ooking for a quality, constant voltage and low Limpedance two channel amplifier for your res- taurant, nightclub, retail store, school or house
of worship projects? The Crown® “Contractor Series” amplifiers are designed just for you.
CL Series amplifiers provide 2, 4 and 8 ohm options per channel for applications where high power, low impedance loads are the primary requirement.
All Contractor Series amplifiers feature Crown’s exclusive SST (System Solutions Topologies) expan- sion system. The SST expansion system makes it easy to tailor your amplifier to a specific application or to add future technology as it develops.
With an incredibly wide range of power and fea- ture/benefits, Contractor Series amplifiers give the professional sound contractor more options. Crown quality is available at the best dollar-per-watt ratio on the market.

Specifications
Note: All measurements apply to amplifiers in stereo mode with 8-ohm loads and an input sensitivity
of 26-dB gain, 1-kHz at rated power unless other otherwise specified. Specifications for units supplied outside the U.S.A. may vary slightly at different AC voltages and frequencies.
Power
Output Power: See power charts below.
Load Impedance:
AC Line Connector: Detachable 15A IEC connector with country-specific plug.
Performance
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.
Controls
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 amplifier as two independent channels. When “Bridge” is selected, the amplifier bridges the two output channels for twice the output voltage.
Safe with all types of loads.
2, 4 and 8 ohm Stereo. 4, 8 and 16 ohm Bridge.
Voltage Gain, 1 kHz, 1.4V sensitivity:
30.5dB (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%.
AC Line Current:
100V: 7.6A (CL1), 11.4A (CL2), or 8.5A (CL4).

Indicators
Signal: A green indicator for each channel which flashes 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 amplifier output.
Fault: A red indicator for each channel which indi- cates amplifier 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- fier has been turned on and has power.
