IEC MAINS CONNECTOR
7
This is a standard IEC power connector. An AC mains cord having the appropriate AC plug and ratings for
the intended operating voltage is included in the carton.
U.S. DOMESTIC AC MAINS CORD
The mains cord supplied with the unit is a heavy-duty, three-conductor type with a conventional 120
VAC plug with ground pin. It should be connected to an independent circuit capable of continuously
supporting at least 15 amps. This is particularly critical for sustained high-power applications. If the
outlet used does not have a ground pin, a suitable grounding adapter should be used and the third wire
grounded properly.
Never break off the ground pin on any equipment. It is provided for your safety. The use of
extension cords should be avoided but, if necessary, always use a three-wire type with at least a #14 AWG
wire size. The use of lighter wire will severely limit the power capability of this amplifier. Always use a
qualified electrician to install any new electrical equipment. To prevent the risk of shock or fire hazard,
always be sure that the amplifier and all associated equipment is properly grounded.
NOTE: FOR U.K. ONLY
As the colors of the wires in the mains lead of this apparatus may not correspond with the colored
markings identifying the terminals in your plug, proceed as follows: (1) The wire which is colored green
and yellow must be connected to the terminal which is marked by the letter E, or by the Earth symbol, or
colored green or green and yellow. (2) The wire which is colored blue must be connected to the terminal
which is marked with the letter N, or the color black. (3) The wire which is colored brown must be con-
nected to the terminal which is marked with the letter L, or the color red.
To avoid the risk of electrical shock, do not place fingers or any other objects into empty tube sockets
while power is being supplied to unit.
FAN GRILLE
8
A two-speed DC fan supplies cool air to the amplifier. THIS INTAKE SHOULD NEVER BE BLOCKED! The fan
switches to high speed automatically when the unit requires additional cooling. At idle and cool, the fan
runs at low speed. The fan should never stop unless the amplifier is switched OFF or the AC mains power
source is interrupted, or the thermal breaker in the transformer has tripped due to excess heating. The
thermal breaker in the transformer is self-resetting once the excess heat has dissipated.
LINE VOLTAGE SELECTOR SWITCH
9
The CPX series power transformer is designed with two primaries that can be placed in series or parallel
by means of the line voltage selector switch. It is accessible by loosening one screw and rotating the
transparent guard out of the way. Please be sure this is set to the proper voltage for your area before
turn-ing the amplifier on for the first time.
