Getting Started Designer Setup Example This example uses Designer 6.0 to connect an MXA920 and a P300. The process is similar when using other combinations of devices in Designer, so use these steps as a starting point. After completing this basic setup process, you should be able to: •... - Page 5 MXA920 output to P300 input ◦ P300 output to MXA920 AEC reference input You can also route audio manually in Designer or use Dante Controller. Check the audio routes, matrix mixer routes, and other settings to make sure they fit your needs. You might need to: ◦...

Page 6: Web Application Setup Example
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 doubleclick to open the web applica tion. - Page 7 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. Route a far-end reference signal to the MXA920's AEC reference input. The AEC reference is usually the same one that feeds the room's loudspeakers.

Page 13: Mxa920 Coverage
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. In rooms with well-controlled acoustics, you can mount the MXA920 higher than 12 feet and achieve great results. Refer to Mi... - Page 14 Shure Incorporated To add coverage areas: • Designer: In the coverage view, select the MXA920, then Properties > Coverage > Add coverage • Web application: Select Add coverage 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.
- Page 15 Shure Incorporated Dynamic Coverage Areas Dynamic coverage areas have flexible coverage. 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).

MXA920 so that it’s level and not angled. Mounting Height For most rooms, Shure recommends a mounting height of up to 12 feet (3.7 meters). In rooms with controlled acoustics, you can install the MXA920 higher than 12 feet and get great results. -
Page 18: Installing In A Ceiling Grid
Shure Incorporated Consider the following when choosing a mounting height: • The pickup pattern of the ceiling array is narrower than a shotgun microphone, so it can be placed farther from sound sources. There is no specific barrier at which the audio degrades or gates off. - Page 19 Shure Incorporated Installing the Junction Box Accessory The A910JB junction box mounts on square ceiling array microphones to connect conduit. There are 3 knockouts on the junc tion box for attaching conduit. See local regulations to determine if the junction box is necessary.
- Page 20 Shure Incorporated To install: Remove the knockout you plan to use on the junction box. Remove the 4 screws from the microphone as shown. Align the junction box with the screw holes. If possible, plug the network cable into the microphone before securing the junction box.

Page 29: Automix Modes
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 password to make a connection. Encryption is not supported with third-party devices. -
Page 30: Set Up The 802.1X Protocol For A Device
Select Shure devices support the IEEE 802.1X port access protocol for network authentication. Important: To use the 802.1X security protocol with Shure devices, set the network switch to multiple host authentication. You must also make accommodations to allow the audio NIC to connect to the network. The audio NIC doesn't support the 802.1X protocol. -
Page 31: Troubleshooting 802.1X Setup Issues
Always use a "star" network topology by connecting each device directly to the switch or router. • Connect all Shure networked devices to the same network and set to the same subnet. • Allow all Shure software through the firewall on your computer. -
