Use the UHF520-930MHz frequency band to avoid interference frequencies.

Flexible and easy to operate.

Fully automatic infrared frequency matching enables the transmitter and receiver to automatically synchronize transmission and reception.

Adopting a phase-locked loop (PLL) frequency synthesis stabilization system, providing 200 channels.

Adopting the latest high-frequency filter to filter out out out of band interference signals to the maximum extent possible.

Adopting a high-frequency circuit design with secondary frequency conversion, it has extremely high sensitivity.

Specially designed speech compression and expansion circuit greatly improves signal-to-noise ratio.
