The Tecpro studio grade AD903 converter has various functions for getting levels of audio into an intercom circuit, or getting the intercom audio “traffic’ out to an amplifier or recorder.

This converter is also useful as a 2-to-4 wire adaptor for connecting 4-wire comms into and out of a standard intercom circuit. The AD903 connects to the intercom circuit just as a beltpack does, through a rear panel 3-pin XLR.

Both the input and the output are transformer isolated from the designated devices that are connected. The wide range of level adjustments will accommodate most audio signals. The AD903 is powered by the intercom system therefore requires no batteries or separate power supply.

The AD903 converter comes in protective case and is supplied with a YL908 Y-lead.
