XLS Series Overview
The XLS Series of power amplifiers from Crown represents a new era in affordable, quality power amplification. The line consists of three models in a uniform, rugged chassis, incorporating the best of tried-and-true design principles and innovative features. XLS Series amplifiers are professional stereo power amplifiers engineered to meet demanding audio requirements—reliably and within budget. Plus, every XLS Series amplifier is backed by Crown’s unequaled Three-Year, No-Fault, Fully-Transferrable Warranty that covers everything. With over five decades of experience designing and building rock-solid products, Crown is the standard in amp technology. So check out the affordable, Crown XLS Series. They are a powerful argument for quality and value!
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 protects loudspeakers from being overdriven.
* Housed in a rugged, all-steel 2U 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 indicate clip for each channel, power and fault conditions.
* Three-Year, No-Fault, Fully Transferable Warranty completely protects your investment and guarantees its specifications.

Power
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%): 120VAC, 60 Hz and 230VAC, 50 Hz.
Controls
Level: Two front-panel, black rotary level controls, one for each channel.
Power: Front-panel switch; on when in the UP position.
Circuit Breaker: Provides overload protection.
Indicators
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/Output
Input Connectors: One per channel; back-panel three-pin female XLR input connectors.
Input Impedance: (nominally balanced, nominally unbalanced): 20 k ohms, 10 k ohms.
Output Connectors: One 4-pole Speakon® connector and one pair of back-panel, 5-way binding posts per channel; accepts banana plugs, spade lugs or bare wire. (European models do not accept banana plugs.)
DC Output Offset (shorted input): ±10 millivolts.
Output Signal: Stereo, unbalanced, two-channel.
Protection
XLS Series amplifiers provide extensive protection, including output current limiting, DC protection, circuit breaker, and special thermal protection for the unit’s transformers.
Construction
