adjustment is +20dB, but will adjust only +6dB. Adjustments will not be made at

.5dB on either side of the target (0dB).

High Pass Filter

A high-pass filter can be selected on each gated input to reduce unwanted noise. The filter has a break frequency at 250Hz, suppresses the signal 3dB at 200Hz, then rolls off at 6dB per octave below 200Hz. This feature is disabled when shipped from the factory.

Three-Band EQ

A three-band graphic equalizer can be selected for each input for matching dissimilar microphones and for general circuit tuning. This EQ circuit provides 12dB of cut or boost, centered at frequencies of 250Hz, 1kHz and 4kHz, Q factor of 1.4. This feature is disabled when shipped from the factory.

Chairman Mic

Each input can be selected as the chairman override microphone, allowing the chairman’s microphone to gate on, regardless of which other microphones can be on. As shipped from the factory, chairman mic is disabled. This feature can have a single microphone selected or a group of microphones selected.

Adaptive Ambient

The adaptive ambient mode can be turned on (default) and off. The recommended setting is on. However, if the ambient noise in the room is constantly changing and the AP800 is unable to track properly (see Figure 2.14), turn this mode off and set the ambient level manually (see Manual Ambient, page 19). Fixed values range from 0dB to -70dB, in increments of 1dB.
