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.
