Frequency Synthesized, Base Station Transmitter

The BST 25-216 transmitter incorporates the latest digital and analog technologies to produce low residual noise, wide dynamic range, and extended frequency response rendering the most natural sound possible for a wireless system. For highest fidelity operation, the PR-216 receiver can be used on the wide-band companded channels. The BST 25-216 is also compatible with other manufacturer's all-in-ear type receivers operating in the 216-217 MHz band on the narrow band non-coompanded channels with a special EQ setting. The transmitter's microcontroller automatically sets the modulation deviation and the audio mode for companding processing when corresponding channels are selected.
