Using UHF550-980MHz frequency band, the PLL frequency synthesis phase-locked loop technology is applied, the frequency is adjustable, the transmission power is adjustable, and the interference frequency is avoided.

Integrated bus control of the central processing unit CPU, with digital LCD interface display, easy to operate, outstanding performance.

The multi-stage narrow-band high-frequency and intermediate-frequency selective frequency filtering is adopted to fully eliminate the interference signal.

With audio compression and expansion technology, the noise is greatly reduced and the dynamic range is increased.

It has a function of reducing the howling suppression and reducing the whistle.

The receiver uses multi-stage high-frequency amplification for extremely high sensitivity.

Multiple noise monitoring circuits with a unique tone-locked TONE-LOCK system for unmatched immunity.

The excellent sound quality is achieved by using excellent chips and high-quality components.

The wide and wide use range is more than 100 meters, and the ideal open space is 50 meters.
