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.
Woa! Best selling? The copy I have is the only other one
I've ever been aware of! Now I know of two....
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.
The British import copy of Electric Ladyland says it's stereo,
but it is in fact SQ-encoded; listen to Jimi's guitar swirl
around all four speakers on "And the Gods made Love".
