Quadraphonic records (LPs to you and me)


If normal analogue comes through as 2 channel, what effect does a quadraphonic record have?
If my processor (Bryston sp3) codes 2 channel into surround 7.1 - which it does exceedingly well- does that make the separation easier?
(Bryston do not know)
Thanks chaps and chapesses

It isn’t clear what you mean by "normal analog." Analog can be any number of channels. Two-channel stereo is just one configuration.

In any event, a quadraphonic record can store four channels, which you can feed to a quadraphonic system using a proper phono cartridge and phono preamplifier.

You Bryston has nothing to do with Quadraphonic Descrete-4 records. In fact your Bryston designed for Digital Audio (Dolby Surround) in Home Theater application. 

To play records you need just normal stereo (Left and Right channel). 

Quadraphonic Records (Descrete-4 or CD-4) require special cartridge and special processor, also 4 speakers. You can learn more about it here https://en.wikipedia.org/wiki/Compatible_Discrete_4

CD-4 was only one of the quad LP formats, although I think it may have been the only discrete format for LP.  SQ and QS were competing formats to put quadraphonic audio on LP.
