• Several units can be daisy-chained
Sound
Processing
Processor controlled automatic mixer with eight bal-
anced microphone inputs and one master output.
A unique APG (Adaptive Proportional Gain) algorithm auto-
matically allocates gain among the system microphones.
An Adaptive Skewing function keeps non-speech sounds
(coughs, bumps, clicks and pops) from affecting the auto-
matic mixing functions. A compressor/leveler is included
in the algorithm to compensate for level differences and
provide a significant improvement in sound quality. Input
and output levels, Auto/Direct mode, and compressor/lev-
eler threshold can be remote controlled from a PC or other
RS 232 compatible control system, e.g., Crestron
®
or
AMX™.
The AS 8 is the basic version. The AS 8 TC provides addi-
tional, separate bass and treble controls for each channel.
