Using the INPUT Jack

The MU50 also features an INPUT function that allows you to connect an
external audio source (such as an electric guitar, keyboard or CD player)
and mix in those signals with the MU50's Voices — without the need for
an external mixer. For example, this allows you to play a guitar or keyboard
over backing tracks played with the MU50's Voices from a MIDI
sequencer. The INPUT jack is a stereo input, and the left and right chan-

meter bars for indicating the signal levels.
