Getting Started

MXA902 Designer Setup

The MXA902 microphone and loudspeaker intelligently covers all talkers inside the 20 x 20-foot (6.1 x 6.1 m) coverage area. IntelliMix® DSP sends a clear signal for the far end, with AEC, noise reduction, and more on a single output. The loudspeaker provides high-quality speech reproduction for the entire 20 x 20-foot (6.1 x 6.1 m) coverage area.

After completing this basic setup process, you should be able to:

  • Discover the MXA902 in Designer
  • Adjust DSP settings, route audio, and change loudspeaker levels

You will need:

  • Cat5e or better Ethernet cable (shielded cable recommended)
  • Network switch that provides Power over Ethernet Plus (PoE+)
  • Shure Designer software (download at

Step 1: Install and Connect

A Shure MXA902 connected to a PoE+ port on a switch. A computer running Shure Designer software is connected to the same network.

  1. Install the MXA902 and connect it to a PoE+ port on the network switch using Ethernet cable. If your switch doesn't supply PoE+, the loudspeaker does not play sound and the error LED flashes.
  2. Connect the computer running Designer to the same network.
  3. Open Designer. Check that you’re connected to the correct network in Settings.
  4. Go to Online devices. To identify devices, click the product icon to flash the lights on a device. Find the MXA902 in the list.
  5. Check if there are firmware updates available for the MXA902 and install the latest. You can also use Shure Update Utility (download at

Step 2: Route Audio and Apply DSP

The easiest way to route audio and apply DSP is with Designer's optimize workflow. Optimize routes audio signals, applies DSP settings, turns on mute synchronization, and enables LED control for connected devices.

For this example, we'll connect an MXA902 and an ANIUSB-MATRIX.

  1. In Designer, create a new room. Drag and drop the MXA902 and the ANIUSB-MATRIX to add them to the room.
  2. Select Optimize. Designer sends the microphone signal to the ANIUSB-MATRIX, sets the MXA902's loudspeaker as the AEC reference, and makes other DSP changes. You can also route audio manually in Designer or Dante Controller.
  3. Check the audio routes and settings to make sure they fit your needs.

    Screenshot showing the Shure MXA902's output routed to an ANIUSB-MATRIX. The ANIUSB sends a far-end signal to the MXA902's input.

Step 3: Listen and Adjust

  1. Connect a computer with videoconferencing software (such as Zoom or Microsoft Teams) installed on it to the ANIUSB-MATRIX's USB port.
  2. Open the ANIUSB-MATRIX's matrix mixer in Designer. Make sure that the box where the Dante input and the USB output intersect is checked (this sends the microphone signal to the computer).

    Checkbox showing a connection between the ANIUSB-MATRIX's Dante input and USB output.

  3. Open the videoconferencing software on the computer connected to the ANIUSB-MATRIX. In the settings, choose the ANIUSB-MATRIX as the speaker and microphone.
  4. Place a test call with the whole system. Have the far-end caller tell you how the microphone signal sounds and make adjustments as needed:
    • Microphone: [Your room] > MXA902 > IntelliMix
    • Loudspeaker: [Your room] > MXA902 > Loudspeaker > Speaker output.
  5. If needed, move the microphone's coverage area up to 4 feet (1.2 m) in any direction: [Your room] > Coverage map. You can also listen to the microphone signal directly using a Dante headphone amp to help make adjustments.

Important: Use Designer 4.7.25 or newer to discover the MXA902. Refer to MXA902 Limitations for details about using the MXA902 with Designer 4.7.25 and certain Shure device firmware.

MXA902 Web Application Setup

Out of the box, the MXA902 has a 20 x 20-foot (6.1 x 6.1 m) coverage area for microphone pickup and speech reproduction. You can shift the microphone coverage up to 4 feet (1.2 m) in any direction using Designer or the web application. After completing this basic setup process, you should be able to:

  • Access the MXA902's web application
  • Adjust DSP settings, route audio, and change loudspeaker levels

You will need:

Step 1: Install and Connect

  1. Install the microphone and connect it to a PoE+ port on the network switch using Ethernet cable.
  2. Connect the computer running Shure Web Device Discovery and Dante Controller to the same network.
  3. Open Shure Web Device Discovery. Find the MXA902 in the list of devices and double-click to open the web application.

Step 2: Route Audio

To route audio to and from other Dante devices, use Dante Controller.

