The JK Audio THAT-1 is a telephone audio interface that connects between the telephone receiver and base. THAT-1 is designed to capture audio to record and play sound bytes or to send IFB dialog over phone lines. The compact telephone tap features unbalanced RCA I/O.
The audio connections are used for sending line level signal down phone lines or capturing a mix of send and receive audio. Electret style handsets may be used with THAT-1 (carbon, dynamic or handsets with keypads are not compatible). A level adjust dial provides control over send and receive levels. THAT-1 is a compact, passive device that requires no external power source.
