Some polymer caps ..

Had some interested in a 1U version. Seems like it would be easy enough to mount the sidechain boards and just wire pots in? Could use those dact type stepped pots even and only have a single set of knobs for stereo since those are dual gang?

Stepped switches would be a lot to wire...

Talking about the first revision boards..Not sure how big the new ones are??

[Heikki]

This version has the everything on one board. There's no separate sidechain boards. Pots or rotary switches are wired from the board.

[scott2000]

I didn't realize that. The new diode version doesn't use the sidechain boards?
It wasn't clear in the build pic but it wasn't really a build I guess....

[Heikki]

In the picture the grey wires coming from underneath the board are wires to the potentiometers.

Very cool design! What are the dimensions of the board? Also, how much current does it draw?

[Heikki]

Current draw at idle is maybe 60mA. Current draw will be more if the output is driving 600 ohm loads, but those are rare these days. I used a 18V/1A wall wart for power.

I'll check the dimensions when I get home.

[Heikki]

Dimensions are 270mm x 200 mm.
