Mounting Guidelines

The sensing microphone must be mounted at the same height as the loud-

speakers or higher. A sensing microphone must never be mounted lower than

the loudspeaker height.

In all cases, there must be 6 ft (1.8 m), minimum, between the loudspeaker

and the sensing microphone. This is so that the microphone does not receive

signals only from a loudspeaker.

There must be 35 ft (10.7 m), minimum, between the sensing microphones of

two adjacent Auto Volume zones.

Avoid placing the microphone near unique noise sources like HVAC equip-

ment, dishwashers, motors, etc.

Note: See "Designing with the FreeSpace 4400 System" in the FreeSpace

4400 Business Music System Owner's Guide for more details on sensing

microphone placement.
