For most rooms, Shure recommends:
These numbers also depend on your room's acoustics, construction, and materials. With automatic coverage on, the default coverage area is a 30 by 30 foot (9 by 9 meter) dynamic coverage area.
When you use automatic coverage, the microphone captures talkers you want to hear and avoids areas you tell it to avoid. You can add a mix of up to 8 dynamic and dedicated coverage areas per microphone.
If you turn off automatic coverage, you can manually steer up to 8 lobes.
With automatic coverage on or off, the MXA920 uses Shure's Autofocus™ technology to fine-tune coverage in real time as talkers shift positions or stand. Autofocus is always active, and you don't need to adjust anything for it to work.Automatic coverage = On
When you open Coverage, there's a 30 by 30 foot (9 by 9 meter) dynamic coverage area ready to use. Any talker inside has coverage, even if they stand up or walk around.
Select Add coverage to add more coverage areas. You can use up to 8 coverage areas per microphone, and you can mix both types as needed. Drag and drop to move coverage areas.
Dynamic coverage areas have flexible coverage, which means that the microphone intelligently adapts to cover all talkers in the coverage area. Change the size to fit your space, and any talker within the boundaries of the coverage area will have microphone coverage (even as they move).
Dedicated coverage areas have microphone coverage at all times. They have a set size of 6 by 6 feet (1.8 by 1.8 meters) and work best for talkers that are in one position most of the time, like at a podium or a whiteboard.
As you set up coverage, you may want to block unwanted sounds from your microphone signal (such as doorways or HVAC equipment). There are 2 ways to block unwanted sounds in part of a room:
| Muted Coverage | No Coverage | |
|---|---|---|
| How does it sound? | Great rejection for unwanted sounds | Good rejection for unwanted sounds |
| Can unwanted sound get picked up? | No. Sounds inside muted coverage areas won’t be picked up by active coverage areas. | Possibly. Sounds outside coverage areas can be picked up at low levels by active coverage areas. |
| Does it use coverage areas? | Yes | No |
To use the muted coverage method:
To use the no coverage method:
Automatic coverage = Off
To use steerable lobes, turn off automatic coverage in . You can manually position up to 8 microphone lobes. This mode is best for when you need direct outputs, like for a multi-zone voice lift system.
The microphone doesn't use coverage areas when automatic coverage is off.
Before adjusting levels:
In this mode, there are 2 sets of gain faders:
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:
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.
After optimizing a room, you should check and adjust settings to fit your needs. These steps may include:
Compatible devices:
To use the Optimize workflow:
If you remove or add devices, select Optimize again.
Mute sync 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 sync, make sure logic is enabled on all devices.
Designer's Optimize workflow configures all necessary mute sync settings for you.
Compatible Shure logic devices:
To use mute sync, route the microphone’s signal to a processor that has logic turned on (P300, ANIUSB-MATRIX, or IntelliMix Room software). Microphones always have logic turned on.
For help with specific mute sync implementations, see our FAQs.
There are many ways to install MXA920 microphones. See below for details about the mounting and accessory options for square and round array microphones.
Square mounting options:
Round mounting options:
Before you begin:
IMPORTANT: Do not install the 60 cm model in a 2 foot (609.6 mm) ceiling grid.
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.
To install:
The rear plate has 4 threaded holes for attaching the microphone to a VESA mounting device. The mounting holes follow the VESA MIS-D standard:
The VESA mounting holes work with Shure's A900-PM and A900-PM-3/8IN accessories to mount the microphone on a pole.
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:
You can mount square ceiling array microphones in hard ceilings without a tile grid using the A910-HCM accessory.

