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. The Emotiva UPA-7 requires a minimum of 10
amperes @ 115volts or 5 amperes @ 230 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 UPA-7 and a
video display (big screen TV or video projector) should be provided a SEPARATE electrical connection
on a SEPARATE circuit. As the UPA-7 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 UPA-7
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 UPA-7 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 do not see an 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 UPA-7 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 is 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 airflow into and
out of the cabinet.
Do NOT block the ventilation holes on the UPA-7. The UPA-7 is equipped with a massive toroidal 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 UPA-7.
Before placing the UPA-7 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.
