Frequency Synthesized, Portable Wireless Microphone Transmitter in the 216 MHz Band 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.Features: High Fidelity Performance Adaptive Channel Selection Dual Function Versatility Specifications: Audio Input: Microphone input impedance for electret type microphone - 3k ohm Aux/Line input impedance - 10k ohm at 0 dB nominal Connector: Microphone - Micro-mini 2.5 mm mono (locking or non-locking) Auxiliary - Mini 3.5 mm Stereo - Audio - Tip and Sleeve - Battery Charging - Tip and Sleeve - External 9V power - Ring and Sleeve Controls and Indicators: Power On/Off switch Synthesized channel selection switches Microphone mute switch (Optional) Audio input gain control Modulation voice level indicator Antenna System: Body-worn microphone cord or whip antenna plugged directly into microphone connector when auxiliary input it used Frequency Response: 80 Hz to 10 kHz Modulation: 5 kHz deviation Ch. 1-40 (non-companded) 10 kHz deviation Ch. 41-60 companded RF Power Output: 10 mW to the antenna system Out-of-Band Emissions: Better than 45 dB below carrier Current Drain: 17 mA constant current Weight: 4 ounces (110 grams) Battery: 9 V alkaline for up to 35 hours of operation 9 V Nickel-Metal Hydride rechargeable for up to 15 hours of operation Dimensions: 1 1/6" x 2 1/2" x 3 1/4" (27 mm x 57 mm x 83 mm)
