Crown XTi 4002 Power Amplifier Specifications

Power
- 2Ω Stereo (per ch.): 1600W
- 4Ω Stereo (per ch.): 1200W
- 8Ω Stereo (per ch.): 650W
- 8Ω Bridge-Mono: 3200W
- 4Ω Bridge-Mono: 2400W

Integrated Processing
- 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 octave. Linkwitz-Riley 24/48 dB per Octave. Also includes ± 15 dB bandpass gain and polarity control.
- Output EQ: 8 parametric filters per channel with adjustable Q, ±15 dB boost/cut. This 8-filter EQ section can be bypassed.
- Delay: For signal alignment of driver; 50 mS of total delay.
- SubHarmonic Synth: 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. New: Users now have control over frequency, gain, and filter type.
- Peakx Plus Limiter: User defeatable limiter that allows users to control Threshold, Attack, and Release times.
- Presets: 50 total presets, 49 of which are user-definable.

- LCD Screen: Backlit liquid crystal display that shows preset and processing status

Indicators
- 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).
- -10db Indicator: Green LED flashes when output signal exceeds -10 dB below clip.
- -20db 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, illuminates under excessive temperature conditions
- Power Indicator: Blue LED illuminates when the amplifier has been turned on and has power

Input/Output Connectors
- Input Connectors: XLR, one per channel
- Link/Out Connector: Loop-thru signal from input connector for linking another amplifier, one per channel.
