Ceiling Array Microphone
Overview
General Description
The Microflex Advance Ceiling Array is a premium networked array microphone for AV conferencing environments, including
boardrooms, huddle rooms, and multi-purpose spaces. The ceiling array uses Shure's Steerable Coverage with Autofocus
technology: 8 highly directional pickup lobes capture participant audio from overhead, continually fine-tuning the position of
each lobe in real time as participants lean back in their chairs or stand up .
The microphone also includes the IntelliMix DSP suite, which includes AEC, noise reduction, automatic mixing, and more.
Control the microphone with Shure Designer software, or a browserbased web application. The microphone integrates seam
lessly with Dante digital networked audio, AES67, and third-party preset controllers, including Crestron and AMX, to deliver a
high-quality AV conferencing experience that appeals equally to integrators, consultants, and meeting participants.

Network Connectivity
Discrete audio channels for each lobe and an automix channel are delivered over a single network cable
Dante digital audio coexists safely on the same network as IT and control data, or can be configured to use a dedicated
network
Control strings available for third-party preset controllers including Crestron and AMX
Professional Design
Sleek industrial design blends with contemporary board rooms and meeting spaces
Versatile mounting options for ceilings, pole mounts, suspension cables, and more
Available in white, black, and aluminum finishes (detachable grille can be custom painted)
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.

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.
Audio: Route audio with Dante Controller or Shure Designer software. Dante Virtual Soundcard enables audio monitoring
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 3: Adjust Microphone Coverage
To design microphone coverage, you'll need to create a Project and a Location. You can learn more about both in Designer’s
Help section.
From My projects, select New to create a new project.
Click New to add a location to your project. Once you enter a name, a new window for the location opens.
Click Live mode. Any online devices appear in the list.
In Designer, you can also design systems with virtual devices and send settings to real devices. Learn more in
Designer’s Help section.
Drag and drop the MXA910 to add it to your location.
Select Coverage map to adjust the microphone's coverage.
Use Auto position to let the software position each channel for you.
Click and drag to adjust each channel's position. Learn more in the Configuring Microphone Coverage section.

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.
