At the bottom right side of the mixer is a microphone input with preamplifier and gain pot. The microphone input jack takes a 1/4” TRS phone plug. Above it is the gain switch and knob which set the gain of the preamp. The switch has two different ranges, 55db and 70db to cover most microphones that needs to be boosted to eurorack signal levels. The microphone input can also be used for a signal from some other source such as an electric guitar or line level electric piano.

On the top right of the mixer, is one "left” channel output jack, and one "right” channel output jack, two mono MONITOR outputs, and one stereo EXPANSION IN jacks. These last two jacks are actually a pair of inputs without attenuators, assign control, or access to the MONITOR output. The jack on the left goes directly to the "left" output and the left right goes to the "right" output. These inputs can be used to link the two mixers to form one 12 in, 2 out" mixer. To do this simply patch the SIGNAL outputs of one mixer into the EXPANSION IN inputs of the other.
