Hahahahaha :) I'll keep it brief, and just for the record I'm no expert on
the subject.
Quadraphonic is nothing new, even when it first appeared in commercial hi-fi
back in the early 70's.
There were a number of systems. Amongst the most predominant were -
CD-4 or discrete 4 channel. Also known as QuadraDisc.
In this system the front channels were normal analogue L and R modulations
in the record groove. The rear L and R channels were modulated with a 30kHz
carrier. A special CD-4 capable cartridge equipped with a Shibata or
similar profile stylus was required to track the high frequency modulations
of the rear channels which had frequencies as high as 45kHz. A CD-4
demodulator processed the front channels as normal RIAA equalisation, whilst
the rear channels had to be demodulated back down to audio to be heard. The
system wasn't fully compatible with existing 2 channel playback equipment
but did give the best separation.
SQ - a matrix system developed by CBS and Sony.
Like most matrix systems this relies on taking 4 discrete channels and
encoding them into 2 channels.
The SQ system encodes the 4 channels in the following way -
The L encoded or "total" channel is composed of the original L front channel
information unaltered to which reduced amounts of the two rear channels are
added with their phases altered.
The R "total" channel has the R front channel unaltered to which reduced
amounts of the rear channels are added with their phases shifted with
relation to the rear channel signals in the L "total" channel.
Mathematically they can be expressed as L(total) = L front - j0.707L back +
0.707 R back and,
R(total) = R front +j0.707R back - 0.707L back.
The advantage of the matrix systems is that unlike CD-4, a conventional
cartridge and stylus could be used to playback the records. An SQ decoder
separated out the 4 channels, but separation was never as good as the CD-4
system. However, unlike the CD-4 system, if a matrix record was played back
on a conventional 2 channel stereo system no information was lost.
Disadvantages were not as much separation between channels as the CD-4
system. However as the technology evolved, logic enhanced SQ decoders
improved in performance. Of the most sought after are the Tate 101 which
could reputedly resolve a 30dB separation between channels. On a more
practical note the later Sony models (eg. the SQD-2010) resolved as much
separation as -
Lf - Rf 35dB
Lb - Rb 13dB
Lf - Lb; Rf - Rb; Lf - Rb; Rf - Lb 17dB
QS or Regular Matrix (Sansui and some others)
Similar to the SQ system but not as sophisticated.
To playback quadraphonic records all one needs is a suitable decoder and a
multi-channel amplifier + 4 speakers.
I have stuck to the SQ and QS matrix systems for the following reasons -
Conventional cartridge and stylus.
Got a Sony SQD-2010 decoder which decodes SQ and QS records.
Integrates easily with my existing multi-channel system.
Matrix quad records can be directly transcribed to digital media which
preserves the encoding, so playback through the decoder gives just as good a
result as playback from the record.
There are lots of matrix quad records out there you can still purchase
second-hand and if you are lucky enough as new and sealed pressings.
Some SQ encoded CDs exist although you'll hardly ever see it noted on the
covers. Pink Floyd's Machine Head 25th Anniversary Edition has 2 tracks
which are SQ quad encoded (says so on the cover). Others include Santana's
live album Lotus. etc, etc.....
Cheers,
Alan
