Models of PCM Adaptors
The Sony PCM-1600 was the first commercial video-based 16-bit recorder (using a special U-matic VCR for a transport), and continues in its 1610 and 1630 incarnations. The 1600 was one of the first systems used for mastering audio compact discs in the early 1980s by many major record labels.
Several semi-professional/consumer models of PCM adaptor were also released by Sony, including:
- Sony Digital Audio Processor PCM-F10 (the first consumer-marketed model),
- Sony Digital Audio Processor PCM-F1 (which was sold with a companion Betamax-format VCR, the Sony SL-2000 or SL-F1, for recording & playback).
- Sony Digital Audio Processor PCM-100,
- SONY Digital Audio Processor PCM-501ES,
- Sony Digital Audio Processor PCM-601,
- Sony Digital Audio Processor PCM-701.
Technics also made a portable PCM adaptor as well, the SV-100, and a version with a built-in VHS videocassette transport, the SV-P100. Nakamichi as well manufactured a PCM adaptor, the DMP-100.
dbx, Inc. also manufactured a PCM adaptor, the Model 700. It differed from the above listed models in the fact that it did not use PCM, but rather delta-sigma modulation. This resulted in a higher quality digital recording with more dynamic range than what standard PCM modulation could offer. Like a standard PCM adaptor, the Model 700 also utilized a VCR for a transport.

“Today it is not the classroom nor the classics which are the repositories of models of eloquence, but the ad agencies.”
—Marshall McLuhan (1911–1980)
“The greatest and truest models for all orators ... is Demosthenes. One who has not studied deeply and constantly all the great speeches of the great Athenian, is not prepared to speak in public. Only as the constant companion of Demosthenes, Burke, Fox, Canning and Webster, can we hope to become orators.”
—Woodrow Wilson (1856–1924)
