XTi Series

he XTi Series of Crown® amplifiers are Tprofessional 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 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.

Features

•Integrated speaker presets with LCD front panel display

•Accurate, uncolored sound with very low distortion for the best in music and voice re- production

•Advanced protection circuitry guards against: shorted outputs, open circuits, DC, mis- matched loads, general overheating, high-fre- quency overloads and internal faults

•Extremely versatile, handling a wide range of speaker impedances and outputs

•Switch-mode universal power supply

•Speaker presets for crossover frequencies, EQ, limiting, and delay

•All products fill 2U rack spaces and weigh under 19 pounds; weight sets a new standard in light- weight amps

•Speakon® and binding post outputs, XLR inputs and loop-thrus

•Comprehensive LED status per channel

•Three-Year, No-Fault, Fully Transferable War- ranty completely protects your investment and guarantees its specifications

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.

Specifications

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 Configura- 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 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.
