Pre-Assembled Module or Self-Assembly Electronic Kit (Soldering Required)
TheTelephone Recording Interface is used to automatically record all conversations that take place on the target phone line to a tape recorder (not supplied). It only operates the tape machine while the phone is in use so no tape is wasted or left blank.
The TRI is connected in parallel with the phone line and to the any tape recorder's REMOTE (see note below) and MIC sockets. The TRI can also be used with voice activated tape recorders/personal dictation machines. These only need to have a MIC socket as the voice activation circuitry will automatically start and stop the recorder as the phone is used.
The TRI will operate recorders with 1.5-12V battery systems and it also has an onboard polarity switch so that it can be used with either positive or negative wired REMOTE sockets.
