CE-SERIES
CE 2000
he CE-Series of Crown amplifiers are professional tools designed and built for professional use. Engineered and manufactured by the same teams who built Crown's acclaimed Macro-Tech(R) and KSeries amps, the CE 2000 has the rugged heart and soul that have characterized Crown's amplifiers for over 30 years. With many of the same controls and features you've come to expect from Crown, CESeries amplifiers feature front-panel detented level controls, useful function indicators, proportional fan-assisted cooling, shortcircuit protection and more. For superior flexibility, Crown CE-Series amplfiers can work with a range of Crown SST (System Solution Topologies) modules which provide true professional features like fixed-point crossover and summed bass output. With a powerful, reliable performance, CESeries amps easily handle real 2-ohm loads and are capable of chest-thumping lows. Plus, your investment in an CE-Series amplifier is backed by Crown's unequaled ThreeYear, No-Fault, Fully Transferable Warranty that covers everything. For more details about the Crown CE-Series, contact the Crown Technical Support Group at 800-342-6939 or 219-294-8200. Also, visit the Crown Audio website at www.crownaudio.com.

Controls and Connectors
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: 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 "BridgeMono" mode is selected, the amplifier bridges the two output channels for twice the output voltage. Reset: A front-panel push button used to reset the circuit breaker that protects the power supply. 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. 0.775-volt sensitivity available as a Service Option. Fault Jack: A back-panel RJ-11 jack that may be remotely monitored to signal amplifier Fault condition. An LED or other signalling device (not supplied) may be used.
Specifications
Note: All measurements relate to 120-volt, 60-Hz units in Stereo mode with 8-ohm loads and an input sensitivity of 26dB gain at 1-kHz rated power unless otherwise specified. Specifications for units supplied outside the U.S.A. may vary slightly at different AC voltages and frequencies.
Performance
Frequency Response: 0.2 dB from 20 Hz to 25 kHz at 1 watt. Phase Response: 15 degrees from 20 Hz to 20 kHz at 1 watt. Signal to Noise Ratio, A-Weighted: Better than 105 dB below rated 1-kHz power; 20 Hz to 20 kHz: Better than 100 dB below rated 1-kHz power. Total Harmonic Distortion (THD): 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: Better than 400 from 10 Hz to 400 Hz. Crosstalk: Better than 55 dB below rated power, 20 Hz to 20 kHz.

Output Power:
Indicators
(all located on front panel) 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.

Fault: Normally off, this red indicator will blink under five different conditions:
1. When the amplifier is first powered up, until the unit is ready for operation. 2. If the heatsinks reach a temperature above normal working limits. 3. If the transformer thermal protection circuit is activated. 4. If amplifier output wires develop a short-circuit. 5. Should the amplifier output stage become nonoperational.
Output Connectors: Two Neutrik(R) Speakon(R) NL4MP (mates with NL4FC) output connectors. Optional 5-way binding post or barrier strip outputs (in parallel with Speakon(R) connectors) are available. DC Output Offset: 10 millivolts. Output Signal, Stereo: Unbalanced, two-channel; Bridge-Mono: Balanced, single-channel. Channel 1 controls are active; Channel 2 should be turned down.

Crown's Three-Year, No-Fault, Fully Transferable Warranty
Crown offers a Three-Year, No-Fault, Fully Transferable Warranty for every new Crown amplifier--an unsurpassed industry standard. With this unprecedented No-Fault protection, your new Crown amplifier is warranted to meet or exceed original specifications for the first three years of ownership. During this time, if your amplifier fails, or does not perform to original specifications, it will be repaired or replaced at our expense. About the only things not covered by this warranty are those losses normally covered by insurance and those caused by intentional abuse. And the coverage is transferable, should you sell your amplifier. See your authorized Crown dealer for full warranty disclosure and details. For customers outside of the USA, please contact your authorized Crown distributor for warranty information or call 219-294-8200.
