Special Features

The PCM SH-P1 is a digital audio processor that can convert analog audio signals into digital bit sequences, which can then be recorded onto a standard video cassette using a VCR.
Since the sound of non-HIFI recorders was relatively poor compared to other video formats due to the slow tape running speed, completely new sound worlds in digital stereo sound now became possible.
Whereas up to now the sound quality could get worse or better depending on the quality of the tape, it remains the same when using the PCM SH-P1.
Furthermore, any number of copies of a tape can be made without any loss of sound quality.
The PCM SH-P1 has the same design as the Technics pre- and power amplifiers SU-A2 and SE-A1. It is stackable with these components.
Any PCM-capable video recorder can be used as a recording device.
Remarkably, the actually poor longitudinal sound of a video cassette is maintained consistently brilliant when using the PCM SH-P1.
Every video recorder thus becomes a DAT recorder.
The only disadvantage to contemporary digital audio processors are the missing digital inputs and outputs.
The resolution of the coding is alternatively with 14 or 16 bit possible.
The sound is recorded on the video track. Therefore the PCM SH-P1 does not serve as a supplement for the sound, but turns every video recorder into a DAT recorder for high quality audio recordings.
