The 

K Series amplifier can be configured to operate at

any line voltage in the world. It is also made to operate
at 50- or 60-hertz frequency with no modification. To
convert from one line voltage to another, change the
Voltage Plug (P7), a 9 pin connector plug on the Con-
trol PWA. Refer to Figure 4.1 for the Crown Part Num-
ber of the plug you need. These plugs are available
from the Crown Parts Department.

The Voltage Plugs have jumpers installed which con-
figure the primary power transformer windings for the

appropriate operating voltage. Figure 4.1 has informa-
tion on jumper location for each voltage.

When wiring the molex connector the proper insertion
and removal too should be used (example, Amp
#458994-2).

When converting from the 100V range to the 200V range,
or vice versa, be sure and change the back panel line
fuse. The fuse values and Crown Part Numbers are
listed in Figure 4.1.

For your reference, Figure 4.2 shows the Control PWA,
P7, and the pin configuration of P7. To access the Con-
trol PWA, remove the bottom cover of the amplifier.
The Control PWA is located in the center of the chas-
sis. For additional information on disassembly and as-
sembly of the amplifier refer to Chapter 5.
