Stereo Mixer 1U - gain?

Hi,

I’m very happy with the Stereo Mixer 1U. It’s simple, nice, small and to the point. And the connectors on the back are very helpfull to expand it.

But i was wondering if it is possible (maybe with a small hack) to boost the gain of one or both of the inputs a bit more. Or to boost the overal output a bit.

Background is the use of some relatively quiet sample module in a small case (so no room for extra gain via another module).

It is possible.

To increase gain of Ch 1:
change R11 and R12 from 100k to something bigger.

To increase gain of Ch 2:
change R13 and R14 from 100k to something bigger.

To increase gain of Output:
Change R23 and R24 from 10k to something bigger.

Thanks @Danjel for the information!
I see its all SMD so maybe not that easy for my soldering skills :wink:
