the mute button is pressed:

  1. In the web application, select Configuration > Button Control.
  2. Under the Button Properties menu, change the Mute Control Function setting to Logic out.

MXA310 MicroflexAdvance Command Strings

The device is connected via Ethernet to a control system, such as AMX, Crestron or Extron.

Connection: Ethernet (TCP/IP; select “Client” in the AMX/Crestron program)

Port: 2202

Conventions

The device has 4 types of strings:

GET

Finds the status of a parameter. After the AMX/Crestron sends a GET command, the MXA310 responds with a REPORT string

SET

Changes the status of a parameter. After the AMX/Crestron sends a SET command, the MXA310 will respond with a REPORT string to indicate the new value of the parameter.

REP

When the MXA310 receives a GET or SET command, it will reply with a REPORT command to indicate the status of the parameter. REPORT is also sent by the MXA310 when a parameter is changed on the MXA310 or through the GUI.

SAMPLE

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)

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.

Networking Terminology

PTP (Precision Time Protocol): Used to synchronize clocks on the network

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

Dante Transmit Flows

For each device, there is a limit of 2 transmit flows and 2 receive flows. A single flow consists or either a single unicast or multicast transmission, and supports up to 4 audio channels.

  • A unicast flow is a point-to-point connection between 2 devices, supporting up to 4 channels per flow. To send 8 channels of audio between two devices, 2 unicast flows are required.
  • A multicast flow is a one-to-many transmission, which supports sending up to 4 channels to multiple receiving devices across the network. To send 8 channels from one device to all others on the network, 2 multicast flows are required.

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. This applies to all devices that audio signals must be routed between (managed through Dante Controller). 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 through the web application. 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 the web application.
  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 web application.
  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.

The latency setting for Dante devices should be set according to the number of switches in the network.

Use Audinate's Dante Controller software to change the latency setting.

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.
