                      for a single system

NOTE: Actual working range depends on RF signal absorption, reflection and interference

Audio Frequency Response

      40 – 18,000 Hz,(+1 dB, –3 dB).

NOTE: Overall system frequency response depends on the microphone element

Gain Adjustment Range

      –10 to +20 dB

Modulation

      FM (45 kHz max. deviation), compander system with pre- and de-emphasis

RF Power Output

      10 / 50 mW

Dynamic Range

      >105 dB, A-weighted

Signal Polarity

      Positive pressure on microphone diaphragm produces positive voltage on XLR output pin 2 with respect to XLR pin 3 and on the tip of the 1/4-inch output jack.

System Distortion (ref. ± 45 kHz deviation, 1 kHz modulation)

      <0.3% Total Harmonic Distortion typical

Power Requirements

      Two 1.5V AA batteries

Current Drain

      180 mA max. (normal RF power setting)

                      240 mA max. (high RF power setting)

Battery Life (Typical)

      9.5 hours (low power)

              6 hours (high power)

Operating Temperature Range

      –18° to +57° C (0° to +135° F)

NOTE: Battery characteristics may limit this range

NOTE: Electrical safety approval is based on a maximum ambient temperature of 35°C (95°F).
