Optonica amplifier (SM-3636) and tuner (ST-3636) from 1978. The Optonica brand was created and first launched by Sharp of Japan in 1975 to compete in the high-end audio market along with established brands such as Sansui Electric, Sony, Panasonic, Sanyo, Yamaha, Nakamichi, Onkyo, Fisher Electronics, Technics (brand), Pioneer Corporation, Kenwood Corporation, JVC, Harman Kardon and Marantz.
In 1973, Sansui introduced the more advanced QS Vario Matrix decoder with 20 dB separation. The SQ system developed by Columbia/CBS was the most popular matrix system. But later QS decoders could also play SQ records. Some Sansui receivers could also play the most advanced four-channel system: CD-4 (or Quadradisc) by Japanese JVC and American RCA.
The ratio of power of the analog signal to the digital signal was initially standardized at 100:1 (−20 dBc), i.e., the digital signal power is 1% of the analog carrier power. This low power, plus the uniform, noise-like nature of the digital modulation, is what reduces its potential for co-channel interference with distant analog stations.
