Crown Audio XTi 2000, XTi 1000 User Manual
XTi Series
he XTi Series of Crown® amplifi ers are
professional tools designed and built for
portable PA applications. The series
T
includes three models which are identical
except for output power: XTi 1000, 2000 and
4000. All are rugged and lightweight, and offer
unmatched value in their class.
XTi-Series amplifi ers feature an LCD screen
with speaker presets for crossover frequencies, EQ, limiting, delay, and a subharmonic
synthesizer. Other features include a switchmode universal power supply, useful function
indicators, proportional-speed fan-assisted
cooling, XLR inputs, Speakon
ing-post outputs, short-circuit protection and
more.
With their powerful, reliable performance,
XTi-Series amps easily handle 2-ohm loads
and are capable of chest-thumping lows. Plus,
your investment in an XTi-Series amplifi er is
backed by Crown’s Three-Year, No-Fault, Fully
Transferable Warranty.

to 400 Hz.
Crosstalk: > 70 dB below rated power, 20 Hz
to 1 kHz.
Input Stage: Input is electronically balanced
and employs precision 1% resistors.
Input Impedance (nominal): 20 k ohms, bal-
anced;10 k ohms, unbalanced.
Maximum Input Signal: +22 dBu typical.
AC Line Voltage and Frequency Confi gura-
tions Available: 100V, 120V, 220-240V
50/60 Hz.

DSP Section
Input EQ: 6 parametric fi lters per channel with
adjustable Q, ±15 dB boost/cut. Also adjustable
high and low shelving fi lters. This 8-fi lter EQ
section can be bypassed.
Crossover Filters: Highpass and lowpass per
channel. Butterworth 6/12/18/24 dB per octave. Linkwitz-Riley 24/48 dB per octave. Also
includes ±15 dB bandpass gain and polarity
control.
Delay: For signal alignment of driver; 50 mS
total delay.
Subharmonic Synthesizer: Takes the lowfrequency content of the input signal and
“synthesizes” a new signal that is the same
as the input signal but one octave lower. The
new synthesized signal is then mixed with the
original signal to create the effect.
Output Limiter: Prevents clipping.
Presets: 20 presets, 19 of which are user-de-
fi nable.

Crown’s Three-Year, No-Fault, Fully Transferable Warranty
Crown offers a Three-Year, No-Fault, Fully Transferable Warranty for every new Crown amplifi er—an unsurpassed industry standard. With this unprecedented No-Fault protection, your new
Crown amplifi er is warranted to meet or exceed original specifi cations for the fi rst three years of
ownership. During this time, if your amplifi er fails, or does not perform to original specifi cations,
it will be repaired or replaced at our expense. About the only things not covered by this warranty
are those losses normally covered by insurance and those caused by intentional abuse. And the
coverage is transferable, should you sell your amplifi er.
See your authorized Crown dealer for full warranty disclosure and details. For customers outside
of the USA, please contact your authorized Crown distributor for warranty information or call
