Crown XTi 1000 User manual

XTi Series
XTi SERIES
The XTi Series of Crown®amplifiers are
professional tools designed and built for
portable PA applications. The series
includes four models which are similar except
for output power: XTi 1000, 2000, 4000 and
6000. All are rugged and lightweight, and offer
unmatched value in their class.
XTi-Series amplifiers 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 amplifier is
backed by Crown’s Three-Year, No-Fault, Fully
Transferable Warranty.

Crown’s Three-Year, No-Fault, Fully Transferable Warranty
Crown offers a Three-Year, No-Fault, Fully Transferable Warranty for every new Crown ampli-
fier—an unsurpassed industry standard. With this unprecedented No-Fault protection, your new
Crown amplifier is warranted to meet or exceed original specifications for the first three years of
ownership. During this time, if your amplifier fails, or does not perform to original specifications,
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 amplifier.
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
574-294-8200.
XTi Series
DSP Section
Input EQ: 6 parametric filters per channel with
adjustable Q, ±15 dB boost/cut. Also adjustable
high and low shelving filters. This 8-filter 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-
finable.
Front Panel Controls and Indicators
Level: Detented rotary level control, one per
channel.
Power Switch: On/off switch applies AC power
to the amplifier.
Sel/Prev/Next Buttons: Three buttons near the
LCD screen are used to access menu items and
front panel lockout.
LCD Screen: Backlit liquid crystal display
shows speaker presets.

ent at input. May be used for troubleshooting
cable runs.

signal exceeds –10 dB below clip.
–20 Indicator: Green LED flashes when output
signal level exceeds –20 dB below clip.
Ready Indicator: Green LED, one per chan-
nel, illuminates when the amplifier is ready to
produce audio.
Clip Indicator: Red LED, one per channel, turns
on at the threshold of audible distortion.
Temp Indicator: Red LED, one per channel,
illuminates under excessive temperature condi-
tions.

Protection
XTi-Series amplifiers are protected against
shorted, open or mismatched loads; overloaded
power supplies; excessive temperature; chain
destruction phenomena; excessive output
current, input overload damage; and high-fre-
quency blowups. They also protect loudspeak-
ers from input/output DC, large or dangerous
DC offsets and turn-on/turn-off transients.
