I don't have enough equipment to justify it, also it doesn't seem to come with the patch cords but I am sure someone here will be interested:

Bought mine from Gaylord Russell himself at '77 summer CES. It was a new product and the patch cords had to be shipped later. They are a 2-conductor mini plug on each end. Patch cords aren't needed for normal functions of the switchbox.

There are standard phono (RCA) jacks on the back panel.

I've had 4 main systems in those years and QT-1 has been attached to all of them.

A wonderful piece of gear, though a bit confusing to use at first.

Had one myself years back .

At the time I had quite a few decoders hooked up to it. These were:

Sony SQA-2030 (with the amp disconnected-straight decoding of SQ and RM )
Fosgate 101A(SQ)
Sansui QSD 2 (QS Vario matrix w/ Matrix H and HJ adapter)
Electro Voice EV 4 (EV-4)
Harmon Kardon 44+ (CD-4)
and my Superscope Q8 player , might have been hooked up as well or it was in my Sony preamp discrete jacks.


Anyways it was a versatile unit for anyone with multiple decoders/demodulators. So I would recommend it to any curious quadraphile that might be sitting on the fence. :)

Can one find a user manual for this and if the missing patch cords are not needed for ordinary use what then are they used for?

What do you mean by "Matrix H and HJ adapter" fizzy? The QSD-2 didn't handle Ambisonic natively, did you have one that was custom modified, or did you patch an Ambisonic decoder into the QSD somehow? You've got me curious!
I don't think Fizzy said anything about the QSD-2 handling ambisonic formats.
In decode (but not encode) terms the QS system was broadly the same as Matrix H and there was, very briefly, a modification for the QSD-2 made available for the UK market that allowed the QSD-2 to decode Matrix H. It was a simple mod that changed a couple of phase shift capacitors, sacrificing the Tape Monitor switch to enable the function. I don't think it worked very well and I imagine they didn't make many, and probably sold even fewer - especially as by the time the unit was available, the BBC were about to move on to Matrix HJ, and Sansui didn't move with them, rendering it all but useless.

Note that both H and HJ were quad systems , and not ambisonic. Ambisonic designated UHJ , came about sometime later in the 70's probably 79 , but that's a good guess.

It should be mentioned that Quad matrix HJ was a compromise of BBC QUAD MATRIX H and the NRDC'S 45J (the early ambisonic system of .).

HJ was compatible with BBC MATRIX H and 45 J.

Not a problem with playback in my quad system utilizing the QT 1, as the adapter was hooked up to my QSD-2.

You should check out those threads (must be 3 or 4 perhaps) located in the" matrix quad legacy" area .( The ones that mention quad matrix BBC MATRIX H and BBC MATRIX HJ).
(there is also a thread on matrix h in the ambisonic section, which does not belong there , but that's up to the moderator to correct )
There are some Integrex decoder pictures relevant to the matrices in practice back then and they utilized H and HJ along with SQ and RM , and should even be some other decoders of note, (eg; Comcor , Sansui, . .....)
Always wanted one of those years ago , but near impossible getting them across the pond.


Lots of very relevant matrix quad info there for anyone still interested in matrix quad . :)
