    BLX288 Dual Wireless Receiver
  • Working Range: 91m (300') Line of Sight
    Note: Actual range depends on RF signal absorption, reflection and interference.
  • Audio Frequency Response: 50Hz - 15,000Hz
    Note: Dependent on microphone type.
  • Total Harmonic Distortion: Ref. ±33kHz deviation with 1kHz tone: 0.5%, typical.
  • Dynamic Range: 100dB, A-weighted, typical
  • Operating Temperature: 0°F - 135°F (-18°C - 57°C) Note: Battery characteristics may limit this range
  • 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 ¼-inch output
    Note: All Specifications are subject to change. Performance may vary depending on country regulations and operating environment.
