Connect the JK Audio THAT-2 between your telephone and handset for quick access to audio in and out of the telephone. The JK Audio THAT-2 is used by radio stations to record and play sound bytes and by TV and film sound crews to get IFB dialog over phone lines. The THAT-2 is a passive handset interface which has professional and consumer jacks, separate input and output volume control, a selector switch for different types of telephone systems and still does not need any batteries or AC.
Simply unplug the handset coily cord form the base of your telephone and plug it directly into the THAT-2. Then, using the supplied cable, connect the THAT-2 back to the telephone. It connects your audio equipment or powered speaker to the RCA or XLR jacks. The Gray pushbutton selects which audio will be sent into the telephone (OUT = talking on the handset, IN = sending audio in through the RCA jack). The output jacks contain a nice mix of the audio from both sides of the conversation, as well as the tones being pressed on the keypad.
It has a three-position switch which accommodates electret, dynamic and carbon telephone handset microphone types. The THAT-2 will emulate the type of microphone that is in the handset and allow you to send audio into many different types of analog and digital PBX sets, as well as ISDN telephones. The THAT-2 does not work with cordless or cell phones or any telephone with a keypad in the handset.
