I am interested in learning more about Quadraphonic stereos and it's music.
Stereos usually had 2 speakers.
But if the stereo had four speakers or more, did that makes it Quadraphonic?
To know if the stereo was Quadraphonic, must the word Quadraphonic be
mention in the manual? -Describing it as a Quadraphonic Receiver?
And what about Quadraphonic music being broadcast from the radio? How
did that worked?
Does Joe Franklyn, Danny Styles, Symphony Sid or Phil Shapp plays any of
this?
Ah those beautiful stereos with silver faces, needle light and silky
turner. Those were the days!

I seem to recall quadraphonic LPs came and went in a year or two in
the Seventies. No one could figure out what to put in the rear
speakers. It didn't make sense to be sitting in the middle of a band,
sound-wise.

Quad LPs (CD-4) were around for a while, but the front/back
information was encoded as an ultrasonic subcarrier, and a special
needle was needed. IIRC, a regular needle would destroy a CD-4 disc.
As for the encoding techniques, there was SQ, QS, logic-enhanced
variants... a childhood friend's parents had a full quad receiver with
all the various settings to cope with the formats. WCLV, Cleveland,
broadcast in quad for a while, and, I think, in Dolby-FM.
Some of the higher end audio shops in Cleveland ran quad ads on WCLV:
"Now I'm in front of you. Now I'm behind you. To your left, and to
your right. If you are listening on a regular stereo, you heard left,
right, left, right. We at Audio Craft can show you how quadraphonic
stereo can enhance your listening experience..."
