Crown XTi 4002 Power Amplifier

• Stereo, 2 ohms (per ch.): 1600W
• Stereo, 4 ohms (per ch.): 1200W
• Stereo, 8 ohms (per ch.): 650W
• Bridge-Mono, 8 ohms: 2400W
• Bridge-Mono, 4 ohms: 3200W

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.
• Peak x Plus Limiter: user defeatable limiter that allows users to control Threshold, Attack, and Release times.
• Presets: 30 total presets, 29 of which are user-definable.

Performance

• Operating Temperature: 0C to 40C at 95% relative humidity (non-condensing)

Controls</<strong>Level: two front-panel rotary level controls, one for each channelPower Switch: On/Off switch applies AC power to the amplifierSel/Prev/Next Buttons: three buttons near the LCD screen that are used to access menu items and front panel lockoutLCD 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).
• -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, illuminates under excessive temperature conditions
• Power Indicator: Blue LED illuminates when the amplifier has been turned on and has power

Input/Output Connectors
