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

The frequency range is UHF520-930MHz, which avoids interference frequencies and is convenient to use.

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.

Multiple static noise control circuit, rejecting external interference.

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

The LCD display screen can simultaneously display the channel number and operating frequency.

Frequency range: UHF520-930MHz.
