The AD903 has many functions for getting various levels of audio into an intercom circuit, or getting the intercom audio ¡°traffic¡¯ 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 ¡®Null¡± control allows you to minimize or even eliminate any ¡°cross-talk¡¯ 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.
