The JBR Microcassette Playback/Transcriber Unit was specifically designed to "safely" and "accurately" play all known ¼ track stereo and ½-track monaural micro-cassette recordings.

Transcription - In addition, the unit has a foot pedal to control the Play, Stop, and Backspace; a variable speed control and multiple headphone outputs to aid in efficiently and accurately transcribing hard-to-understand covert recordings.

Copying/Duplication - Adding a standard cassette dual-deck recorder and the optional duplication control unit, creates a professional quality micro-cassette-to-standard cassette duplicator. Adding a CD-Recorder in addition to or in place of the cassette recorder creates a micro-cassette-to-CD-R duplicator.

Special Features - The JBR Micro-cassette playback unit has two playback heads. The right head is located in the standard position. The left head is located 3/4 of an inch before the standard head location. Therefore, this head plays approximately 3/4 inch of virgin tape, then the original record head start transient, followed by the original erase head start transient and the exact point where the audio starts being recorded on the tape. This set of data is crucial in determining if a tape recording is authentic or had been changed or altered. No other known micro-cassette playback unit can recover this set of data.
