Simple problem, simple solution

Sometimes you just need a simple solution for a simple problem. For his sample project, a friend wanted a very simple mixer with only panning control over the individual channels. So I designed and built this compact mixer. It has four mono inputs and one stereo output. All the inputs and outputs are ¼” jack sockets. The panpots have a centre detent so you can easily pan a channel to the centre of the stereo field. It is powered by a standard 12 V DC power adaptor.
