 “Contractor Series” 

amplifi ers are designed just for you.

CL Series amplifi ers provide 2, 4 and 8 ohm options 
per channel for applications where high power, low 
impedance loads are the primary requirement.

All Contractor Series amplifi ers feature Crown’s 
exclusive SST (System Solutions Topologies) expan-
sion system. The SST expansion system makes it 
easy to tailor your amplifi er to a specifi c application 
or to add future technology as it develops.

With an incredibly wide range of power and fea-
ture/benefi ts, Contractor Series amplifi ers give the 
professional sound contractor more options. Crown 
quality is available at the best dollar-per-watt ratio on 
the market.

For more details about the Crown Contractor Series, 
contact the Crown Technical Support Group at 800-
342-6939 or 574-294-8200. Also, visit the Crown 
Audio website at www.crownaudio.com.

Note: All measurements apply to amplifi ers in stereo 
mode with 8-ohm loads and an input sensitivity 
of 26-dB gain, 1-kHz at rated power unless other 
otherwise specifi ed. Specifi cations  for units supplied 
outside the U.S.A. may vary slightly at different AC 
voltages and frequencies.

Output Power: See power charts below.

Load Impedance:
Safe with all types of loads. 

2, 4 and 8 ohm Stereo.
4, 8 and 16 ohm Bridge. 

30.5 dB (CL1), 32.1 dB (CL2), or 34 dB (CL4) into 
8 ohms.

AC Line Requirements:
Note: North American units are 60 Hz only. All other 
models are 50/60 Hz. Voltages are ±10%.

100V: 7.6A (CL1), 11.4A (CL2), or 8.5A (CL4).
120V: 6.3A (CL1), 9.5A (CL2), or 7.1A (CL4).
230-240V: 3.5A (CL1), 5.0A (CL2), or 3.7A (CL4).

AC Line Connector: Detachable 15A IEC connector 
with country-specifi c plug. 

Frequency Response, 20 Hz to 20 kHz at 1 watt: 
±0.1 dB (CL1, CL2) or ±0.25 dB (CL4).

Phase Response: ±15 degrees deviation from linear 
phase from 20 Hz to 20 kHz at 1 watt.

Signal to Noise Ratio, A-Weighted: Better than 105 
dB (CL1, CL2) or 102 dB (CL4) below rated 1-kHz 
power.  

Total Harmonic Distortion (THD), 1 kHz at rated 
power: 0.5% or less true THD from 20 Hz to 20 kHz.

Intermodulation Distortion (60 Hz and 7 kHz at 4:1): 
Less than 0.1% (CL1, CL2) or 0.5% (CL4) at rated 
power to 30 dB below rated power at 8 ohms.

Damping Factor (8 ohm): Better than 400 (CL1, CL2) 
or 700 (CL4) from 10 Hz  to 400 Hz.

Crosstalk, 20 Hz to 20 kHz: Better than 50 dB below 
rated power.

Common Mode Rejection (CMR): Better than 40 dB 
from 20 Hz to 1 kHz.

DC Output Offset (shorted input): < ±10 mV.

Level: A detented rotary level control for each channel 
located on the rear panel.

Power: An on/off rocker switch located on the front 
panel.

Mode: A two-position switch located on the back 
panel which, when turned to “Stereo,” operates 
the amplifi er as two independent channels. When 
“Bridge” is selected, the amplifi er bridges the two 
output channels for twice the output voltage.

Signal: A green indicator for each channel which 
fl ashes when a very low-level signal (> –40 dBm) is 
present at input. May be used for troubleshooting 
cable runs.

Clip: A red indicator for each channel which turns 
on when distortion becomes audible in the amplifi er 
output.

Fault: A red indicator for each channel which indi-
cates amplifi er has muted output. Normally off. Status 
may be monitored remotely by plugging into back-
panel RJ11 Fault jack. 

Power: A blue indicator that turns on when the ampli-
fi er has been turned on and has power. 

•  Low impedance compatibility for applications 

where high power, low impedance loads are 
the primary requirement.

•  Rear panel detented level controls allow for 

accurate level settings and secure operation.

•  “Contractor-Correct” barrier strip output con-

nectors allow for quick and easy connection, 
regardless of the load.

•  Active crossover with signal routing available 

with optional System Solution Topology mod-
ules.

•  5-Way Fault Indicator serves as a valuable 

system troubleshooting aid by quickly alerting 
the user of potential problems.

•  Advanced protection circuitry guards against: 

shorted outputs, open circuits, mismatched 

loads, DC, general overheating, high-frequency 
overloads and internal faults.

•  Can be mounted in standard (19-inch (48.3-

cm)) rack, shallow (14-inch (35.56-cm)) rack, 
or stacked on top of each other.

•  Accurate, uncolored sound with very low 

distortion for the best in music and voice repro-
duction.

•  Three-Year, No-Fault, Fully Transferable War-

ranty completely protects your investment and 
guarantees its specifi cations.

•    Crown’s Profi t Protection Plan guarantees 

quick, no-questions-asked replacement of your 
covered Contractor Series amplifi er should it 
fail at any time up to 6 months following date 
of installation.
