  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.

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, balanced; 

10 k ohms, unbalanced.

Maximum Input Signal: 

+22 dBu typical.

AC Line Voltage and Frequency Configurations 
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 
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-fre-

quency content of the input signal and “synthe-
sizes” a new signal that is the same as the input 
signal but one octave lower. The new synthe-
sized signal is then mixed with the original signal 
to create the effect.

Output Limiter:

 Prevents clipping.

Presets:

 20 presets, 19 of which are user-

defi nable.

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 channel, illu-

minates when a very low-level signal is present at 
input. May be used for troubleshooting 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 channel, 

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, illumi-

nates under excessive temperature conditions. 

Power Indicator: 

Blue LED illuminates when the 

amplifier has been turned on and has power. 

Back Panel Controls and Connectors 

AC Line Connector: 

NEMA 5-15P (15A).

Input Connector: 

XLR, one per channel.

Link/Out Connector:

 Loop-thru signal from input 

connector for linking to another amplifier, one per 
channel.

Output Connectors:

 Two Neutrik

®

 Speakon

®

NL4MP (mates with NL4FC) output connectors. 
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; overloaded power 
supplies; excessive temperature; chain destruction 
phenomena; excessive output current, input over-
load 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. (48.3-cm) 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.

Regulatory Certifications

Other Applications

Note: Specifications apply to units in Stereo mode with 
8-ohm loads and rated input sensitivity unless other-
wise specified.

T

he XTi Series of Crown

®

 amplifiers are professional tools designed and built for portable PA appli-

cations. 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 
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.
