There's not a whole lot to the MidiMan MiniMixer - eight inputs, two outputs, no EQ, and no effects. So why buy a MiniMixer? Well, for one, it will fit in your back pocket. It makes a great little mixer for small gigs. It's great for submixing effects sends. It's great for submixing effects returns. I think every musician ought to keep one or two handy in their audio toolbox. The MiniMixer features ten 1/4" unbalanced jacks on the rear panel. Four jacks are labeled group A and four group B, with single mono outputs for each group. What makes the MiniMixer so handy is that each group has three levels of gain, and the inputs can be summed to mono instead of a stereo/dual-mono configuration. This opens up the possibility for synths on one group with low gain, and microphones and guitars on the other group with high gain. The unit is powered by a single nine volt battery, and the enclosure made of nice heavy gauge steel. Mine has been in constant use/abuse for over six years with nary a scratch. A definite best buy for under $80.
