Product Specifications

System Specifications

• Working Range:  91 m (300 ft) Line of Sight Note: Actual range depends on RF signal absorption, reflection and interference.
• Audio Frequency Response:  50 to 15,000 Hz Note: Dependent on microphone type
• Total Harmonic Distortion:  Ref. ±33 kHz deviation with 1 kHz tone 0.5%, typical
