Notes

The NAGRA PS-1 is a highly sophisticated playback system designed in 1984 to read JBR's special miniature cassettes recorded on the stereo spy Nagra JBR recorder.

JBR recorder has no playback  system and one adaptor for NAGRA SN spy recorder was used between 1984 and 1986. Nagra JBR and PS-1 were exclusively produced for USA security agencies but  some Canadian and British securities agencies  have access to the recorder and playback system.

PS-1 corrects speed fluctuations, expands the signal compressed when recording, and offers fast forward and rewind functions for the easy location of a particular recording.

Separate adjustable filters allow fine tuning of each audio channel to fit curves displayed on the machine itself. The PS-1 is also provided with an adjustable expansion ratio, with a real time counter, with automatic counter reset, go to functions, etc.

Frequency response: 170 Hz to 4700 Hz. In the JBR tapes a signal with the frequency  of 5461 Hz is recorded for speed correction purposes and the audio bandwidth is limited to 4.7 kHz.

In PS-1 a  numerical keyboard for sophisticated commands is located under a small cover, in order to avoid unintentional use. The output signal is fed either to headphones, built-in loudspeakers or line.

The PS-1 operates either on internal batteries, external 12 V DC or 220/110 V AC.
