SPECIFICATIONS

System

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
