Change the setting only as needed.

Check the switch setting to be sure it is appropriate for the local power standard.

WARNING: Be sure to disconnect the mixer/amplifier chassis from AC power before changing the input voltage setting on the rear connection panel.

4.8.2 Fuse type

Be sure the proper supplied fuse is inserted in the fuse box. Replace the fuse as needed with the proper type. 120V units require a T6.3AL/250V fuse. 220V-240V units require a T3.15AL/ 250V fuse.

4.8.3 AC POWER connection

Insert the proper power cord for the voltage used in your region.

4.9 DC POWER connection

This unit allows for +24V DC battery backup power in case there is a mains power failure. There will be a noticeable reduction in output due to the limited power of this backup power source.
