Design of dual channel at the same time using two hand-held (lavalier) wireless microphone without interference.

High-precision quartz lock a frequency.

Noise lock solve insurmountable noise interference problem of wireless receiver.

Ultra high sensitivity, highs/nratio, receiving range, continuous tone, not drift.

Built-in noise reduction compression-expansion circuit.

Superior selectivity, multiple channels at the same time, do not interfere with each other.

Metal housing, effectively avoiding disturbances.

Best suited for Studio/KarlaOK/broadcasting use.

Using the distance, ideal environment to50meters above, complex environments and practical RADIUS30-40metres.
