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