Hey surround team
The preamp will probably be sent for the for prototype manufacture next week, here is an actual snapshot of the final layout, for ACDC fans there is a hidden prize!

If you note that there is provision for two different package CPU'S that's because of the current Chinese component shortages- so we can substitute if need be to a through hole alternative.

You might think that it does not look that complicated- well there are 555 components on the board and around 600 when you include the front PCB and the Bluetooth module!!
ADC...DAC....?

You like to torture don’t ya!

I thought maybe you’d hidden an AC/DC song on one of the chips, so when you fire up the unit it plays this…


or if you prefer the Bon years


Alright then, carry on.

Dear All

Bad and worse news

Dave the Bitch is currently very horizontal with the blessed COVID and a really bad dose. Glad he was triple vaxxed as I fear he would have been much worse. It's really hit us in the last few weeks Kali our other electronic engineer is also very ill with COVID and losing weight (from nearly nothing) and two of our production people have just recovered for the second time.

Now the worse news is that the DSP we are using in the pre amp the ADAU1467WBCPZ300 has had a minor price increase from around $10 to anywhere between $170 to $350 each!! Something to do with COVID shutting down Chinese factories and panic buying by the automotive sector primarily soaking up the world stock until some time next year.

So this may cause a price increase on the preamp, also we are under pressure from companies wanting to distribute the product to increase the price significantly. My tip is get in early if you can.

Just sayin

Best of thoughts for those struggling with COVID Chucky. Sorry to hear about the potential price increase, but in one case, sounds like distributors feel like it is not priced correctly for the value, compared to available options in the market. That could be a good thing for Involve....maybe not so good for us QQ insiders!

I assume that means if interested, buy during a pre-order, early sale, etc. that Involve may offer on an early run?

Same thing is happening with the FPGAs I want to use in my new design, 52 weeks lead-time, and the smaller one is quoted as April 2024! As for the price....😱 So the project will have to be delayed.

Same for the first back and about 1 cm higher on second batch as we are moving eventually to a slightly higher standard

Soo.. being special special, what are the dimensions in say, Pico leagues?
( I'll settle for MM in a pinch ...)

I'm about to order a walnut side panel enclosure to house my two two-channel amps, and want it to match the total width of the new SM and the pre, when sitting side by side. The two Involve pieces will sit underneath, to allow the amp to breathe and not spit roast the decoder/preamp..
