Crown CE1000 CE Series Amplifier

CROWN CE1000 Details

CE 1000 and CE 2000
OVERVIEW

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. Plus, your investment in a CE amplifier is backed by Crown's unequaled Three Year, No-Fault, Full Warranty that covers everything.

Compare the new CE 1000 and CE 2000 head-to-head with the competition and hear for yourself why Crown is the only serious choice for audio professionals.

Handles 2-ohm loads

Front-panel detented level controls

Function indicators, fan-assisted cooling, short-circuit protection

Works with SST modules that provide extra functions

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,
CE 1000:
30.5-dB gain at 1.4-volt sensitivity;
26-dB gain at 2.34-volt sensitivity.
CE 2000:
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:
CE 1000/2000: >100 dB.
CE 4000: > 102 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.
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 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 ¼-inch (6.35-mm) phone jack and a 3-pin female XLR connector, in parallel with a barrier strip termination.

Input Stage: Input is electronicall y 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: Two Neutrik® Speakon® NL4MP output connectors (mates with NL4FC). Options for initial-release models CE 1000/2000: CE-S1 Speakon to barrier output adapter or CE-S2 Speakon to 5-way binding post adapter. Options for current CE models
CE 1000A/2000A/2000TX/1000B/2000B (model number on serial no. label): CEAS1 barrier block module or CEAS2 5-way binding post module, both in parallel with Speakon connectors.

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.

Weight:
