Crown CL1 |
2-Channel Contractor Series Amplifier |
Looking for a quality, constant voltage and low impedance two channel amplifier for your restaurant, nightclub, retail store, school or house of worship projects? The Crown® “Contractor Series” amplifiers 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) expansion 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 feature/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.
• 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 connectors allow for quick and easy connection, regardless of the load.
• Active crossover with signal routing available with optional System Solution Topology modules.
• 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 reproduction.
• Three-Year, No-Fault, Fully Transferable Warranty 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 amplifier should it fail at any time up to 6 months following date of installation.
Load Impedance:
• 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:
30.5 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%.
AC Line Current:
• 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.
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.
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.
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 amplifi er as two independent channels. When “Bridge” is selected, the amplifi er bridges the two output channels for twice the output voltage.
Indicators
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 amplifier output.
Fault:
A red indicator for each channel which indicates amplifi er has muted output. Normally off. Status may be monitored remotely by plugging into backpanel RJ11 Fault jack.
Power:
A blue indicator that turns on when the amplifi er has been turned on and has power.
