Full description

Delta-modulation and clear audio reception

ENPRK-040D is a multichannel UHF receiver for compatible audio transmitters using delta modulation. It also receives clear WFM signals in the 416–421 MHz band.

Up to 10 channels can be stored and recalled with the channel selector. The transmitter and receiver must use matching frequencies, modulation and delta-modulation settings for the intended audio link.

Audio controls and power options

The volume control incorporates the power on/off switch. A channel selector and line LED indicator complete the main controls. A headphone output supports direct monitoring. The recorder output includes a remote-control function for a compatible external recorder.

The receiver operates from a 6–9 V external supply or three AAA 1.5 V batteries. Current draw at medium volume is no more than 50 mA.