  1. Open Dante Controller and find the MXA902 in the list of transmitters and receivers.
  2. Find the Dante device you're sending the MXA902's microphone signal to in the list of receivers. To make an audio route, check the box where the MXA902's automix output intersects with the receiver device's input channel.
  3. To route far-end audio to the MXA902's loudspeaker, check the box where the transmitter device's channel intersects with one of the MXA902's 2 Dante input channels in the receiver list. The 2 inputs are summed and sent to the loudspeaker (the loudspeaker signal is also set as the AEC reference).
  4. In your videoconferencing software, make sure to select the correct microphone and loudspeaker sources.

Step 3: Listen and Adjust

  1. Place a test call with the whole system. Have the far-end caller tell you how the microphone signal sounds and make adjustments in the web application as needed:
    • Microphone: MXA902 web application > IntelliMix
    • Loudspeaker: MXA902 web application > Loudspeaker > Speaker output.
  2. If needed, move the microphone's coverage area up to 4 feet (1.2 m) in any direction: MXA902 web application > Coverage map. You can also listen to the microphone signal directly using a Dante headphone amp to help make adjustments.

How to Update Firmware Using Designer

Applies to Designer 4.2 and newer.

Before setting up devices, check for firmware updates using Designer to take advantage of new features and improvements. You can also install firmware using Shure Update Utility for most products.

To update:

  1. Open Designer. If there's new firmware that you haven't downloaded yet, Designer shows a banner with the number of updates available. Click to download firmware.
  2. Go to Online devices and find your devices.
  3. Choose a firmware version for each device from the Available firmware column. Make sure that no one is editing device settings during an update.
  4. Select the checkbox next to each device you plan to update and click Update firmware. Devices may disappear from Online devices during an update. Don't close Designer while updating firmware.

MXA902 Coverage

The MXA902 uses Single-Zone Automatic Coverage technology. There is one 20 x 20-foot (6.1 x 6.1 m) coverage area that captures every talker in it with minimal configuration. The MXA902's integrated loudspeaker provides natural-sounding speech reproduction for the entire coverage area.

To access microphone coverage settings:

  • Designer: Add the microphone to a room and go to Coverage map.
  • Web application: Go to Coverage.

Any talker in the blue coverage area has microphone coverage. Click and drag to move the coverage area up to 4 feet (1.2 m) in any direction.

Screenshot of the Shure MXA902's square blue coverage map, which is set at 20 by 20 feet (6.1 x 6.1 m).

The MXA902 provides 1 automixed output with IntelliMix DSP for the far end. For most rooms, all you need to do is install the microphone above the coverage area and route the audio signal using Shure Designer software or Dante Controller.

How Much Space Does the MXA902 Cover?

The MXA902's microphone coverage area is set at 20 x 20 feet (6.1 x 6.1 m). For most rooms, Shure recommends:

  • Maximum distance from talker to microphone: 16 feet (4.9 m)
  • Maximum mounting height: 10 feet (3 m)

The maximum distance from talker to microphone and maximum mounting height also depend on your room's acoustics, construction, and materials. Acoustically treated rooms that are less reverberant generally sound better and help improve your microphone signal.

The MXA902's loudspeaker delivers high-quality speech reproduction for the entire 20 x 20-foot (6.1 x 6.1 m) coverage area.

Adjust Microphone and Loudspeaker Levels

To adjust levels, open the MXA902 in Designer or the device web application.

Microphone Levels

To adjust, go to IntelliMix.

  1. Make a test call with your videoconferencing software.
  2. Talk in all parts of the coverage area at a normal speech volume and have someone on the far end listen to your signal. Adjust levels as needed. The coverage area gain fader is post-gate.
  3. Adjust EQ settings as needed. You can use EQ to improve speech intelligibility and control problematic frequencies in a room (such as a low-frequency rumble caused by HVAC systems). You can also make changes to IntelliMix DSP blocks here.
  4. If needed, listen to the microphone signal directly using a Dante headphone amp or with Dante Virtual Soundcard.

Loudspeaker Levels

To adjust, go to Loudspeaker and use the Speaker output fader.

Make a test call with your videoconferencing software and adjust the loudspeaker level as needed. If you set a higher loudspeaker level, you may need to use a higher NLP setting on the AEC block to remove echo.

If needed, use the signal generator to help with EQ adjustments. The signal generator is pre-EQ.

Mute the MXA902

The MXA902 has multiple mute points for controlling the microphone, the loudspeaker, or both:

Screenshot of the Shure MXA902's software showing the IntelliMix output mute, device mute buttons, Dante input mutes, and the speaker output mute.

  1. IntelliMix output mute: Mutes the microphone's Dante output channel
  2. Dante input mute: Mutes the selected Dante input channel
  3. Speaker output mute: Mutes the loudspeaker output
  4. Device mute: Mutes everything (microphone and loudspeaker). This mute button also changes the mute status LED.

