help with a lost schematic

[pucho812]

I seem to have misplaced a summing schematic from  our old friend NYDave...

This one had panning, volume control and was passive.  any one still have it?

This it?

 

[pucho812]

sadly no. this one had actual pan pots....

But thanks for trying. IIRC this used a single deck 10K linear pot for panning.

The typical single pot (-3dB) pan pot configuration has about -10dB insertion loss  so figure Nx +10dB for makeup gain.

Not crazy with modern low noise op amps (or any crazier than passive mixing already is).

Chicken Dinner!

That's interesting, I haven't seen this one before - just NYD's earlier schematic with level, mute and LCR panning.

Does anyone know the thread this is from? I'd love to read if anyone's tested it.
