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 channel output jack, and one channel output jack, two mono "left” "right” 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.
Horizontally on the bottom are the six mixer signal input jacks ('A" through "F").
Above these are s. Putting any of these switches in the up position sends the signal from that input six yellow MONITOR switche

channels on either side of each mixer ("A" and "F") feature voltage controlled assign. Without any control voltage channel "A" is
assigned to the left output and channel "F" goes to the right output. As a control voltage increases the signal pans to the other
output channel. The two LED's below each control voltage input indicate which channel the signal is going to.
