"One or multiple miniDSP boards can be connected
to a single potentiometer for master volume control of multiple channels." (User Manual, p.11)

I've got it as one board could drive the volume of the multiple boards...

That's it.
Please diagram it, it's not so hard I think. In manual diagram not so clear, I want to see example with two, like: left channel and right and connection of potentiometer. Also maybe better to use stereo potentiometer...

Magic ? Potentiometer must be wired to both as minidsp says.

Mmmmh, there must be some "lost in translation" here to ask us for a diagram for such a simple statement.. Anyway, see updated user manual. I'm afraid that I don't see how we can make this clearer....

In the end, your statements are quite confusing since it seems like you're looking for a Left & Right volume control (one pot for one board, another pot for the other kit). So maybe you don't even need this diagram....

- If you want 2 levels control, you need 2 independent pots connected.
- If you want one level control (master volume) for 2 boards, you need one pot.

It's digital volume control on the DSP, so the analog thinking you're using doesn't apply.

Hope this makes sense.

Perhaps. Just give more examples of connection.
As per your new comments in manual I must connect pot. in such way as in attachments.

Yes, master volume.

By digital volume control, I imply that it's simply a signal between 0 to 3.3V (depending on Pot position) being sampled by the ADC on the board and affecting digitally the Digital Signal Processor.

It's not like analog audio where you'd actually be attenuating the analog signal directly....

Anyway, without confusing you too much with new concepts: a single analog pot for 2 boards (master volume control) is all you need.

Hope this makes more sense now.

Ic, thank you for answer. So analog volume control for my system will be very complicated ) control 8 channels at a time.

p.s.: my system in progress: ImageShack Album - 26 images
I'm too busy to complete it so far, but later maybe u can find some review on your forum.
