In Reply to: Sansui QS-1 Quad rear amplifier posted by djgaloot on July 14, 2009 at 15:17:00:
that's about it for functionality. Sansui promoted the QS encode/decode system (as opposed to SQ and CD-4) which was much like SQ in that it was a matrixed synthesis of 4 channels into 2 channels.
What's interesting about this one is that there's no mention of QS that I can see. In that case, that would make this dematrix unit an early implementation.
Most of the players in the 4-channel craze in the 70s marketed all sorts of add-on devices to retrofit 2 channel systems into 4-channel. This model seems to attempt to replace all the controls you had to dink around with by replicating them in one box. Nice idea but most, indeed, did also supply the additional 2 power amp channels.
I've posted here before about why 4-channel died a merciful death mostly due to the complexity of operating the darn things.
Cheers,
David
