CE2000                                        Standard 1 kHz

4 ohm Stereo (per channel)                                         660 Watts

4 ohm Bridge - Mono                                               1,950 Watts

Standard 1kHz Power: refers to maximum average power in watts at 1 kHz with 0.5% THD.

Load Impedance: Safe with all types of loads. Rated for 4 and 8 ohms in Stereo mode, 4 ohms in Bridge-Mono mode.

Voltage Gain to 1-kHz, 8-ohm rated output:

•      32.1-dB gain at 1.4-volt sensitivity;

•      26-dB gain at 2.83-volt sensitivity.

Required AC Mains: 50/60 Hz (North American units are 60 Hz only); 100, 120 and 230-240 VAC (10%) units are available.

Power Draw At Idle: 90 watts 

AC Line Connector: NEMA 5-15P (15 A).

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.

• Power: A green LED that turns on when the amplifier has been turned on and has power.

Input/Output 

Input Connector (standard module): One Neutrik Combo connector for each channel which features a balanced -inch (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 Connectors: Two Neutrik Speakon NL4MP output connectors (mates with NL4FC). Options for initial-release models CE2000: CE-S1 Speakon to barrier output adapter or CE-S2 Speakon to 5-way binding post adapter.

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.

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-inch rack mount width (EIA RS-310-B), 5.25-inch (13.34-cm) height and 12.25-inch (31.11-cm) depth behind front mounting surface.
