Image Rejection

>70 dB, typical

Power Requirements

12–18 Vdc at 150 mA, supplied by external power supply

Operating Range Under Typical Conditions

100m (300 ft.)

Note: Actual range depends on RF signal absorption, reflection, and

interference

Audio Frequency Response (+/– 2 dB)

Minimum: 45 Hz

Maximum: 15 kHz

Note: Overall system frequency depends on microphone element.

Total Harmonic Distortion (ref. +/– 38 kHz deviation, 1 kHz tone)

0.5%, typical

Dynamic Range

>100 dB A-weighted

Transmitter Audio Polarity

Positive pressure on microphone diaphragm (or positive voltage applied

to tip of WA302 phone plug) produces positive voltage on pin 2 (with

respect to pin 3 of low impedance output) and the tip of the high

impedance 1/4-inch output.

Logic Connections (SLX4L only)

Absolute maximum -0.7 to 5.5V DC
Pin 2: Logic ground
Pin 3: Logic output, Battery Status. Good=low (0 V). Sinks up to 100 mA.

Absolute maximum -0.7 to 5.5V DC
