Passive mixer with powered preamp?

VanZea · 3rd May 2010, 07:08 PM

I'm a musician (keys) and I'm trying to streamline my setup. On stage I use three stereo devices (2xsynth, 1x sampler). All those devices have a volume knop, so on my current mixer (a very small Behringer) I don't use the channel-volume knobs.

I once made a passive mixer consisting of a few resistors which works great, but weakens the signal going to the PA and my monitor.

Can anybody point my to a diy preamp kit (with only a volume control) I can use with my passive mixer? Battery powered (9V) would be great. Could I use 2 of those parallel (on for my monitor, and on for the PA) on the same signal? I need to be able to adjust the signal going to my monitor independent of the signal going to the PA.

Any other suggestions to minimalize my setup?

Thanks,

This is exactly what I was looking for. Are there any kits available somewhere for the amp-part of the device?

I now see I can also order the board at the provided link. Thanks again, all my questions are answered.

Keep in mind that setting one control does affect the other inputs. It is much better to use a buffer on each control.
