Installation and Connections
AC Power Considerations
The majority of household electrical sockets (in places other than the kitchen and garage) are 15 amperes maximum, which is
sufficient to power your Ultra series amplifier. However, remember to account for the electrical power that other
components will require if they share a common wall socket or electrical circuit. Most DVD players, preamplifiers and A/V
source units are fairly low current items, and can successfully share a wall socket with your power amplifier, but big screen
TVs and video projectors usually have minimum current requirements that can consume nearly an entire circuit. Refer to the
owner’s manuals of your audio/video devices to assess your electrical power requirements for your home entertainment
system. If you have any questions relating to issues with the power requirements for your X amplifier, please contact
Emotiva Support at: 877‐366‐8324 (877‐EMO‐Tech)
Surge Protection ‐ Along with built‐in noise filtering, your Ultra Series amplifier is equipped with overcurrent, undercurrent,
and spike protection.
Upon powering up your X amplifier 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 /Heat Considerations
Ultra amplifiers employ convection cooling, which is very effective and completely noiseless. Under normal operating
conditions, your Ultra amplifier will remain cool to mildly warm, but considerations for heat should be taken into account
during placement.
Place your amplifier on a flat, level surface, with the weight distributed equally on all four feet. If using a cabinet or shelf,
please make sure that there is sufficient ventilation and there is at least 6 inches of free air space above the amplifier and 3
inches on each side. If adequate ventilation is not available, your may consider installing two small brushless DC fans (such as
those used in computer cases) to provide continuous airflow around the unit. If the amplifier is located on a carpeted
surface, place a board under the amplifier’s feet.
NOTE: Expansion and contraction of the amplifier’s heat sinks may cause a faint ‘clicking’ sound at times. This is relative to
how warm the heat sinks become and how quickly they cool. This is completely normal, and no cause for concern.
Do NOT block the ventilation holes on the amplifier.
Your Ultra amplifier 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 amplifier.
Before placing the amplifier 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.