Use Designer's Optimize Workflow

Designer's optimize workflow speeds up the process of connecting systems with at least 1 microphone and 1 audio processor. Optimize also creates mute control routes in rooms with MXA network mute buttons. When you select Optimize in a room, Designer does the following:

  • Creates audio routes and mute control routes
  • Adjusts audio settings
  • Turns on mute synchronization
  • Enables LED logic control for applicable devices

The settings are optimized for your particular combination of devices. You can customize settings further, but the optimize workflow gives you a good starting point. Optimize works with any device in Designer.

To use the optimize workflow:

  1. Place all relevant devices in a room.
  2. Select Optimize. Designer optimizes microphone and DSP settings for your equipment combination.

    If you remove or add devices, select Optimize again.

After optimizing a room, check and adjust settings to fit your needs. You may need to:

  • Delete unnecessary routes.
  • Check levels and adjust gain.
  • Check that AEC reference signals are correctly routed.
  • Fine-tune DSP blocks as needed.

Note: In the Routing view, a dotted line indicates a broken route that will not pass audio.

Broken Routes

Possible reasons:

  • Devices controlled by Dante Domain Manager (DDM). Resolve the issues in DDM.
  • Devices controlled by Dante device lock. Resolve the issues with Dante device lock.
  • Devices have mismatched encryption settings. Resolve the issues with encryption settings.
  • Devices have mismatched passphrases. Resolve the passphrase issue.
  • Devices located on different subnets. Resolve the issue by manually routing devices.

Hovering over devices provides additional information about the issue.

Important: Use Designer 4.7.25 or newer to discover the MXA902. Refer to MXA902 Limitations for details about using the MXA902 with Designer 4.7.25 and certain Shure device firmware.

How to Install the MXA902

There are many ways to install the MXA902 to get great coverage in small- to medium-sized meeting rooms.

Installation Best Practices

  • Don't place the microphone behind obstructions.
  • Coverage depends on your room's acoustics, construction, and materials. Take these into consideration when planning.
  • For most rooms, Shure recommends 10 feet (3 m) as the maximum mounting height.

Mounting options:

Install in a Ceiling Grid

Before you begin:

  • Remove the plastic cover from the grille.
  • Remove the cardboard piece between the loudspeaker and the back panel.
  • If using, install the rubber pads on the corners of the microphone to prevent scratches.

    Illustration showing how to install the rubber pads on Shure ceiling array microphones to prevent scratching.

  • Verify that your ceiling grid size matches your model variation.
  • If using the A910-JB junction box, install it before ceiling installation.

IMPORTANT: Do not install the 60 cm model in a 2-foot (609.6 mm) ceiling grid.

  1. Make space in the ceiling grid for the array microphone to be installed.
  2. Route the Ethernet cable above the ceiling grid and through the opening in the ceiling.
  3. Plug the Ethernet cable into the microphone.
  4. Attach the safety tether between the building structure and one of the tie-off points on the back of the microphone using braided metal cable or other high-strength wire (not included). This safety measure prevents the microphone from falling in an emergency situation. Make sure there is no tension on the safety tether. Follow any local regulations.
  5. Install the microphone in the ceiling grid.

5 steps showing how to install Shure's square ceiling array microphones in tile ceiling grids.

The MXA902-S-60CM is not designed or intended to be installed within a 24” ceiling grid, which is the standard grid size 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.

Installing the Junction Box Accessory

The A910-JB junction box mounts on square ceiling array microphones to connect conduit. There are 3 knockouts on the junction box for attaching conduit. See local regulations to determine if the junction box is necessary.

Note: Install the junction box on the microphone before installing the microphone in the ceiling.

3 arrows pointing to the different knockouts available on the Shure ceiling array junction box.

To install:

  1. Remove the knockout you plan to use on the junction box.
  2. Remove the 4 screws from the microphone as shown.

  • Screw specification: M4 thread (hole depth = 9.15 mm)
  • Hole spacing: 100 mm square

The VESA mounting holes are compatible with these Shure accessories:

Suspending from the Ceiling

Illustration showing how to use the 4 mounting eyelet screws to suspend square Shure ceiling arrays from a ceiling.

Suspend the microphone using your own equipment, or with Shure's A900-GM kit (includes mounting cables and hooks).

To mount using your own equipment, you will need:

  • Braided metal cable or high-strength wire
  • Hardware to attach cable to ceiling
  1. Attach the mounting cables to the 12 mm diameter eyelet screws on the microphone.
  2. Attach the cables to the ceiling using appropriate hardware.

Install on a Ceiling with the A900-CM

Attach array microphones to the ceiling with the A900-CM mounting kit.

