General
- Manufacturer: JVC
- Years of manufacture: 1970 - 1984
- Subject: JVC cassette deck technology
- JVC ANRS Automatic Noise Reduction System
ANRS
- ANRS was developed for quadrophony in 1970 (suppression of interference and noise- worked in the modulated difference signal) and was thus part of the demodulator circuit.
- As a spin-off then used for cassette devices as a noise suppressor as a direct competitor for Dolby B.
"Super ANRS
- With Super ANRS (compatible Dolby C) an improvement of the noise reduction at higher frequencies was done a little later.
In favour of Dolby C then approx. 1982 stopped
- Excerpt from advertisement: JVC ANRS
- Excerpt from brochure: JVC Super ANRS
- Besides the built-in circuits, there were 2 external units:
- 1972: JVC NR-1020 ANRS
- 1980: JVC NR-50 (ANRS, Super ANRS, Dolby B and C)
- Extract from brochure: JVC SEA-10 / JVC SEA-V 7E / JVC NR-1020
- Extract from brochure: JVC NR-50
