Important Safety Precautions and Explanation of Symbols
!
!
The exclamation point within an equilateral triangle is intended to alert the user to the presence of
important installation, operation, and service instructions in this manual.
The lightning ash with arrowhead symbol within an equilateral triangle is intended to alert the user
to the presence of uninsulated dangerous voltages within the enclosure that may be of sufcient
magnitude to constitute a risk of electric shock to the user.
Please read this manual thoroughly before attempting to install, congure, or operate the XPR-2.
After successful installation and conguration of the XPR-2, be sure to retain this manual in a safe
place for future reference.
Safety is a key component to a long lasting and trouble free installation. Please read and follow
all instructions and heed all warnings on the XPR-2 and in this manual. The vast majority of the
subsequent safety precautions are common sense. If you are not comfortable with the installation
of audio/video entertainment equipment, you should seek the services of a qualied installation
professional or call us for help.
WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT USE THE
XPR-2 NEAR WATER OR IN WET LOCATIONS, DO NOT EXPOSE IT TO RAIN OR MOISTURE,
DO NOT EXPOSE IT TO DRIPPING OR SPLASHING FROM OTHER SOURCES, AND ENSURE
THAT NO OBJECTS FILLED WITH LIQUIDS (SUCH AS VASES) ARE PLACED ON IT. DOING SO
MAY RESULT IN DAMAGE TO THE UNIT AND THE RISK OF ELECTRIC SHOCK, WHICH MAY
RESULT IN BODILY INJURY OR DEATH.
WARNING: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE THE COVER
FROM THE XPR-2. THERE ARE NO USER-SERVICEABLE PARTS INSIDE THE UNIT. REFER
ALL SERVICE TO QUALIFIED SERVICE PERSONNEL.
WARNING: DANGEROUS VOLTAGES MAY BE PRESENT AT THE SPEAKER OUTPUT
TERMINALS OF THE XPR-2 (AND ALL HIGH-POWERED AMPLIFIERS). TO REDUCE THE RISK
OF ELECTRIC SHOCK, DO NOT TOUCH UNINSULATED AREAS OF TERMINALS OR SPEAKER
WIRES UNLESS THE AMPLIFIER IS TURNED OFF. DO NOT SHORT THE SPEAKER OUTPUTS
OF THE XPR-2 TO EACH OTHER, OR TO OTHER EQUIPMENT, WHILE THE AMPLIFIER IS
POWERED ON; SERIOUS EQUIPMENT DAMAGE OR INJURY MAY RESULT IF YOU DO.
To reduce the risk of electrical damage, verify that no short circuits are present between terminals
and / or speaker wires before applying power.
Do not install the XPR-2 near or above any heat sources such as radiators, heating vents, or other
apparatus that produces heat. Do not block any ventilation openings or heat sinks. Avoid installing
the unit directly above other heat-producing equipment unless sufcient ventilation or forced-air
cooling is provided.
Do not install the XPR-2 in locations without proper ventilation. The XPR-2 should not be operated
on a bed, sofa, rug, or similar surface that may block vents. The unit should not be installed in an
enclosed location such as a bookcase, cabinet, or closed equipment rack unless sufcient forced-air
ventilation is provided.
Always install your XPR-2 according to the manufacturer’s instructions and only use attachments or
accessories specied by the manufacturer.
Do not install the XPR-2 on any stand, shelf, or other piece of furniture that is unable to support its
weight. If a cart is used to move the unit, use caution to avoid injury from tip-over.
Connect the XPR-2 only to power sources of the correct voltage (as shown in this manual and on
the XPR-2).
Protect power supply cables from being pinched, walked on, or otherwise damaged. Be especially careful
where the power cable enters the power outlet and the unit.
Only connect the XPR-2 to an electrical outlet or extension cord of appropriate type and rating. MOST
power strips and extension cords are NOT sufcient to safely supply the power required by the XPR-2.
Using a power source of insufcient capacity will constitute a safety risk and also seriously compromise the
performance of the XPR-2
DO NOT defeat the safety purpose of a grounding or polarized plug by removing ground pins or using
unsafe adapters. A polarized plug has two blades - one wider than the other. A grounding plug has a third
ground prong in addition to the two main conductors. The wide blade or third groundling prong is provided
for your safety. If the provided plug does not t your outlet, consult an electrician to replace your obsolete
outlet. If you replace the power cord, only use one of similar type and equal or greater current rating.