Refer to the A900-CM user guide to learn how to install on other ceiling materials.

Dante Channels

The MXA902 has:

  • 2 input channels
  • 1 automix output with IntelliMix DSP

The 2 input channels are summed and sent to the loudspeaker's output. These input channels are useful if you need to send a far-end signal and program audio to the loudspeaker.

The MXA902's AEC reference is the same signal sent to the integrated loudspeaker and can't be changed.

IntelliMix DSP

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

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

To access, go to the IntelliMix tab.

DSP Best Practices

  • Apply DSP blocks 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.

Acoustic Echo Cancellation

In AV conferencing, a person may hear their voice echo. This happens when a near-end microphone picks up audio from the room's loudspeakers and sends it back to the far end as echo.

Acoustic echo cancellation (AEC) is a DSP algorithm that gets rid of distracting echo in your microphone signal. AEC identifies the far-end signal and stops it from being captured by the near-end microphone. During a call, AEC works constantly to optimize processing as long as far-end audio is present. AEC is necessary for clear, uninterrupted calls.

The MXA902 uses the built-in loudspeaker as the AEC reference signal.

Note: If the loudspeaker is off and you still want to use AEC, route the far-end signal you want to cancel to one of the Dante inputs.

AEC Settings

Reference Meter

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


Echo return loss enhancement (ERLE) displays the dB level of signal reduction (the amount of echo being removed). The ERLE meter generally corresponds to the reference meter.


The MXA902's reference signal is set to the built-in loudspeaker, which is the sum of the 2 Dante inputs. When the loudspeaker is on, the reference signal is post-DSP.

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.

Choose the Right NLP Setting

If far-end callers hear echo, test different NLP settings to find one that works. In general, it's best to use the lowest NLP setting that removes echo from your mic signal.

The level of the MXA902's loudspeaker can also affect how well the AEC removes the reference signal from the mic's signal. Experiment with using a higher NLP setting when the loudspeaker level is higher.

Noise Reduction

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


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 does 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 (not available on all microphones) to monitor the amount of gain added or subtracted from the signal. If the meter is always reaching the maximum boost or cut level, adjust the input fader so the signal is closer to the target level.


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.


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


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.


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.

Parametric Equalizer

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

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

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

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 Contour

Use the EQ contour to quickly apply a high-pass filter at 150 Hz to the microphone's signal.

Select EQ contour to turn it on or off.


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.

In Designer, you can only enable encryption for all devices in a room in live mode: [Your room] > Settings > Audio encryption.

To activate encryption in the web application:

  1. Go to Settings > Audio encryption > Enable encryption.
  2. 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.

Important: Use Designer 4.7.25 or newer to discover the MXA902. Refer to MXA902 Limitations for details about using the MXA902 with Designer 4.7.25 and certain Shure device firmware.

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.

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

For more information, see our FAQ about switches to avoid.

Device IP Configuration

This Shure device uses 2 IP addresses: one for Shure control, and one for Dante audio and control.

  • Shure control
    • Carries data for Shure control software, firmware updates, and third-party control systems (such as AMX or Crestron)
  • Dante audio and control
    • Carries Dante digital audio and control data for Dante Controller
    • Requires a wired, gigabit Ethernet connection to operate

To access these settings in Designer, go to [Your device] > Settings > IP configuration.

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+

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.

Digital Audio Networking

Dante® 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.

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 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.

Refer to Dante Domain Manager's documentation for more information.

Dante Flows for Shure Devices

Dante flows get created any time you route audio from one Dante device to another. One Dante flow can contain up to 4 audio channels. For example: sending all 5 available channels from an MXA310 to another device uses 2 Dante flows, because 1 flow can contain up to 4 channels.

Every Dante device has a specific number of transmit flows and receive flows. The number of flows is determined by Dante platform capabilities.

Unicast and multicast transmission settings also affect the number of Dante flows a device can send or receive. Using multicast transmission can help overcome unicast flow limitations.

Shure devices use different Dante platforms:

Dante Platform Shure Devices Using Platform Unicast Transmit Flow Limit Unicast Receive Flow Limit
Brooklyn II ULX-D, SCM820, MXWAPT, MXWANI, P300, MXCWAPT 32 32
Brooklyn II (without SRAM) MXA920, MXA910, MXA902, MXA710, AD4 16 16
Ultimo/UltimoX MXA310, ANI4IN, ANI4OUT, ANIUSB-MATRIX, ANI22, MXN5-C 2 2
DAL IntelliMix Room 16 16

Learn more about Dante flows in our FAQs or from Audinate.


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.
