This listing is for 2 Emotiva XPR-1 solid state mono power amplifiers in excellent used
These rarely show up, not often seen on ebay or audiogon.
Listed as two amps per item, the buy it now of $4000 is for two amps.
Offered for $4000 including domestic freight shipping. At 100 lbs each it's risky not to! Not fedex as shown, no choice for freight.
This series of reference quality amplifiers, the
Emotiva XPR-1, while hardly inexpensive in an absolute sense, comes in at a
price just north of a four-figures.
This is substantially less than most other amplifiers that boast similar
specifications, which often approach, and some cross, the five-figure mark.
Clocking in at 99 pounds per channel, and it is only a
single channel, the XPR-1 is a monster of an amplifier. The XPR-1
sports the same 30 pound, 2.5 kVA
transformer, 240,000 uF capacitor bank, and thirty six 250 watt output
transistors as the XPR-2, just with one less input channel
and providing nearly twice the power output per channel. The two halves
of the XPR-1 feature mirrored differential gain stages that
eliminate op-amps from the signal path when running from balanced inputs.
One the inside, the XPR-1 is a balanced, differential class
A/B amplifier with a triple Darlington output stage and a class H modification
to the power supply topology, which is said to increase power efficiency. The power supply capacitor bank is comprised
of a large number of smaller devices utilizing 24 x 10,000 uF capacitors. The advantage of using a larger number of
smaller capacitors is said to be in improved transient response with shorter
charge/discharge cycle times.
Emotiva states that high quality electronic components are used
throughout the internal circuitry of the XPR-1 including precision metal film
resistors, low ESR film capacitors, and multi-layer glass epoxy printed circuit
The internal circuitry is controlled with an ARM-7
microprocessor that monitors the XPR-1 to ensure operational stability and
provide protection against common electrical fault and thermal issues such as
over-temperature, shorted speaker connections, and ground fault problems. The status of the protection and other
circuitry is reported by dimmable front mounted LEDs that can be oriented to
read left/right/vertical with level metering for VU and peak current with hold
and release functionality.
To fuel this engine of audio, Emotiva recommends a dedicated
20 amp circuit for the XPR-1, and because you will need at least two
what that really means is two dedicated circuits to actually hit the
rated 1kwatt power into an 8 ohm load, which is a draw of 1500 watts for
Of course you can still run both amps off one dedicated 20A line and
probably never come close to drawing full power with both channels
driven for real program material. The XPR-1 supports 115/230 VAC at
50-60 Hz operation and auto switches
between the two voltages. So, power mongers will want to install a
dedicated 220V line to really unleash the big dog.
Inside the chassis, there are three large aluminum heat
sinks arranged in an H pattern forming compartments that separate the output
transistors, the transformer, and the capacitor bank. The two primary legs of the heat sink H run the full length of
the chassis and appear to function as an internal reinforcing frame with
attachments to the front and rear plates.
The faceplate of the XPR-1 is formed from multiple 1 inch
machined billet aluminum sections that are laser embossed and hand
polished. In addition to the LED meter
display, the faceplate includes vertical accent lights and several buttons to
operate the meter display for setting peak, dim, meter, and orientation along
with a soft touch stand-by button with in-rush current limiting circuitry and
an operation indicator LED.
At the rear, the XPR-1 features user select-able balanced XLR
and unbalanced RCA inputs that are set with a toggle switch. The unbalanced RCA input is constructed of
machined, gold plated solid brass. The
custom manufactured Emotiva speaker terminals are heavy duty gold plated
binding posts with clear acrylic insulators that can accept heavy gauge bare
wires, spade lugs, or banana plugs and Emotiva recommends using at least 10
gauge speaker wire or lower to minimize resistive heat losses. The XPR-1 also
includes a 12V trigger input and output, IEC detachable power cord terminal, a
rocker power switch, and an input voltage indicator LED showing the 115/230V
So why does anyone need all of this power? It is not really about producing high
volume, it's about effortless control and dynamics. It is about the ability of an amplifier to have the strength to
pry every last detail free from a recording and hold it out on display for all to
