dard 15 amp IEC receptacle at the rear of the amplifier chassis. Two
XA200’s may be run on a single 15-amp circuit. This amplifier is
equipped for operation with an earth ground provided by the users
AC outlet. Never defeat this ground connection. The signal ground
of this amplifier is connected to earth through a power thermistor,
which provides a safety ground but provides protection from irritating
ground loops.
As a safety issue we suggest that the power cord should be the last
cable installed on your power-amplifier. You may, if you wish, substi-
tute a 15-amp aftermarket power cord for the one we have supplied.
Only use power cords, which meet all local safety standards and carry
acceptance marks from the local regulatory authority. The power cord
should be attached to the amplifier prior to plugging into house power.
Place the rear mounted switch in the off (down) position before plug-
ging in this amplifier.
The amplifier’s voltage and current rating are indicated on the rear
panel. It will be either 240 volts, 220 volts, 120 volts or 100 volts, all
with a restorable type circuit breaker of the appropriate ampacity. The
inclusion of this re-settable circuit breaker does away with the need for
disposable fuses. The frequency rating of the AC line source is 50 to
60 Hz in all cases. Please verify that the amplifiers indicated voltage
requirements are consistent with the supplied voltage and current at
your location. Transformers are input voltage specific and their change
is not a trivial matter.
Looking at the rear panel you will see the AC power cord receptacle,
a power switch / breaker, two pairs of output connectors which allow
for speaker bi-wiring, a single pair of 5 way connectors for remote
turn-on, a single RCA input connector and a single XLR balanced input
connector.
Make sure that the rear panel power switch/breaker is off (down).
Plug the AC cord into the back of the amplifier, and then into the wall.
Then turn the power switch/breaker on (up). The lights in your house
will blink when the power supply charges the capacitors. (Note: The
power switch/breaker is never to be used as a “safety device” or “emer-
gency disconnect” for this product. This device provides current limit-
ing which will protect the amplifier, it will not provide personal shock
protection in the event of a reversed hot / neutral, lack of grounding
or other improper wiring in the supplied mains voltage.)
On the front panel, the “Standby” LED indicator should be glowing
blue, indicating that AC power is available and the capacitor banks are
