Crown XLS 402D combine low cost with first-class reliability in addition to a number of significant features : Now housed in rugged, all-steel 2U chassis, the four XLS models employ 2 efficient forced air fans to prevent excessive thermal buildup.

XLS402:  570W at 2 Ohms, 450W at 4 Ohms, 300W at 8 Ohms, 1140W at 4 Ohms Bridge, 900W at 8 Ohms Bridge. 1kHz Power: refers to maximum average power in watts at 1kHz with  0.5% THD

Front panels sport dual, precision detented level controls, a power switch and four LEDs, which indicate clip for each channel, power and fault conditions. Rear panel connections include two electronically balanced XLR inputs, touch-proof binding post outputs as well as a two Speakon outputs, and the top spekcon is wired as a 4 pole output socket for Bridge mode and BI Amp appliactions (Ch1 on pins 1+/1- and Ch2 on pins 2+/2-).

Performance: The following applies to units in Stereo mode with 8-ohm loads unless otherwise specified.

• Sensitivity (volts RMS) for full rated power at 4 ohms: 1.25 V.
• Frequency Response (at 1 watt) 22 Hz to 20 kHz: +0 dB, –0.8 dB.
• Signal-to-Noise Ratio (20 Hz to 20 kHz) A-weighted, below rated power: >98 dB., No weighting, below rated power: >93 dB.
• Total Harmonic Distortion (THD): <0.5%.
• Intermodulation Distortion (IMD): (60 Hz and 7 kHz at 4:1) from full rated output to –40 dB: < 0.3%.
• Damping Factor (8 ohm) 10 Hz to 400 Hz: >200.
• Crosstalk (below rated power) at 1 kHz: –76 dB. at 20 kHz: –58 dB.
• Input Impedance (nominal): 20 kilohms balanced, 10 kilohms unbalanced.
• Load Impedance: Rated for 2 to 8 ohms per channel in Stereo, 4 to 8 ohms in Bridge Mono.
• AC Line Voltage and Frequency  (±10%):  230-240 VAC

Controls

• Level: Two front-panel rotary level controls, one for each channel.
• Power: Front-panel switch; on when in the IN position.
• Circuit Breaker: Back-panel breaker provides overload protection.
• Mode Switch: Back-panel switch selects Dual or Bridge-Mono mode.

Indicators

• Signal Presence Indicators: Two green LEDs, one for each channel, illuminate when the channel’s input signal exceeds –40 dBu.
• Clip Indicators: Two red LEDs, one for each channel, illuminate when the channel’s output is being overdriven.
• Power Indicator: Blue LED indicates amplifier has been turned on and AC power is available.
• Fault Indicator: Two red LEDs illuminate when amplifier is in protect mode. Also illuminates briefly during normal power-up when amplifier is first switched on.

Input/Output

• Input Connectors: One per channel; back-panel three-pin female XLR input connectors.
• Output Connectors: Two 4-Pole Speakon® Output Connectors accept 2-pole or 4-pole Speakon connectors. The top Speakon connector is wired for both channels so it can be used for bridge-mono wiring or for stereo wiring of two speakers to a single Speakon connector. One pair of back-panel binding posts per channel; accepts banana plugs or bare wire. (European models do not accept banana plugs.)

Protection

• XLS Series amplifiers provide extensive protection and diagnostic capabilities, including output current limiting, DC protection, circuit breaker, and thermal protection.

Construction

• Ventilation: Flow-through ventilation from front to back.
• Cooling: Internal heat sinks with forced-air cooling for rapid, uniform heat dissipation.
• Air Volume Requirements (per minute per unit): 80.15 ft³ (2.27 m³).
• Dimensions: EIA Standard 19-inch (48.3-cm) rack mount width (EIA RS-310-B), 3.5-inch (8.9-cm) height and 15.2-inch (38.6-cm) depth.

Crown's Three Year, Full, No-Fault Warranty

Crown offers a Three Year, Full, No-Fault Warranty for every new Crown amplifier—an unsurpassed industry standard. With this unprecedented No-Fault protection, your new Crown amplifier is warranted to meet or exceed original specifications for the first three years of ownership. During this time, if your amplifier fails, or does not perform to original specifications, it will be repaired or replaced at our expense. About the only things not covered by this warranty are those losses normally covered by insurance and intentional abuse. And the coverage is transferable should you sell your amplifier.
