THAT-1 - Telephone Handset Audio Tap
Connect THAT-1 between your telephone and handset for quick access to audio in and out of the telephone. The THAT-1 is used by radio stations to record and play sound bytes, and by computer and telephone companies to demonstrate their computer voice services using a powered speaker.
Record and Play Audio Clips
Simply unplug the handset coily cord from the base of your telephone and plug it directly into the THAT-1. Then, using the supplied cable, connect the THAT-1 back to the telephone. Now connect your audio equipment or powered speaker using the RCA jacks. The grey 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 RCA jack contains a nice mix of the audio from both sides of the conversation, as well as the tones being pressed on the keypad. The volume control adjusts the volume of the signal going to your powered speaker or tape recorder.
Phone Compatibility
The THAT-1 will work with many different types of analog and digital PBX and ISDN telephones. The receive side of the THAT-1 (audio From Phone), will work on any telephone. To send audio into the telephone (To Phone), the telephone must have an electret type microphone in the handset. If your telephone has a round mouthpiece, or if you intend to use this product on many different telephones, you should consider our model THAT-2 which is compatible with a variety of telephone systems. THAT-1 does not work with cordless or cell phones, or any telephone with a keypad in the handset.

- I have been using my THAT-1 for recording and it works great but when I try to send audio down the line it won’t work.
Several things could be causing this problem: First you must send a line level signal into the jack on THAT-1. Second, make sure the gray button is in the ‘In’ position. This disables the handset mic and enables the audio input. Third, the phone you are using must have an “electret” type mic in the handset. Not all phones are the same and THAT-1 is only compatible for sending audio with phones that have this microphone type. You may want to consider our THAT-2 which has a three position switch to allow you to use it with virtually any telephone. - Can I get an adapter that will allow me to connect THAT-1 to the wall jack instead of the phone?
No, your THAT-1 doesn’t replace your phone,, but works in conjunction with it. You will need to plug it in between the telephone base and the telephone handset. - Can I use THAT-1 with my speakerphone?
You cannot use the speakerphone function on your telephone and THAT-1 at the same time. THAT-1 accesses the audio through the handset cord. With the speakerphone turned on, most telephones disable the handset connection. Typically there is no audio going through the handset connection at the time. - What is the grey pushbutton on THAT-1 used for?
The button is used to select which audio signal will be sent into the telephone.
OUT = talking on the handset,
IN = sending audio through the RCA jack.
Keep in mind that you cannot send audio into the RCA jack and talk on the handset at the same time. However, any audio that is sent into the telephone can be heard on the handset and is available on the RCA output jack at all times. - We’re using THAT-1 to get caller audio to broadcast on our call in radio show. How do we get better sound quality?
THAT-1 was designed for only simple record and play applications. For better sound quality you should
consider getting a digital hybrid such as the Innkeeper PBX, Broadcast Host or Innkeeper 1rx.
