Beautiful piece of gear BBQ.

I’ve got some thoughts/questions about this one (don’t remember seeing one before); I’m assuming the R-MTX is for RM?

Also, the Discrete is mainly for R2R?

And the 2->4 button does what/which system?

Hi. Pupster
Your assumptions are correct and the 2->4 button is stereo in front and in the back channels 2 lots of stereo.
even if you don't use it to decode SQ you can use its 4 meters for a 4ch input..

It would be a dream (and perhaps not too difficult) to be able to put a Surround Master inside of this beautiful box and arrange for most of the buttons, knobs AND METERS! to do what they are meant for.

That's exactly what @par4ken did with his Sony SQD-2020. He used the SM v1.

Would love to see the entrails of that!

Wait, so you'd strip out the vintage electronics? Ick.

More like a symbiosis...

And anyway, after the SM all other options are way, way more troublesome and risky, not to mention low-performing.

I belive what Ken did was use the SM demo board (QS only) installed internally & hooked the outputs to the discrete inputs on the 2020. Nothing stripped out just added.

Edit: To @par4ken do you have any "synthesis" out of phase blending on your 2020 box for QS?

 

[ubertrout]

I don't mess around with quad-era stuff, so I'm sure you're right. But my gut is that modifying the old stuff is going to seem like a terrible idea if you fast forward a few years.

I put the Involve evaluation module inside the Sony box mounted below the main board. I Also added a 9 Volt power supply (silver box) to power the module. The input jacks are wired to the Involve inputs, via a short, cut length of RCA plug cable. The outputs are wired to the discrete input jacks in the same manner.

Originally I had the QS board installed, then I could instantly compare it to the RM function of the Sony unit. Now I have the SQ board installed, it can instantly be compared to the Sony decoder. Input level pot on the rear panel can be adjusted to match the level from the Sony decoder with the Involve one. Full functionality of the Sony unit is maintained with the exception of the discrete input. If needed you can still use the tape input.

Beautiful, Pak4ken!!!

The Surround Master v2 puts these old boys to shame sound wise, but oh those VU meters on the SQD-2010 and 2020!

Now you've triggered the Beatles lyric "Lovely Rita, meter maid" flowing in my head (sadly in mono!)

Many people will swap pieces of gear in & out of their audio systems. You switch out internal PC boards. You da man!

My favorite song on the album. To me, it epitomizes the Beatles' sound of that era better than any other song.

Great job!!!!!!!!!!!!

 

[Obbop]

Dagnabbit . . . and I have a tough time replacing that dern' 9-volt battery in the smoke detector and you youngungs are fiddlin' with the innards of that highfalutin electronical equipment thingamajigs!!!!

 

[Wagonmaster_91]

I run my SM through the discrete inputs of my 2020. That way I can use the meters as well as any of the functions of 2020.

Beautiful, Pak4ken!!!

yeah, great! It has to suit your needs!
Which SQ circuit did you use? I see the 3 Motorola chipset?
Which CD-4 is in this Sony implementet? with the both 28pin 5022/ECG815 or single transistors?
(I still have to do a lot with mine ...)
