Features:

Using quartz oscillation circuit, high frequency stability.

The audio compression - extension technology, greatly reduce noise, dynamic range.

There is the function of doping call down less, can effectively reduce the lost call back.

Receiver using multilevel high frequency amplifier has a very high degree of sensitivity.

Noise level locking double mute control, noninterference more machine used at the same time.

Has a balance and imbalance way audio output.

Wide frequency response range, low distortion.
