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.
The Model 1200 receiver/ amplifier will apply
forward error correction to the received signal in
order to maximize reception robustness.
The amplifier is a digital (class D) amplifier. The
typical power efficiency is 90 %.
The Model 1200 receiver/ amplifier will enter a
Power-Down Mode if no valid signal is received.
It will return to active mode when a valid signal
is detected.
