CROWN CE-4000 AMPLIFIER Like Crown's patented, award-winning Balanced Current Amplifier (BCA) technology .BCA gives the Crown CE 4000 superior power output with increased efficiency plus legendary Crown sound and reliability. In stress tests, the CE 4000 continued to perform at levels 12 dB into clip long after other brands had shut down! Flexibility is unsurpassed thanks to features like selectable on-board high- and low-pass filter sets, optional signal control modules,and dual output connectors. CE 4000 MAJOR FEATURES Patented and award winning, Crown's Balanced Current Amplifier (BCA) switching technology iThe Crown CE 4000 is the result of over 30 years of Crown amplifier design experience. And it's the best of all worlds thanks to unique features s an engineering advancement. BCA will generate more power and less heat than traditional linear amplifiers Crown's Switching Mode Power Supply allows enormous power and performance with much less weight-it's only 34 pounds! Power Factor Correction ( PFC ) for global power compatibility means your CE 4000 will work with any line voltage The Crown CE 4000 delivers 1800 watts per channel (both driven) into 2 ohms, 1200 watts into 4 ohms, and 600 watts into 8 ohms-now that's powerful. 2800 watts 4-Ohms Bridge-Mono. (1 Khz Power refers to maximum average power in watts at 1Khz with 0.5% THD).Compatible with Crown's system solutions topologies (SST) input modules for adding flexibility Choice of three duel output connector modules (CE4D,CE4C and CE4E) CE 4000 SPECIFICATIONS Power Load Impedance: Safe with all types of loads. Rated for 2, 4 and 8 ohms in Stereo mode, 4 and 8 ohms in Bridge-Mono mode. Voltage Gain to 1-kHz, 8-ohm rated output: 39.0-dB gain at 0.775-volt sensitivity; 33.8-dB gain at 1.4-volt sensitivity; 26-dB gain at 3.46-volt sensitivity.Required AC Mains: 50/60 Hz, 100-240VAC (±10%). AC Line Current, 100 Volts: 100 Volts: 8.5 A; 120 Volts: 7.1 A; 230-240 Volts: 3.7 A; At Idle: Amp draws no more than 140 watts.AC Line Connector. Frequency Response: ±0.25 dB from 20 Hz to 20 kHz at 1 watt.Phase Response: ±15 degrees deviation from linear phase from 20 Hz to 20 kHz at 1 watt. Signal to Noise Ratio, A-Weighted, 20 Hz to 20 kHz: Better than 102 dB below rated 1-kHz power;Total Harmonic Distortion (THD): 1-kHz rated power, 0.5% or less THD from 20 Hz to 20 kHz. Intermodulation Distortion (IMD): (60 Hz and 7 kHz at 4:1) Less than 0.5% at rated power to 30 dB below rated power at 8 ohms. Damping Factor: Greater than 700 from 10 Hz to 400 Hz.* Crosstalk: Better than 50 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 & Connectors Level: A 31-step 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 three-position switch located on the back panel next to the Mode switch. Switchable among 0.775 volts or 1.4 volts for full output into an 8-ohm load (default setting), or 3.46 volts for a fixed voltage gain of 26 dB. Fault Jack: A back-panel RJ-11 jack that may be remotely monitored to signal amplifier Fault condition. An LED or other signaling device (not supplied) may be used. Filter Switches: Low Pass: A three-position switch for each channel located on the back panel below the input and output modules. Switchable among settings for Flat, 80 Hz and 100 Hz. Filter roll-off is 24-dB per octave. High Pass: A four-position switch for each channel located on the back panel below the input and output modules. Switchable among settings for Flat, 30 Hz, 40 Hz and 50 Hz. Filter roll-off is 18-dB per octave. Indicators: A green LED for each channel which flashes when a very low-level signal (>–40 dBm) is present at input. Clip: A red LED for each channel which turns on when distortion becomes audible in the amplifier output. Normally off, this red indicator will blink under five 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: Input Connector (standard module): One Neutrik(R) Combo connector for each channel which features a balanced 1/4-inch (6.35-mm) phone jack and a 3- pin female XLR connector, in parallel with a barrier strip termination. Input/Output Input Stage: Input is electronically balanced and employs precision 1% resistors. Input Sensitivity: 0.775 volts or 1.4 volts for standard 1-kHz power, or fixed 26- dB gain. Output Connectors: Three options available: Four (4) Neutrik Speakon(R) NL4MP (mates with NL4FC)output connectors; two (2) 5-way binding posts in parallel with two (2) Speakon connectors; or barrier strip outputs in parallel with two (2) 5-way binding posts.Output Signal, Stereo: Unbalanced, two-channel; Bridge-Mono: Balanced, single-channel. Channel 1 controls are active; Channel 2 should be turned down. Protection: CE 4000 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.
