Automatic frequency scan.

The receiver employs a EIA international standard 1 U 19" cabinet. It can be installed into a standard equipment rack with its equipped nylon ears.

If connects to an antenna distribution system, the microphones can achieve longer receiving distance and more stable performance. Ideal working distance can be up to 300m.

VA LCD screen fully displays channels, frequency, RF signal status, AF udio output status, scan status etc.

Worldwide certified 12V/1A  power supply.

UHF PLL synthesized oscillation mode and 25MHz channel interval.

Four antenna with auto frequency selection, dual mute and voice code locking loop circuitry ensures stable performance even working in long distance.

The built in SQ circuitry avoids interference noise output without decreasing the Q value or sensitivity under disturbing environment.

Customized frequency range setting.
