Power Supply

The SW AR MX, SW AR MX HV, and SW 6 Component
switchers are equipped with an internal power supply that
operates from any AC line voltage in the 100—240VAC,
50/60Hz range. No configuration is required.

Replacing the fuse

The power supply is protected by a 400 mA, 250V, slow
blow fuse. The fuse is in a holder located below the AC
connector on the rear panel.
To change the fuse, do the following:
1. If the power cord is attached, disconnect it from the
switcher.
2. Insert a small screwdriver blade into the slot provided
at the top of the fuse holder, and pry the holder
open (figure 33).
