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.
