The M-216
wireless microphone transmitter offers the ultimate performance and versatility
for assistive listening, language interpretation, tour guide presentations,
personal cueing, and for other personal remote transmission situations.
For use with the PR-216 and PR-216 Option 7 synthesized receivers.
The M-216
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 from a wireless microphone.
The transmitter's
microcontroller automatically sets the modulation deviation, companding
or non-companding audio processing, and the EQ when corresponding channels
are selected. Because of this comprehensive feature, this versatile transmitter
can transmit on 19 high fidelity channels and 38 standard channels ensuring
compatibility with receivers conforming to regulations regarding Low Power
Radio Service (LPRS) transmissions in the 216-217 MHz band under Part
95 of the FCC regulations.
