AC Power Considerations
Ensure that the unit is plugged into an outlet capable of supplying the correct voltage and current
specified for your model. Remember to account for the electrical power that other components will
require if they share a common wall socket or electrical circuit. The majority of household electrical
sockets in places other than the kitchen and garage are 15 amperes maximum. Most DVD players
and other source components are fairly low current items.

Refer to your preamplifier, A/V source component(s), and video display owner’s manuals to learn
the power requirements so you can safely plan your electrical power requirements for your home
entertainment system.
Upon powering up the XPA-1 with the front panel switch or via 3.5mm trigger input (switch on the
rear panel must be set to “ON”), you will notice the front panel LED lighting starts off red for 5 seconds
and then turns to blue.
This indicates the amplifier is
“on”, functioning normally , and ready for
operation. If you experience no LED light or a blinking red LED light while the amplifier is on during
(otherwise) normal operation, please refer to the troubleshooting section of this manual.
Physical Placement
Place the XPA-1 on a flat, level surface. Please distribute the weight equally on the four feet. Please
give this unit adequate ventilation for proper cooling when placing. If this unit is placed in a cabinet,
please make sure that the cabinet’s rear is open to fresh air and there are at least 6 inches of free air
space above the amplifier and 1 inch on each side. If the amplifier is located on a carpeted surface,
place a board under the amplifier’s feet. If the cabinet’s design will not accommodate an open rear,
install two small brushless DC fans (such as those used in computer cases) to provide continuous air
flow into and out of the cabinet.
Do NOT block the ventilation holes on the XPA-1. The XPA-1 is equipped with a massive torroidal
power transformer. This transformer generates a magnetic field that could induce a hum in a turntable
(particularly a turntable equipped with a moving coil cartridge). Do NOT place a turntable directly
above or directly adjacent to the XPA-1.
Before placing the XPA-1 on a shelf,verify that the weight bearing capacity of the shelf is 80 lbs
or greater. The amplifier is heavy and should be placed toward the bottom of an audio rack to
minimize the rack being unnecessarily top heavy.
