## Description

The AD903 has many functions for getting various levels of audio into an intercom circuit, or getting the intercom audio &#xA1;&#xB0;traffic&#xA1;&#xAF; out to an amplifier or recorder. It is also useful as a 2-to-4 wire adaptor for connecting 4-wire communications into and out of a standard intercom circuit. The &#xA1;Null&#xA1;&#xB1; control allows you to minimize or even eliminate any &#xA1;&#xB0;cross-talk&#xA1;&#xAF; between the input and output. The input transformer is a studio grade device and will not degrade any audio that you feed it. The AD903 is also commonly used for connecting to a video camera CCU where a built-in intercom is provided that is not compatible with Pro Intercom or any of the other 200 Ohm unbalanced intercom systems.

## Features

- The AD903 is powered by the intercom system and requires no batteries or separate power supply.
- The AD903 connects to the intercom circuit just as a beltpack does, through a rear panel 3-pin XLR.
- Access to the input and output are via a rear panel 4-pin XLR. Pins 1 and 2 are input and pins 3 and 4 are output.
- Both the input and the output are transformer isolated from whatever devices are connected. The wide range of level adjustments will accommodate almost any audio signal.
