XTi 6000  
Architectural & Engineering Specifications  
XTi 6000  
power, 20 Hz to 1 kHz. Input Stage: Input shall be electronically balanced  
and shall employ precision 1% resistors. Input Impedance (nominal): 20  
k ohms balanced and 10 k ohms unbalanced. Maximum Input Signal: +22  
dBu typical. AC current draw: 15.3A; at idle draws no more than 180 watts.  
Operating Temperature: 0° C to 40° C at 95% relative humidity (non-con-  
densing).  
The Crown® XTi 6000 power amplifier shall be a solid-state two-channel  
model with a switch-mode universal power supply.  
The outputs shall be usable as stereo or bridged-mono modes of opera-  
tion. The bridged-mono mode shall bridge the outputs to provide increased  
output voltage.  
The amplifier shall include Digital Signal Processing with these functions:  
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.  
The amplifier shall contain controlled slew-rate voltage circuitry to protect  
it against radio frequency interference burnouts. It shall also be protected  
from current overload at its output stage. The slew rate of the amplifier  
shall be greater than 30 volts per microsecond in stereo mode.  
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.  
The amplifier shall temporarily go into a standby mode if its power trans-  
former becomes excessively hot and shall automatically resume normal  
operation once it has cooled to a safe operating temperature.  
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.  
Front-panel controls shall include a power on/off switch, a detented input  
level control for each channel and three buttons for menu navigation of the  
front-panel LCD screen and front panel lockout.  
Output Limiter: Prevents clipping.  
Presets: 20 presets, 19 of which are user-definable.  
The front panel have have the following indicators:  
The amplifier shall be safe when driving any kind of load—even highly  
reactive ones.  
Signal Indicator: Green LED, one per channel, illuminates 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.  
Thermal 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.  
AC line voltage and frequency configurations available shall be 100V, 120V,  
220-240V, 50/60 Hz.  
The amplifier shall have a rugged steel chassis coated with environmentally  
friendly powder. The amplifier shall be fan-cooled.  
The dimensions of the amplifier shall allow for 19 inch (48.3 cm) EIA stan-  
dard (RS-310-B) rack mounting. The amplifier shall be 3.5 inches (8.9 cm)  
tall and 16.2 inches (41.15 cm) deep behind mounting surface.  
The amplifier shall weigh 24.0 pounds (10.9 kg).  
The amplifier shall be designated the Crown XTi 6000.  
The rear panel shall have the following connectors:  
AC Line Connector: NEMA 6-20P (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. Chan-  
nel-1 Speakon® shall be 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.  
The power amplifier shall meet or exceed the following power criteria at 1  
kHz: 2 ohm Stereo (per channel): 3,000W with 1%THD, 4 ohm Stereo (per  
channel): 2,100W with 0.5% THD, 8 ohm Stereo (per channel): 1,200W  
with 0.5% THD, 4 ohm Bridge-Mono: 6,000W with 1% THD, 8 ohm Bridge-  
Mono: 4,200W with 0.5% THD.

The amplifier shall meet or exceed the following performance criteria:  
Voltage Gain at 1kHz, 8 ohm rated output: 37.1 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 2-8 ohms in Stereo mode, 4-16  
ohms in Bridge-Mono mode. Sensitivity: 1.4V. Signal to Noise Ratio (below  
rated 1 kHz power at 8 ohms): 103 dB (A weighted). Damping Factor:  
Better than 500 from 20 Hz to 400 Hz. Crosstalk: > 70 dB below rated
