MXA920

Ceiling Array Microphone

Getting Started

Designer Setup

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

Discover the MXA920 in Designer

Add coverage areas

Adjust DSP settings and route audio

You will need:

Cat5e (or better) Ethernet cable

Network switch that provides Power over Ethernet (PoE)

Shure Designer software installed on a computer. Download at shure.com/designer.

Step 1: Install and Connect

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

Connect your 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 MXA920 in the

list.

Step 2: Route Audio

The easiest way to route audio and apply DSP is with Designer's Optimize workflow. Optimize automatically routes audio sig

nals, applies DSP settings, turns on mute synchronization, and enables LED control for connected devices.

For this example, we'll connect an MXA920 and a P300.

Go to My projects > New project to make a new project.

Select New > Room (live). Any online devices appear in the list. Drag and drop the MXA920, P300, and any other de

vices to add them to your room.

Select Optimize. You can also route audio manually in Designer outside of the Optimize workflow, or use Dante Con

troller.

◦

Check the audio routes and settings to make sure they fit your needs. You might need to:

Delete unnecessary routes.

Verify that AEC reference signals are correctly routed.

Fine-tune DSP blocks as needed.

Send audio from the P300 to other sources using the matrix mixer. A common destination is a computer connected by

USB with conferencing software.

Step 3: Add Coverage

The default setting is a 30 by 30 foot (9 by 9 meter) dynamic coverage area. Any talker inside has coverage, and anything out

side that area won't be picked up.

To add more coverage areas:

Go to [Your room] > Coverage map and select the MXA920.

Select Add coverage and choose a dynamic or a dedicated coverage area. You can add any combination of up to 8

coverage areas per microphone. Move and resize as needed.

Set up a way to listen to the microphone directly (with a Dante headphone amp, for example). Place a test call with the

whole conferencing system. Adjust gain and DSP as needed to get a good room sound.

You can also turn off automatic coverage in Settings to manually position up to 8 lobes.

Web Application Setup

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

Access the MXA920's web application

Add coverage areas

Route audio to other Dante devices using Dante Controller

You will need:

Cat5e (or better) Ethernet cable

Network switch that provides Power over Ethernet (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 MXA920 in the list of devices, and doubleclick to open the web applica

tion.

Step 2: Add Coverage

The default setting is a 30 by 30 foot (9 by 9 meter) dynamic coverage area. Any talker inside has coverage, and anything out

side that area won't be picked up.

To add more coverage areas:

Go to Coverage > Add coverage.

Choose a dynamic or a dedicated coverage area. You can add any combination of up to 8 coverage areas per micro

phone. Move and resize as needed.

Set up a way to listen to the microphone directly (with a Dante headphone amp, for example). Adjust the gain and DSP

as needed to get a good room sound. There are gain faders for each coverage area and for the automix output.

You can also turn off automatic coverage in Settings to manually position up to 8 lobes.

Step 3: Route Audio

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

Open Dante Controller and find the MXA920 in the list of transmitters. With automatic coverage on, the MXA920 only

sends audio from the automix output. Transmit channels 1-8 only work when automatic coverage is off.

Find the Dante device you're sending audio to in the list of receivers. To make an audio route, check the box where the

MXA920's automix output intersects with the receiver device's input channel.

Place a test call with the whole conferencing system. Adjust coverage, gain, and DSP as needed.
