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 Shure Designer provides control over the following:

Control:

A computer connected to the network controls the microphone with Shure Designer software. You can remotely control coverage, muting, LED behavior, 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.

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

You can manage signal routing with Dante Controller or Shure Designer software.

System Use Cases

These use cases will help you understand how Shure devices fit in conference rooms, huddle rooms, and multipurpose spaces.

Each diagram includes:

  • Signal flow and connections
  • Required devices

Power Over Ethernet and Hardware Requirements

All Shure devices included in these use cases require Power over Ethernet (PoE, class 0). Refer to the Dante and Networking section for additional information on cable and network switch requirements.

Telephone Conference with Shure MXW Audio Network Interface

① Array microphone to Shure MXWANI

Connect the microphone output to port 1 on the MXWANI with a network cable. Port 1 provides the necessary Power over Ethernet (PoE).

  1. Remove the screw that holds in the cable-retaining tab closest to the cable exit
  2. Remove the cable-retaining tab
  3. Insert the plug
  4. Replace the screw to secure the plug

Permanent Table Installation

  1. Remove the 3 screws located in the center on the bottom of the microphone

  2. Plug a network cable into the microphone and guide it through the center exit path. When the cable is secured, guide it through the tube.

    Note: If necessary, remove the retaining tabs to install thicker cable. Replace them after the cable is installed.

  3. Align the tube into the recessed area in the center of the microphone. Install the 3 screws (removed in step 1) to secure the tube.

  4. Slide one of the rubber washers to the base of the tube.

  5. Drill a 1-inch (2.5 cm) hole through the table.

  6. Guide the cable through the hole in the table. Then, place the tube through the hole in the table and gently press the microphone down.

  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

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. You can control these settings in Shure Designer software or in the device's web application.

Designer software 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 using Designer software, the web application, or 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.

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.

Adding or Removing a Channel

To add or remove a channel, go to Configuration.

  • Select Add Channel to add another channel.
  • Select Remove Channel or press the Delete key on your keyboard to remove a channel.

Removing a channel also deletes any EQ or gain settings applied to that channel.

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. Select Add Channel or Remove Channel to adjust coverage.

Adjusting Levels

Input 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.

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.

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

  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 Automix 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.

Automix Gain (Post-Gate)

To adjust, go to Configuration > Automix. 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.

Note: The level meters in Configuration > Automix only display pre-gate channel gain, but the faders will adjust post-gate channel gain.

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.

Identifying Channels

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.

  • 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.

Mute Synchronization

Mute synchronization ensures that all connected devices in a conferencing system mute or unmute at the same time and at the correct point in the signal path. Mute status is synchronized in the devices using logic signals or USB connections.

To use mute synchronization, enable logic on connected devices using the web application or Shure Designer software. Many Shure devices have logic enabled automatically.

If you use Designer's Optimize workflow, Designer configures all of the necessary mute synchronization settings for you.

Shure logic devices:

  • P300 (Also mutes supported soft codecs connected by USB)
  • ANIUSB-MATRIX (Also mutes supported soft codecs connected by USB)
  • MXA910
  • MXA710
  • MXA310
  • Network Mute Button
  • ANI22-BLOCK
  • ANI4IN-BLOCK
  • Logic-enabled MX microphones connected to ANI22-BLOCK or ANI4IN-BLOCK
    • MX392
    • MX395-LED
    • MX396
    • MX405/410/415

Setting Up Mute Sync on the MXA310 and P300

Use this setup to mute the P300 by pressing the mute button on the MXA310. In the P300’s signal chain, muting happens after the DSP so that the AEC stays converged.

  1. Open the P300 in Designer and go to Inputs.
  2. On any channel strip, select Logic enable. This enables logic on all channels.
  3. Open the MXA310 in Designer and go to Settings > Logic control.
  4. Set the Mute control function to Logic out.
  5. Go to Lights. Set the style to Ring.

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.

Note: Automix is disabled when using the toroid polar pattern. Inversely, the toroid pattern cannot be selected when automix is enabled.

To enable automixing and modify settings:

  1. Select Configuration
  2. Open the AUTOMIX tab
  3. Check the Enable box

To modify settings from the channels screen:

  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 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

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.

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

A complete list of command strings is available at:

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 and Cable Recommendations for Dante Networking

Switches and cables determine how well your audio network performs. Use high-quality switches and cables to make your audio network more reliable.

Network switches should have:

  • Gigabit ports. 10/100 switches may work on small networks, but gigabit switches perform better.
  • Power over Ethernet (PoE) or PoE+ ports for any devices that require power
  • Management features to provide information about port speed, error counters, and bandwidth used
  • Ability to switch off Energy Efficient Ethernet (EEE). EEE (also known as "Green Ethernet") may cause audio dropouts and problems with clock synchronization.
  • Diffserv (DSCP) Quality of Service (QoS) with strict priority and 4 queues

Ethernet cables should be:

  • Cat5e or better
  • Shielded

Compatibility with Dante Domain Manager

This device is compatible with Dante Domain Manager software (DDM). DDM is network management software with user authentication, role-based security, and auditing features for Dante networks and Dante-enabled products.

Considerations for Shure devices controlled by DDM:

  • When you add Shure devices to a Dante domain, set the local controller access to Read Write. Otherwise, you won't be able to access to Dante settings, perform a factory reset, or update device firmware.
  • If the device and DDM can't communicate over the network for any reason, you won't be able to control Dante settings, perform a factory reset, or update device firmware. When the connection is reestablished, the device follows the policy set for it in the Dante domain.
  • If Dante device lock is on, DDM is offline, or the configuration of the device is set to Prevent, some device settings are disabled. These include: Dante encryption, MXW association, AD4 Dante browse and Dante cue, and SCM820 linking.

See Dante Domain Manager's documentation for more information.

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 Best Practices

When connecting Shure devices to a network, use the following best practices:

  • Always use a "star" network topology by connecting each device directly to the switch or router.
  • Connect all Shure networked devices to the same network and set to the same subnet.
  • Allow all Shure software through the firewall on your computer.
  • Use only 1 DHCP server per network. Disable DHCP addressing on additional servers.
  • Power on the switch and DHCP server before powering on the Shure devices.
  • To expand the network, use multiple 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.
