Connecting the AC Supply
The power cord connects to a standard 20 amp
3-pin IEC-type male connector on the back panel
(see
Figure 2.6
).
Make sure the Breaker/Switch on
the front panel is switched to the OFF (O) position.
Make sure the power cord is inserted and seated
fully into the IEC connector by moving it slightly
back and forth and up and down while pushing
in. The power cord is relatively stiff and should be
routed so that there is no excessive force pulling to
the sides or up or down that would stress the pins
or internal connections. Tighten the cord strain
relief screw to lock the power cord in place.
Review the factory-set supply voltage and ampli-
fier configuration detailed on the label placed on
the side of the amplifier (see
Figure 2.7
). This
configuration can be changed by the user. See the
Advanced Configuration
section for more infor-
mation.
