New Surround Master coming! Its a jump to the left and a step to the right

Chucky: How is input level managed in the V1?

John R

As we are controlling the overall volume of 6 channels we would need to use a digital 6 way volume control chip to do it in the output lines. We have used these chips before but in this instance we do not think it is warranted for cost and they tend to have 1 db steps. As I am trying to maintain as much "analogue" as possible we are making it a input overall level adjust (dual gang pot), we are also now including a clip LED so it has the benefit of maximising dynamic range.

The LFE output is active in all modes except stereo pass through.

Hey Chuckie: Thanx much for your reply. Now just when will you be sending my free sample, soon?

Only one?

Its not.....just straight through

I don't know what I'm talking about in terms of cause and effect, but could there be an upgrade option to incorporate the highest quality capacitors(Elna Silmic) and any other important electronics in the signal path? I took care/expense to have that done while my Marantz 4300 recapped. I intend to also upgrade my Oppo 105 power supply which includes ES cap upgrades.

I like to spend money on things I don't understand, based on others' superior knowledge, and then see if an overall sound improvement is realized. It has been fun, informative and successful.

Since others may have much higher fidelity systems than my own, upgraded electronic components may pay off?

Upsell me!

Since Involve seems to be one of the very few companies that actually listen to input during the design process, I'll put in my 2 bits.
The only thing I can suggest for the SM V2 is a stereo synthesizer mode as was done on Sansui decoders. This is just a bit of out of phase (or opposite polarity if you prefer) mixing between input channels. Officially this would be at .414 but in actual measurements I've made on Sansui decoders this was closer to .316. I've come to the conclusion this was done in anticipation of having a certain amount of out of phase content present in the stereo source.

Doing this is incredibly easy to do and would allow the SM to pan a sound around 270 deg when the stereo signal pans left or right. That effect of having solid left/right rears adds much to the effect.

I asked Charlie about that when he first made the Surround Master
like the QSD1 had
He did not seem to interested

The reason I was / am not particularly interested is that any successful universal stereo / surround upgrade system must be a set and forget and avoid bunk that is on modern "receivers" ....hall mode, theatre mode etc. I claim the psychoacoustic stuff we bolted onto the initial Sansui QS concept actually enhances the surround extraction you get, even from non encoded sources.

We reluctantly made a special SQ edition of the Surround Master decidated to all the one eyed extremists for this great forum. Our reluctance was that the SM was no longer a set and forget product.

We are reviewing all capacitors, avoiding ceramics where possible. We are also going to a 4 layer PCB to improve grounding and shielding.

Did I mention steak knives and it comes with a 3 inch penis extension?

Great! I could sure use the steak knives.

 

[Simon A]

In my humble opinion, you should not include the knives and the extension as to many people would poke an eye out with them thangs...

The V2 will be great as you've designed it.

 

[surround.sound.enthusiast]

Indeed, steak knives... great!! If you might remember, back in the 70's you could slowly build up a set of them from gas (petrol) stations here in the U.S. with each fill-up. That fits right in-line with the whole "70's" and "quadraphonic" thing going on here...

 

[chucky3042]

Actually the new design gets rid of 8 capacitors!!

Mono compatibility was a major issue back in the (Quad) day
(there's still 1 mono clear channel AM music radio station here).

SQ was said to have good mono compatibility (LF,RF,LB,RB all combined with
no amplitude loss) whereas QS (LB,RB) suffered about an 8dB loss in mono.

What's the mono compatibility of the Involve Matrix encoding?

Good Question....err actually I forgot, so I measured a SM to find out.

For a mono Right input if you nominate the right output as 0 dB then the left is 14 dB down on right

If you input the same in phase signal into Left and Right the Left and Right outputs are +3dB HIGHER each

Hope that's as clear as mud

There is no need to delete this!

well he's entitled to his opinion, even if it's not one shared by some of us and other Quaddies elsewhere.

i'm not sure where Dutton Vocalion said the Airto/Deodato Live album on their 2-fer SACD was discrete? pretty sure on the disc packaging and on their website they said it was decoded? afaik the Airto/Fingers studio album on that 2-fer is discrete from the 4-ch masters and Airto/Deodato Live is not.

it is a shame he gets so heated about stuff sometimes and he showed his explosive side on QQ a few times over the years but he is passionate about Quad and doesn't do things by half measures, can't take that away from the guy.

i don't agree the SM is a "useless piece of plastic", a "piece of crap" and a "bloody awful box" but that's just one person's view and again if that's what he thinks well that's upto him.

its kinda sad people here are described as "QQ nobodys" but if that's how he feels well, again, imho that's upto him too! i'm sure we all have thicker skins and can let it go.

could be..! or maybe they tried it and just didn't care for it! its not for everyone.. it screams Watford not Oxford!
