Remote Program Monitoring • Personal Cueing • Wireless Tour Guide • Assistive Listening



• High Fidelity Performance
• Adaptive Channel Selection
• Dual Function Versatility

The M-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. The transmitter’s microcontroller automatically sets the modulation for companding or non-companding audio processing when the corresponding channels are selected. The channel selection also sets either narrow-band operation on channels 1-40 (5 kHz deviation) or high-fidelity, wide-band operation on channels 41-60 (10 kHz deviation). The optional microphone mute switch turns off the microphone without turning off the aux input.
