Ceiling Array Microphone

NOTICE

Due to a preliminary finding by a federal court in the United States, Shure is authorized to ship the MXA910-60CM. This model

is fully certified and lawful to use anywhere in the world but is not lawful to be used in the United States in a drop ceiling mount

ing configuration such as shown below. It is also unlawful to use adapters in an attempt to fit this smaller version to a ceiling

grid within the United States such that it mounts substantially as shown below.

Furthermore, the MXA91060CM is not designed or intended to be installed within a 24” ceiling grid, which is the standard size

grid in North America. Mounting in such a grid in the aboveshown configuration is unsafe and may cause damage to the prod

uct and/or injury to those below. The MXA910-60CM is safe and lawful for use in other mounting configurations, such as with

hard ceilings, or suspended from a VESA pole or suspension wiring, anywhere in the world.

A new version of the MXA910 for 24” ceiling grid installations in the United States is now available for preorder, with delivery

expected in December 2019. The MXA910W-A provides a quick, simple solution for installation in 24x24 inch ceiling grids in

the U.S. and includes the same technology and performance as all prior versions. For more information or to place a pre-order

for this new variant, visit www.shure.com/mxa910.

System Overview

①Dante audio, power, and control

Each array microphone connects to the network over a single network cable, which carries Dante audio, Power over Ether

net (PoE), and control information to adjust coverage, audio levels, and processing.

②Analog 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.

③Far-end audio (network to loudspeakers)

Danteenabled loudspeakers and amplifiers connect directly to a network switch. Analog loudspeakers and amplifiers con

nect through a Shure Network Interface (model ANI4OUT), which converts Dante audio channels into analog signals, deliv

ered through 4 discrete XLR or block connector outputs.

④Device control and Dante audio

Control: A computer connected to the network controls the microphone with Shure Designer software. You can remotely

adjust coverage, muting, LED behavior, lobe settings, gain, and network settings.

and recording directly on the computer.

Differences Between 3.x and 4.x Firmware

When you update an MXA910 from 3.x to 4.x firmware, you'll be able to use IntelliMix DSP features optimized for MXA.

Here's what changes with 4.x firmware:

IntelliMix DSP Added

You can now use AGC, AEC, noise reduction, compressor, and delay.

These DSP features don’t affect individual channel outputs—they only apply to the Automix Out channel

If you’re currently using the Automix Out channel on a 3.x device and you update it to 4.x, the following settings will be ap

plied automatically:

AGC: enabled

AEC: enabled

Noise reduction: enabled

Compressor: disabled

Delay: disabled

New Automixer Added

The 4.x automixer has different mix modes than the 3.x automixer.

Here's how mix mode settings will change:

3.x Automixer Setting New 4.x Automixer Setting

Classic Gating

Smooth Gain Sharing

Manual Manual

Custom Gating

New Autofocus Feature Added for All Lobes

Patent-pending Autofocus technology continually fine-tunes the position of each lobe in real time.

Lobes move automatically for consistent sound when participants lean back in their chairs or stand up.

Echo Reduction Removed

The microphone now has AEC, so there's no need for echo reduction.

The Echo Reduction Reference In channel's name in Dante Controller is now the "AEC Reference In" channel. Any exist

ing Dante route to that channel will persist.

Other Changes

Template 1's lobe positions have changed.

If you're using Template 1 with the default lobe positions, updating to 4.x will change your lobe positions.

After updating, all custom lobe positions and Dante routes will stay the same.

Getting Started

To control the MXA910, use Shure Designer software to adjust microphone coverage, apply DSP, and route audio between

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

Access and control the MXA910 in Designer

Apply DSP to the microphone's signal

Route audio from the microphone to other devices

Before you get started, you'll need:

Cat5e (or better) Ethernet cable

Network switch that provides Power over Ethernet (PoE)

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

Note: If Designer isn’t available, you can use a web application to control the MXA910 and Dante Controller to route audio. Download the Shure Web

Device Discovery application to access your device’s web application.

Step 1: Connect to a Network

Connect the microphone to a PoE port on the network switch using Cat5e (or better) cable.

Connect your computer running Designer to the network switch.

Step 2: Discover the MXA910 in Designer

Open Designer, and check that you’re connected to the correct network in Settings.

Click Online devices. A list of online devices appears.

To identify devices, click the product icon to flash the lights on a device. Select the MXA910 in the list and click Config

ure to open the device's configuration window.

Step 4: Apply DSP

With firmware 4.x and higher, the MXA910 includes IntelliMix DSP that can be applied to the automix channel output.

AEC, noise reduction, and automatic gain control (AGC) are on by default.

To use AEC, route a far-end reference signal to the microphone's AEC Reference In channel.

Use Designer to route a reference signal coming from a Shure device, like the ANIUSB-MATRIX or P300.

Use Dante Controller to route a reference signal from other third-party Dante devices.

Select IntelliMix, and click AEC.

Verify that the far-end signal is present on the reference meter. If it doesn't show up, check the routing.

To apply any other DSP blocks or edit settings, click the block icon.
