he XLS Series of power amplifiers from
Crown represents a new era in affordable,
quality power amplification. The line con-
sists 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 demand-
ing 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
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 pow-
erful argument for quality and value!

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: 1.26.
Frequency Response (at 1 watt) 20 Hz to 20
kHz: ±0.75 dB.
Phase Response (degrees at 1 watt)
at 10 Hz: –10.
at 20 kHz: +19.
Signal-to-Noise Ratio (20 Hz to 20 kHz)
A-weighted, below rated power: > 100 dB.
No weighting, below rated power: > 97 dB.
Total Harmonic Distortion (THD) at full band-
width power, from 20 Hz to 1 kHz: < 0.15%.
Intermodulation Distortion (IMD): (60 Hz and
7 kHz at 4:1) from full rated output to –40 dB:

• Simple, reliable design incorporates many
• 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
Damping Factor (8 ohm) 10 Hz to 400 Hz: >200.
Crosstalk (below rated power)
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
AC Line Voltages Available (±10%): 120 and
Line Frequency: 50/60 Hz.
• 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
• Three-Year, No-Fault, Fully-Transferrable
Warranty completely protects your invest-
ment and guarantees its specifications.
Level: Two front-panel, black rotary level
controls, one for each channel.
Power: Front-panel switch; on when in the UP
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.
Fuse: Provides overload protection.
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
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.
