General Description
The Model 1200 receiver/ amplifier will receive
a digital audio signal that is being transmitted in
the 2.4 GHz range by either the Model 1000 or
Model 2000 transmitter. The recovered audio
signal will pass a digital as well as an analog
filter stage to eliminate out-of-band components
and is amplified to the maximum output power
of 200 W to drive a speaker unit.

By receiving the signal in a digital format, noise
and quality losses that are inherent with
conventional analog systems are avoided.
