•
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 adequa
te 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.

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.
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.
•
Like all microphones, tonality changes as the distance from the source increases.
•
The pickup area of the microphone increases slightly as it is mounted higher.
