There were three competing systems: QS (Sansui), SQ (Sony) and CD-4
(JVC). Only the CD-4, which used a supersonic subcarrier a la FM
broadcasting, required a special stylus on the cartridge (Shibata). Not
using this, would cause the supersonic information to be worn off after
a handful of plays. QS and SQ could be played on any standard stereo
phono cartridge, as they were reliant on out-of-phase information. The
Dynaco system used a resistor in the ground return of the rear speakers,
was the easiest to implement, and the hardest to encode. It was best
for enhancing stereo recordings.
Then there was reel-to-reel and 8-track tapes, neither of which were
popular. I think the idea of having four channels of amplification and
four speakers caused the consumer to put the brakes on the wallet, and
the lack of an FM broadcasting standard. I found the best way to sell
quad was to loan friends my SQ decoder, and a rear channel amp and
speakers. After they got used to the surrond sound, I thne took my
stuff back home. Going from stereo to quad was not a big difference,
but going from quad to stereo was a HUGE difference.

I don't do any recording, although, I do have
some very old records that
I've thought about copying to CD. I don't have a turn table that would
be handy, However :-(
Showing My Age Dept: Turntables seem to be more available now. I went out
to purchase one around '94 or so and at the first three stereo shops I
visited, the young person behind the counter said "You mean a record
player?? Why do you want one of those?" Sheesh.
What's the Joystick for?
Spacial control -- left, right, front and rear. This replaces the
two-directional balance control found on stereo amps.
In order to really use it, you have to be playing
a Quadraphonic
recorded record right? LP's were it back then, right?
Wrong. Some quad reel-to-reel tapes were produced. LPs were *mostly* it
-- Dark Side of the Moon was probably the biggest selling quad LP. The
opening "cash register" sounds on "Money" produced an excellent
effect.
There were at least two different quad formats. IIRC, one required
decoding in the hardware (my Fisher has an "SQ decoder" switch).
I'll bet it's next to impossible to find a working quad turntable these
days. I could convert some stereo recordings to "simulated" quad for
playback on a four-track cassette, but it would be more fun to find a
'table and some original quad records.
