How To Install The Mxa920 - Shure MXA920 Manual

Automatic Coverage On
1. Talk in each coverage area at a normal speech volume. You can adjust:
◦ Coverage area gain (post-gate): From the room's Coverage view, open the MXA920 properties panel on the right
side. Select the coverage area to see post-gate gain and mute controls.
◦ IntelliMix gain (post-gate): Go to the IntelliMix tab to adjust the automix output level and control DSP settings.
2. Adjust EQ settings as needed. You can use EQ to improve speech intelligibility and control problematic frequencies in a
room (such as a low­frequency rumble caused by HVAC systems). If your EQ changes cause a large increase or de­
crease in the level, adjust the levels as in step 1.
Automatic Coverage Off
In this mode, there are 2 sets of gain faders:
• Channel gain (pre-gate): To adjust, open the MXA920 controls in Designer and go to Channels. These faders affect a
channel's gain before it reaches the automixer and therefore affect the automixer's gating decision. Boosting the gain here
will make the lobe more sensitive to sound sources and more likely to gate on. Lowering gain here makes the lobe less
sensitive and less likely to gate on. If you're only using direct outputs for each channel without the automixer, you only
need to use these faders.
• IntelliMix gain (post-gate): To adjust, open the MXA920 controls in Designer and go to IntelliMix. Alternatively, select a
lobe in Coverage to see post­gate gain and mute controls in the properties panel. These faders adjust a channel's gain af­
ter the lobe has gated on. Adjusting the gain here will not affect the automixer's gating decision. Only use these faders to
adjust the gain of a talker after you are satisfied with the automixer's gating behavior.

How to Install the MXA920

There are many ways to install MXA920 microphones. See below for details about the mounting and accessory options for
square and round array microphones.
Microphone Placement Best Practices
Room Variables
Decide where to install the microphone by looking at the room's seating arrangements and infrastructure. Follow these guide­
lines for best results:
• Don't install the microphone behind obstructions.
• Install the microphone at least 4 feet (1.2 m) from noise sources. These include: air vents, projectors, or loudspeakers that
have high dB levels.
◦ Loudspeakers tend to have higher dB levels when installed above 10 feet (3 m).
• In rooms where talkers turn to face a screen, install the microphone toward the screen so talkers naturally talk toward the
microphone.
• In rooms with flexible seating arrangements or multiple microphones, use Designer to ensure that the coverage is ade­
quate for all seating scenarios.
◦ If installing multiple microphones, set up coverage areas so they don't overlap.
• Install acoustic treatment to improve speech intelligibility in rooms that are too reverberant.
• If you're planning to use
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.
X/Y/Z coordinates for camera tracking, install the MXA920 so that it's level and not angled.
