REAR PANEL DESCRIPTION
AC Receptacle
This is where you connect the AC linecord to provide AC power to the FUSSION 3000’s
The FUSSION 3000 is shipped with a connector that mates with the AC receptacle on the rear panel. Use heavy gauge wire for the linecord to avoid power losses across the wire. (See page 8 for more info.)
The bar 
A on the rear panel is there to secure the linecord and prevent it from accidentally getting pulled loose from the AC receptacle. Wrap the linecord through the bar and tie it in a knot to secure it.
Note: You can change the AC voltage configuration from 115V to 230V internally by reconfiguring the transformer primary wiring on the power supply board. Contact Mackie Technical Support for instructions
FUSE
Always replace the fuse with the type indicated on the rear panel. Never replace the fuse with one of a higher value than indicated on the rear panel.
WARNING: Make sure you use the correct fuse relative to the AC operating voltage. 115VAC=16A
POWER Switch
Switch up to turn the FUSSION 3000 on, and switch down to turn it off. Make sure the signal source’s level control is down before you turn it on.
POWER/PROTECT Indicator
When the POWER switch is turned on, and the linecord is connected to an active AC Mains supply, this indicator lights green to let you know that you’re ready to rock and roll. If one of the protection circuits in the FUSSION 3000 should trigger, this indicator changes to red. The protection circuits include RMS limiting on the input and thermal protection on the heatsink. If the output begins to clip for more than a few seconds, the POWER/PROTECT indicator changes to red and the RMS limiting protection circuit discretely reduces the input signal until the output is just below clip- ping. If this should happen, turn down the level at the source (mixing console) until the PROTECT light changes back to green.
If the thermal protection circuit should get activated, the POWER/PROTECT indicator changes to red and the amplifiers shut down until the heatsinks cool to a safe operating level. Once the amplifier cools, the thermal protection circuit resets and normal operation resumes. You should determine what is causing the overheating condition and take steps to remedy it (i.e., direct sunlight on the heatsink, not enough clearance for air to circulate freely around the heatsink, etc.).
