Crown XLS 402 Pro Power Amplifier 400W 4 Ohms

  
Incredibly powerful Crown XLS 402 Pro Amplifier perfect for live or studio applications. From a smoke free environment. Power your speakers with a classic amp and hear the difference. Simple, reliable design incorporates many popular features. Selectable high-pass filter on each channel enables amplifier to work more efficiently when full band-width is not required. Pair of linear optocoupler clip limiters pro-tects loudspeakers from being overdriven.

Housed in a rugged, all-steel 3U chassis. Efficient forced-air fan prevents excessive thermal buildup. Electronically balanced XLR inputs and touch-proof binding post outputs.

Features precision detented level controls, power switch, and four LEDs, which indi-cate clip for each channel, power and fault conditions. The following applies to units in Stereo mode with 8-ohm loads and rated input sensitivity unless otherwise specified. Sensitivity (volts RMS) for full rated power at 4 ohms: 1.025.

Frequency Response (at 1 watt) 20 Hz to 20 kHz: ±0.75 dB. Phase Response (degrees at 1 watt). Signal-to-Noise Ratio (20 Hz to 20 kHz). Total Harmonic Distortion (THD) at full band-width power, from 20 Hz to 1 kHz.

Intermodulation Distortion (IMD): (60 Hz and 7 kHz at 4:1) from full rated output to -40 dB. Damping Factor (8 ohm) 10 Hz to 400 Hz: >200. At 1 kHz: -82 dB. At 20 kHz: -58 dB.

Voltage Gain (at maximum output): 31 dB. Load Impedance: Safe with all types of loads. Rated for 2 to 8 ohms in Stereo, 8 ohms in Bridge-Mono. AC Line Voltages Available (±10%): 120 and 230 VAC. Level: Two front-panel, black rotary level controls, one for each channel.

Power: Front-panel switch; on when in the UP position. Filter Switches: One per channel; three-posi-tion back-panel switches set the frequency for internal high-pass filters. Frequency setting is 30 Hz when switch is in left position; 15 Hz when switch is centered; and bypassed when switch is in right position.

Limiter Switch: Back-panel switch offers loud-speaker protection against moderate amplifier clip when set to the "IN" position. Clip: Two front-panel red LEDs, one for each channel, illuminate when the channel's output signal is being overdriven. Power: Green front-panel LED indicates amplifier has been turned on and AC power is available.

Fault: Yellow front-panel LED illuminates when amplifier is in protect mode. Also illuminates briefly during normal power-up when amplifier is first switched on.

Input Connectors: One per channel; back-panel three-pin female XLR input connectors are provided. Input Impedance (nominally balanced, nomi-nally unbalanced): 20 k ohms, 10 k ohms. Output Connectors: One pair of back-panel, 5-way binding posts per channel; accepts banana plugs, spade lugs or bare wire. Euro-pean models do not accept banana plugs. DC Output Offset (shorted input): ±10 millivolts. Output Signal: Stereo, unbalanced, two-channel.
