Shure SLX14/WH30 Headworn Wireless System Details

• 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
  (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
• Operating Temperature Range
  –18°C (0°F) to +57°C (+135°F)
  Note: battery characteristics may limit this range
• 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.
