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): XTi 1K, 2K, 4K: 100 dB (A
weighted). XTi 6K: 103 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 Configura-
tions Available: 100V, 120V, 220-240V
50/60 Hz.
AC Line Current (120VAC amplifier playing
1/8 power pink noise into 4 ohms per ch):
XTi 1000: 6.8A, XTi 2000: 8.3A, XTi 4000:
10.5A; at idle draws no more than 38 watts.
XTi 6000: 15.3A; at idle draws no more than
180 watts.
Operating Temperature: 0° C to 40° C at
95% relative humidity (non-condensing).
DSP Section
Input EQ: 6 parametric filters per channel with
adjustable Q, ±15 dB boost/cut. Also adjust-
able 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
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 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-
definable.
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.
Signal Indicator: Green LED, one per chan-
nel, illuminates when a very low-level signal
is present at input. May be used for trouble-
shooting cable runs.
–10 Indicator: Green LED flashes when
output 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
conditions.
Power Indicator: Blue LED illuminates when
the amplifier has been turned on and has
power.
Rear Panel Controls and Connectors
AC Line Connector:
XTi 1K, 2K, 4K: NEMA 5-15P (15A).
XTi 6K: NEMA 6-20P (20A)
IEC C20 (20A)
Input Connector: XLR, one per channel.
Link/Out Connector: Loop-thru signal from
input connector for linking to another ampli-
fier, one per channel.
Output Connectors: Two Neutrik
®
Speakon
®
NL4MP (mates with NL4FC) output connec-
tors. Channel-1 Speakon
®
is wired with Ch. 1
and Ch. 2 outputs for use with optional single
4-conductor cable. Two binding post outputs
(in parallel with Speakon
®
connectors).
HiQnet USB Connector: Type B, connects to a
HiQnet network.
Protection
XTi-Series amplifiers are protected against
shorted, open or mismatched loads; over-
loaded power supplies; excessive tempera-
ture; chain destruction phenomena; excessive
output current, input overload damage; and
high-frequency blowups. They also protect
loudspeakers from input/output DC, large or
dangerous DC offsets and turn-on/turn-off
transients.
Construction
Chassis: Steel.
Cooling: Proportional speed fan with front-to-
rear airflow.
Dimensions: EIA Standard 19-in. rack mount
width (EIA RS-310-B), 3.5 in. (8.9 cm)
high and 12.25 in. (31.11 cm) deep behind
mounting surface. XTi 6000 is 16.2 in. (41.15
cm) deep.
Net Weight:
XTi 1K, 2K, 4K: 18.5 lb (8.4 kg).

Other Applications
T
he XTi Series of Crown
®
amplifiers are professional tools designed and built for portable PA applica-
tions. 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 frequencies, 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 binding-post
outputs, short-circuit protection and more.
