Mixer This is a simple 3 channel mixer with individual volume control and one output. Runs on a 9 volt battery or 9volt dc power. Uses TL074 ic and has an onboard trimpot for fine adjustment.

I designed this with the goal of creating a very simple and inexpensive mixer, purely for utility. There is no artwork on this board. Another version wit artwork will be coming soon.

Works great for combining simple audio devices. (I use it with some analog synth gear to feed everything into an audio interface on my laptop).

If audio source going in is too high, some clipping may occur. To prevent this, run lines into the mixer at low volume and connect an amplifier in line with the mixers output.

This listing only comes with the board. All other components will have to be sourced by buyer. All components will need to be soldered onto the board.

Board comes 53mmx43mm. Resistors, TL074 chip, potentiometers and 1/8” audio jack NOT INCLUDED.
