How do the decoders compare between the SQR-4750 & SQD-2020? If I remember correctly, the decoder on the receiver was also Full Wave Matching Logic.
Having just read the recent posts, the instruction manual to the European English/French/German SQD2010 states and I quote, Circuit system: "SQ decoder with front-back and waveform comparator logic circuits. Regualar matrix decoder."
This is the same description given in the manual for the SQD2020.
The difference is in the use of 4 ICs, 4FETs, 39 Transistors and 47 diodes as opposed to 69 transistors and 84 diodes.
Finally and in terms of sound, the later SQD2010 is superior to the SQD2020 being faster and quieter in operation.

Many thanks for your speedy reply, the idea of a Paramatrix is based upon communications technology and if it could have been made at a commercially viable price would have been quite something.
Here in England in the 1970s we did not even get treated to the Sony 4 channel receivers, or tuner-amplifiers as we called them at the time, let alone anything as advanced as a
parallel matrix board!
Best wishes.

Hi everyone and Merry Christmas. My wish for an SQD-2020 came true today. However, I seem to be having some trouble setting it up. I have two receivers a Sherwood-6108 (a surround receiver and a Fisher 4080 (4-channel) and after reading this post carefully about connecting the decoder, I attempted to utilize both receivers as front and rear. The Fisher does well as either a front or rear iwhen connected to auxillary but when it comes to the Sherwood, I don't know either to connect to tape, aux of one of the 6-channel inputs. If anyone can help or have any tips, I'd appreciate them. Other than the connection issue, the SQ decoding is a HUGE difference than the Fisher's odd internal SQ decoder as I've tested the rears with the Intro to the World of SQ Quad LP, Popular Science/Project 3 SQ Test LP, Switched On Bach and Music for Organ, Brass and Percussion by E Power Biggs.
Thanks in advance.
