Crown Audio XTi 1000 - Manual

XTi Series
X T i S E R I E S
T he XTi Series of Crown ® amplifi ers are
professional tools designed and built for
portable PA applications. The series
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 frequen-
cies, EQ, limiting, delay, and a subharmonic
synthesizer. Other features include a switch-
mode universal power supply, useful function
indicators, proportional-speed fan-assisted
cooling, XLR inputs, Speakon
® and bind-
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.

Specifi cations
Output Power: See power charts below.
Voltage Gain at 1kHz, 8 ohm rated output:
XTi 1000: 30.5 dB
XTi 2000: 32.9 dB
XTi 4000: 34.2 dB
Frequency Response: +0/–1 dB from 20 Hz to
20 kHz at 1 watt into 4 ohms.
Load Impedance: Safe with all types of loads.
Rated for 2 to 8 ohms in Stereo mode, 4 to 16
ohms in Bridge-Mono mode. The XTi 1000 A1
(100V version) is rated for 4 to 8 ohms Stereo,
8 to 16 ohms Bridge Mono.
Sensitivity: 1.4V
Signal to Noise Ratio (below rated 1 kHz
power at 8 ohms): 100 dB (A weighted).
Damping Factor: Better than 500 from 20 Hz
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.
AC Line Current:
XTi 1000: 6.5A
XTi 2000: 6.9A
XTi 4000: 8.0A
At Idle: Draws no more than 90 watts.
Operating Temperature: 0° C to 40° C at 95%
relative humidity (non-condensing).
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 oc-
tave. 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 low-
frequency 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.
Features
