An address unit equipped with a 4-channel address circuit.
The AD-4 has 4 built-in address circuits, allowing simultaneous use of address for encoding and address for decoding. Therefore, when used with a 3-head deck, it is possible to simultaneously monitor the decoded signal while recording.
Since two decks can be connected, mutual dubbing between decks is possible without going through the address circuit. You can directly dub tapes with the address encoded signal or in normal mode.
