120 Volts: 9.5 A;
230-240 Volts: 5.0 A;

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): 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 2-position switch located on the back panel below the input connectors which, when turned to stereo, operates the amplifier as 2 independent channels. When "Bridge-Mono" mode is selected, the amplifier bridges the 2 output channels for twice the output voltage.
Sensitivity: A 2-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.
Fault: Normally off, this red indicator will blink under 5 different conditions:
When the amplifier is first powered up, until the unit is ready for operation. If the heatsinks reach a temperature above normal working limits. If the transformer thermal protection circuit is activated. If amplifier output wires develop a short-circuit. Should the amplifier output stage become non-operational. This circuit may be monitored remotely by plugging a simple switching circuit using an LED or other signaling device into the back-panel RJ-11 (Fault) jack. Under some conditions, the output of the amplifier will be muted.
Power: A green LED that turns on when the amplifier has been turned on and has power
Input/Output
Input:
Input Connector (standard module): One Neutrik Combo connector for each channel which features a balanced 1/4 in. (6.35-mm) phone jack and a 3-pin female XLR connector, in parallel with a barrier strip termination
Input Stage: Input is electronically balanced and employs precision 1% resistors
Input Impedance: Nominally 20 k ohms, balanced. Nominally 10 k ohms, unbalanced
Input Sensitivity: 1.4 volts for standard 1-kHz power, or fixed 26-dB gain. 0.775-volt sensitivity available (call Crown Technical Support)
Output:
Output Connectors: 2 Neutrik Speakon NL4MP (mates with NL4FC) output connectors. Optional 5-way binding post or barrier strip outputs in parallel with Speakon connectors
DC Output Offset: +/-10 millivolts
Output Signal, Stereo: Unbalanced, 2-channel; Bridge-Mono: Balanced, single-channel. Channel 1 controls are active; Channel 2 should be turned down
Other Specifications and Features
Protection: CE Series amplifiers are protected against shorted, open, or mismatched loads; overloaded power supplies; excessive temperature, chain destruction phenomena, input overload damage, and high-frequency blowups. They also protect loudspeakers from input/output DC, large or dangerous DC offsets, and turn-on/turn-off transients.
Construction: Rugged steel chassis is formed into a durable package any stagehand could love. Coated with environmentally friendly powder for long life and ease of maintenance.
Cooling: Proportional speed fan
Dimensions: EIA Standard 19 in. rack mount width (EIA RS-310-B), 5.25 in. (13.34cm) height and 12.25 in. (31.11cm) depth behind front mounting surface
Weight: The CE 1000 weighs 32.6 lbs. (14.79 kg). The CE 2000 weighs 40.3 pounds (18.28 kg). For shipping weight, add 6 lbs. (2.7 kg) to each amp.
