Many small groups wish to practice using their home stereo system - the MX56s provides a way to mix a vocalist, a cd or cassette player, and a couple of instruments together, and send the signal to a stereo system power amp or a regular sound reinforcement amplifier.

The MX56s has two 1/4 inch unbalanced inputs, one XLR balanced Mic input, and a stereo RCA (mixed to mono) input. Outputs are dual RCA and individual 1/4 inch instrument and line-level outputs. The MX56s has a power led and power switch, and comes with a battery. The AC adapter is optional.
