Installation
Microphone Placement
Room Variables
Optimal microphone placement is determined by the seating arrangements and infrastructure. Follow these guide
lines for the best possible results:
• In rooms with flexible furniture arrangements or multiple array microphones, use the microphone configuration
tool in the web application or Shure Designer software to ensure that the coverage is adequate for all seating
scenarios.
• The lobes should be pointed towards the front of each talker. Carefully consider placement in rooms where talk
ers may face a screen during a video conference.
• Avoid installing the microphone directly next to unwanted sound sources, such as air vents or noisy video pro
jectors.
• Consider installing acoustic treatment to improve speech intelligibility in rooms that are too reverberant.
Mounting Height
The maximum mounting height that can be set is 30 feet (9.14 meters). In a typical acoustic environment , the mi
crophone maintains an "A" rating based on the STIPA (Speech Transmission Index for Public Address systems)
international standard at distances up to 16 feet between the microphone and talker. In better acoustic environ
ments, the STIPA "A" rating may extend beyond 16 feet.
Consider the following when determining a mounting height:
• The pickup pattern of the ceiling array is narrower than a shotgun microphone, and therefore it can be placed
farther from the source than any other microphone. While the web application shows an ideal coverage zone for
each channel, keep in mind that there is no specific barrier at which the audio degrades or gates off. Lobe sen
sitivity data is available for each width setting in the product specifications.
