MXA902

Integrated Conferencing Ceiling Array

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 shure.com/designer)

Step 1: Install and Connect

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.

Connect the computer running Designer to the same network.

Open Designer. Check that you’re connected to the correct network in Settings.

Go to Online devices. To identify devices, click the product icon to flash the lights on a device. Find the MXA902 in the

list.

Check if there are firmware updates available for the MXA902 and install the latest. You can also use Shure Update

Utility (download at shure.com/suu).

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.

In Designer, create a new room. Drag and drop the MXA902 and the ANIUSB-MATRIX to add them to the room.

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.

Check the audio routes and settings to make sure they fit your needs.

Step 3: Listen and Adjust

Connect a computer with videoconferencing software (such as Zoom or Microsoft Teams) installed on it to the ANIUSB-

MATRIX's USB port.

Open the ANIUSBMATRIX's matrix mixer in Designer. Make sure that the box where the Dante input and the USB out

put intersect is checked (this sends the microphone signal to the computer).

Open the videoconferencing software on the computer connected to the ANIUSB-MATRIX. In the settings, choose the

ANIUSB-MATRIX as the speaker and microphone.

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.

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 com

pleting 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:

Cat5e (or better) Ethernet cable

Network switch that provides Power over Ethernet Plus (PoE+)

Shure Web Device Discovery and Dante Controller software

Step 1: Install and Connect

Install the microphone and connect it to a PoE+ port on the network switch using Ethernet cable.

Connect the computer running Shure Web Device Discovery and Dante Controller to the same network.

Open Shure Web Device Discovery. Find the MXA902 in the list of devices and doubleclick to open the web applica

tion.

Step 2: Route Audio

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

Open Dante Controller and find the MXA902 in the list of transmitters and receivers.

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.

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 loud

speaker (the loudspeaker signal is also set as the AEC reference).

In your videoconferencing software, make sure to select the correct microphone and loudspeaker sources.

Step 3: Listen and Adjust

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.

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 ad

justments.
