Yamaha DX21 7.AC Power, 8.Music Rack lnstallation

7.AC Power

8.Music Rack lnstallation

Plug the DX21 AC power cord into an AC wall socket. Be sure that your local line voltage matches that specified on the DX21 rear panel. The POWER switch is located next to the AC cord on the rear panel. NOTE: When setting up your system, be sure to turn the DX21 and any effects units used on BEFORE turning the main amplifier system on. This will prevent the initial power-on shock surge from possible damaging your amplifier and speaker system.

The music rack supplied with the DX21 fits into the two sockets on the rear panel (see diagram).