The power cable for the XPR-2 should be unplugged from the outlet during severe electrical storms, or
when unused for a long period of time.
Only replace the fuse(s) in the XPR-2 with fuse(s) of proper value and voltage rating.
WARNING: UNDER SOME OPERATING CONDITIONS, THE XPR-2 MAY CAUSE A FUSE OR
CIRCUIT BREAKER IN YOUR BREAKER PANEL TO OPEN, WHICH INDICATES THAT THE XPR-2
IS ATTEMPTING TO DRAW MORE CURRENT THAN YOUR CIRCUIT CAN SAFELY SUPPLY. IF THIS
OCCURS, DO NOT REPLACE THE BREAKER OR FUSE WITH ONE OF HIGHER RATING. DOING
SO MAY RESULT IN THE POSSIBILITY OF FIRE OR ELECTRIC SHOCK, WHICH MAY RESULT IN
SERIOUS INJURY OR DEATH.
The XPR-2 should only be cleaned as directed in the manual. Avoid spraying liquids directly onto the unit
and NEVER spray liquids into the vents. Care should be taken so that small objects do not fall into the
inside of the unit.
You should seek service for your XPR-2 by qualied service personnel if any of the following occur:
1. The power-supply cord or the plug has been damaged.
2. Objects or liquid have fallen or spilled into the vents.
3. The unit has been exposed to rain.
4. The unit exhibits a marked change in performance.
5. The unit has been dropped, or its enclosure or chassis is damaged.
WARNING: THE XPR-2 IS VERY HEAVY. THE XPR-2 SHOULD BE LIFTED BY TWO PERSONS, OR
BY ONE PERSON WITH MECHANICAL ASSISTANCE. THE XPR-2 SHOULD ONLY BE PLACED ON
TABLES, STANDS, OR SHELVES, OR MOUNTED IN RACKS, WITH A CAPACITY OF AT LEAST 200
POUNDS.
NOTE: TO COMPLETELY DISCONNECT THE XPR-2 FROM THE AC POWER MAINS, DISCONNECT
THE AC POWER CORD FROM THE AC RECEPTACLE.
NOTE: THE POWER CORD ON THE XPR-2 MUST REMAIN READILY ACCESSIBLE AT ALL TIMES.

XPR-2
Introduction
The XPR-2 Stereo Reference Power Amplier quite simply delivers all the raw power, superb
sound quality, cutting edge technology, and good looks that you would expect in a agship
stereo amplier from Emotiva.
The XPR-2 can effortlessly deliver 600 watts per channel into 8 ohms and 1000 watts per
channel into 4 ohms with both channels driven, at less than 0.1% THD (that’s 2 kilowatts total
into 4 ohms). At 1 watt, the distortion is a miniscule 0.0025%; and the S/N ratio is an impressive
118 dB below full power. The XPR-2’s two high efciency Optimized Class H™ power amplier
modules are powered by a massive 2.5 kVA toroidal power supply with 240,000 microfarads of
energy storage.
An advanced ARM-7 microprocessor with a custom operating system continuously monitors
operation, runs the high performance LED metering system, and controls the acoustically
transparent high-speed protection circuitry. Gold-plated, machined, heavy duty input and output
connectors ensure that signals are transferred with the utmost delity.
The XPR-2 faceplate, made of 25 millimeters of solid machined aluminum, sports a high-gloss
black nish, and is tooled and polished like ne jewelry. A smoked polycarbonate display window
conceals the LED display when it’s not engaged, and the Emotiva logo laser engraved on the
faceplate proudly proclaims the XPR-2’s place in Emotiva’s superlative new Reference amplier
line. Concealed blue accent lighting completes the picture of cool elegance and effortless
performance.
This philosophy of raw power, quality construction, and precise control is at the heart of every
component in the new Emotiva Reference Series. More important, however, is how the
XPR-2 sounds: simply superb.
The Emotiva XPR-2: classic good looks; limitless power; precise control.
Experience it for yourself.
What are you waiting for?
Happy Listening
