Installation and Connections

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. When all seven of the power modules
volts. It should be sufficient to allow the other devices such as preamplifiers and A/V source units
to share a wall socket, but power amplifiers such as the LPA-1 and a video display (big screen TV
or video projector) should be provided a SEPARATE electrical connection on a SEPARATE circuit.
As the LPA-1 has a minimum requirement that can consume nearly one entire circuit, please use a
second (separate) electrical connection for other devices. DO NOT plug the LPA-1 into a power strip
or extension cord unless the device is specifically designed and rated for high current use.
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 LPA-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 and cycles
through each channel until complete, then all channels illuminate 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 LPA-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 LPA-1. The LPA-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 LPA-1.
Before placing the LPA-1 on a shelf, verify that the weight bearing capacity of the shelf is 75 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.
