I assume you're not talking about buying the console.. :D I have pondered what to do with this technology. I long ago gave up on personally pursuing the kit business since I think the financial model is broken, due to manufacturing automation. There is probably a niche market, or should be, for thes...

Well I've heard back from the PLASA and AES shows and the Peak/VU meter was well received...

I think I have discussed this with you before but not sure if on a forum or in private correspondence. IIRC Paul Buff mentioned something very close in a private conversation about his Transamp a couple decades ago. He was using something like 50-100k resistors for DC bias to bases inside the potted...

That's interesting and mostly good. :geek: While I implemented the real pole for 75usec RIAA time constant in both of my later published preamps (P10 and P100) I suspect the benefit of this is somewhat overstated. Obviously the RIAA record equalization does not rise all the way up to light, so this ...

He probably wrote his own obit...

Tying it to a PCB seems kind of constraining to me. I was hoping it might be seen as a universal meter solution to be integrated into sundry applications. I looked at your GR10 and this PIC approach wouldn't be smaller than that, more like the same size but with two meters in that same or similar fo...

This is mostly a mental exercise on my part. I don't think it would be that attractive as a stand alone line level mixer.

I have done some work with a console company that sells a VCA model so it might be worth them considering for one of their large consoles.

I am pretty sure I could make my digital LM391x in a 18 pin PIC 2x8 or 2x16 of Pk/VU/LIN or any combination (1 PIC and several 8 bit latches). Does anybody have any interest? To get the price right I have to buy 250 min so I don't feel lucky. In onsey twosey this would have to be $10+ which is too m...

I first wrote about current source summing back in 1980. I need to get Wayne that old console design article I wrote, if he doesn't already have it. The principle is pretty simple. Instead of resistors feeding a simple virtual earth inverting amp with the noise gain build up on N+1 for the number of...

I'm not familiar with blammo, but I'm sure my neighbors wouldn't appreciate me using c4 in town.
