Product Description

From the Manufacturer

If you've spent any time at all in professional audio, you know the name Crown and what it stands for--incredible performance and sound, the ultimate in reliability under harsh conditions and the best support in the business. These are just a few of the reasons why the world's biggest tours and most prestigious installations have Crown amps in their racks. And now, with the introduction of the new CE Series, we're bringing what sets Crown professional amplifiers apart from all others to a very affordable price range.

CE Series amplifiers are professional tools designed and built for professional use. Engineered and manufactured by the same teams who build our acclaimed Macro-Tech and K Series amps, the new CE 1000 and CE 2000 have the rugged heart and soul that has characterized our amplifiers for over 30 years. Rather than make a cheap amplifier and hang all sorts of semiprofessional features on it, we focused on providing powerful, reliable performance with many of the same controls and features you've come to expect from Crown. You'll find front panel detented level controls, useful function indicators, proportional fan-assisted cooling, short circuit protection and more. And, to make the amplifier more flexible to the way that you work, we've provided a new SST (System Solution Topologies) module which allows you to customize the amplifier with true professional features such as fixed-point crossover cards.

The result is an amplifier capable of chest-thumping lows that easily handles real 2-ohm loads and runs longer under difficult conditions than any competitive amp out there. The CE2000 is rated at 975W (2-ohm stereo), 660W (4-ohm stereo), 400W (8-ohm stereo), 1950W (8-ohm bridge mono), 1320W (4-ohm bridge mono).

Key Features

Accurate, uncolored sound with very low distortion for the best in music and voice reproduction.
Bridge-mono/stereo mode switch allows you to set up your amps/speakers in the configuration that best suits your needs.
Advanced protection circuitry guards against: shorted outputs, open circuits, DC, mismatched loads, general overheating, high-frequency overloads and internal faults.
Extremely versatile, handling a wide range of speaker impedances and outputs.
Switchable input sensitivity.
Proportional speed fan optimizes cooling efficiency.
Shallow rack depth. Only 12.25 inches deep!
Choice of Speakon, binding post, or barrier strip outputs (Speakon comes standard).
Choice of balanced 1/4-inch (6.35-mm), XLR, or barrier strip inputs.
The best Three-Year, No-Fault, Fully Transferable Warranty in the business! It even covers round-trip ground shipping in the U.S. for all warranty work.

Performance

Frequency Response: 0.2 dB from 20 Hz to 20 kHz at 1 watt.
Phase Response: 15 degrees from 20 Hz to 20 kHz at 1 watt.
Signal to Noise Ratio (below rated power), 20 Hz to 20 kHz: >100 dB.
Total Harmonic Distortion (THD): 1-kHz rated power, 0.5% or less true THD from 20 Hz to 20 kHz.
Intermodulation Distortion (IMD): (60 Hz and 7 kHz at 4:1) Less than 0.1% at rated power to 35 dB below rated power at 8 ohms.
Damping Factor: Greater than 400 from 10 Hz to 400 Hz.
Crosstalk: Better than 55 dB below rated power, 20 Hz to 20 kHz.
Common Mode Rejection (CMR): Better than 70 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 front panel.
Power: An on/off rocker switch located on the front panel.
Mode: Turn power off before switching. A two-position switch located on the back panel below the input connectors which, when turned to stereo, operates the amplifier as two independent channels. When "Bridge-Mono" mode is selected, the amplifier bridges the two output channels for twice the output voltage.
Sensitivity: A two-position switch located on the back panel next to the Mode switch. Switchable between 1.4 volts for full output into an 8-ohm load (default setting), or a fixed voltage gain of 26 dB.
Indicators Signal: A green LED 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 LED for each channel which turns on when distortion becomes audible in the amplifier output.
