Crown xti amplifiers

Author: Robert Hook

Introduction

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 frequencies, EQ, limiting, delay, and a

sub harmonic 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.

Features

Integrated speaker presets with LCD front panel display

  • Accurate, uncolored sound with very low distortion for the best in music and voice reproduction
  • Advanced protection circuitry guards against: shorted outputs, open circuits, DC, mismatched

loads, general overheating, high-frequency 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 lb (24 lb for XTi 6000); weight sets a new

standard in lightweight amps.

  • Speakon and binding post outputs, XLR inputs and loop-thrust
  • Comprehensive LED status per channel

Specifications

Output Power: See power charts below of crown power amplifier.

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): 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, 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 (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%

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-frequency blowups. They also protect loudspeakers

from input/output DC, large or dangerous DC offsets and turn-on/turn-off transients.

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 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.