The automatic coverage setting changes the number of Dante outputs on the MXA920.
Note: When automatic coverage is on, Dante Controller shows 8 transmit channels and the automix output. The automix output is the only channel that sends audio with automatic coverage on.
This device contains IntelliMix digital signal processing blocks that can be applied to the microphone's output. The DSP blocks include:
To access, go to the IntelliMix tab.
In audio conferencing, a far-end talker may hear their voice echo as a result of a near-end microphone capturing audio from loudspeakers. Acoustic echo cancellation (AEC) is a DSP algorithm which identifies the far-end signal and stops it from being captured by the microphone to deliver clear, uninterrupted speech. During a conference call, the AEC works constantly to optimize processing as long as far-end audio is present.
When possible, optimize the acoustic environment using the following tips:
To apply AEC, provide a far end reference signal. For best results, use the signal that also feeds your local reinforcement system.
P300: Go to Schematic and click any AEC block. Choose the reference source, and the reference source changes for all AEC blocks.
MXA910, MXA920, MXA710: Route a far-end signal to the AEC Reference In channel.
IntelliMix Room: Go to Schematic and click an AEC block. Choose the reference source. Each block can use a different reference source, so set the reference for each AEC block.
Designer's Optimize workflow automatically routes an AEC reference source, but it's a good idea to check that Designer chooses the reference source you want to use.
Reference Meter
Use the reference meter to visually verify the reference signal is present. The reference signal should not be clipping.
ERLE
Echo return loss enhancement (ERLE) displays the dB level of signal reduction (the amount of echo being removed). If the reference source is connected properly, the ERLE meter activity generally corresponds to the reference meter.
Reference
Indicates which channel is serving as the far end reference signal.
Non-Linear Processing
The primary component of the acoustic echo canceller is an adaptive filter. Non-linear processing supplements the adaptive filter to remove any residual echo caused by acoustic irregularities or changes in the environment. Use the lowest possible setting that is effective in your room.
Low: Use in rooms with controlled acoustics and minimal echoes. This setting provides the most natural sound for full duplex.
Medium: Use in typical rooms as a starting point. If you hear echo artifacts, try using the high setting.
High: Use to provide the strongest echo reduction in rooms with bad acoustics, or in situations where the echo path frequently changes.
Noise reduction 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 automatically adjusts channel levels to ensure consistent volume for all talkers, in all scenarios. For quieter voices, it increases gain; for louder voices, it attenuates the signal.
Enable AGC on channels where the distance between the talker and the microphone may vary, or in rooms where many different people will use the conferencing system.
Automatic gain control happens post-gate (after the automixer), and will not affect when the automixer gates on or off.
Target Level (dBFS)
Use -37 dBFS as a starting point to ensure adequate headroom, and adjust if necessary. This represents the RMS (average) level, which is different from setting the input fader according to peak levels to avoid clipping.
Maximum Boost ( dB)
Sets the maximum amount of gain that can be applied
Maximum Cut ( dB)
Sets the maximum attenuation that can be applied
Tip: Use the boost/cut meter to monitor the amount of gain added or subtracted from the signal. If this meter is always reaching the maximum boost or cut level, consider adjusting the input fader so the signal is closer to the target level.
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.
Threshold
When the audio signal exceeds the threshold value, the level is attenuated to prevent unwanted spikes in the output signal. The amount of attenuation is determined by the ratio value. Perform a soundcheck and set the threshold 3-6 dB above average talker levels, so the compressor only attenuates unexpected loud sounds.
Ratio
The ratio controls how much the signal is attenuated when it exceeds the threshold value. Higher ratios provide stronger attenuation. A lower ratio of 2:1 means that for every 2 dB the signal exceeds the threshold, the output signal will only exceed the threshold by 1 dB. A higher ratio of 10:1 means a loud sound that exceeds the threshold by 10 dB will only exceed the threshold by 1 dB, effectively reducing the signal by 9 dB.
Maximize audio quality by adjusting the frequency response with the parametric equalizer.
Common equalizer applications:
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. |
These features make it simple to use effective equalizer settings from a previous installation, or simply accelerate configuration time.
Use to quickly apply the same PEQ setting across multiple channels.
Use to save and load PEQ settings from a file on a computer. This is useful for creating a library of reusable configuration files on computers used for system installation.
| Export | Choose a channel to save the PEQ setting, and select Export to file. |
| Import | Choose a channel to load the PEQ setting, and select Import from file. |
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:
|
| Reduce hollow, resonant room sound | Identify the specific frequency range that "excites" the room:
|
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: .

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

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.
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:
See Dante Domain Manager's documentation for more information.
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, MXA710, AD4 | 16 | 16 |
| Ultimo/UltimoX | MXA310, ANI4IN, ANI4OUT, ANIUSB-MATRIX, ANI22, MXN5-C | 2 | 2 |
| DAL | IntelliMix Room | 16 | 16 |
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:
| 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.
All AES67 configuration is managed in Dante Controller software. For more information, refer to the Dante Controller user guide.
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.
