Use ONLY a Yamaha PA-6 AC Power Adaptor (or other adaptor specifically recom-
mended by Yamaha) to power your instrument from the AC mains. The use of other
adaptors may result in irreparable damage to both the adaptor and the MU128.

When connecting the AC power adaptor, first make sure that the MU128 is turned off
(set to STAND BY). Next, connect one end of the power adaptor to the DC IN jack on
the MU128, and connect the other end to an appropriate AC outlet.
5 Power cord hook
Use this to secure the AC power adaptor's cord and connector to the MU128,
to prevent accidental disconnection. Plug the connector into the DC IN jack,
then wrap the cord inside both ends of the hook.
6 OUTPUT L, R jacks (Left, Right)
For connection to a stereo amplifier/speaker system.
7 INPUT L, R jacks (Left, Right)
These are for connection to external sound sources, such as CD players, cas-
sette decks, etc. Neither the front panel VOLUME control nor the built-in
effects and equalizer of the MU128 have any effect on the input sound.
8 XG Plug-in Board expansion bay
This bay accommodates up to three XG Plug-in Boards. To install a board,
first remove the expansion bay cover (page 179). Since the screw is tightened
securely at the factory, you may need to use a screwdriver to loosen it at first.
Normally, it can be fastened and removed simply by using your fingers.
