Dolby B-C Type Noise Reduction System (1981)
The Nakamichi NR-200 incorporates the revolutionary Dolby-C noise reduction system (C-Type NR) developed by Dolby Laboratories, as well as the Dolby-B noise reduction system (B-Type NR) which has been featured in many cassette decks so far.
As against the 10dB of high frequency S/N improvement afforded by the B-Type NR, the C-Type NR achieves 20dB with virtually non-existent sound colouration.
Simultaneous record/playback with 3-head tape decks is easily possible, because noise reduction circuits are used for encoding (recording) and decoding (playback).
