Description: 4 Amps avaliable. Price is for 1. Amps are all in good working condition. CD 3000 Power Amplifier The CD 3000 3000W Power Amplifier combines a linear power supply and a Class D output to deliver Crest power in a compact and cost-effective package. The CD 3000 is very versatile, whether powering nightclub systems or touring bands.A traditional linear power supply is used in the CD Series. Because of the efficiency of the switching output stage, the transformer does not need to be big or heavy. This gives the CD Series an advantage in delivering huge power in a compact package. The efficiency of the output stage also gives the power supply the ability to handle heavy duty cycles without compromising sonic integrity.Crest Audio's engineering has also maintained sonic quality while incorporating the advantages of a switching output stage. High-power Class-D topology is the key to its efficiency and low operating temperature. An additional advantage is its low power consumption.Features8 Ohm Stereo - 800 W4 Ohm Stereo - 1500 W2 Ohm Stereo - 1800 W8 Ohm Bridged - 3000 WDramatically reduced net weightLinear power supply / Class D output stagesVery low current drawLatest generation of high-speed, mosfet output devicesCooled by variable-speed fan with back-to-front airflowInputs: balanced female XLR, 1/4" TRS combi jacksOutputs: Speakon and five-way binding postsMode selector switch for stereo, parallel and bridged-mono operationGround-lift switch and rear panel circuit breakerRecessed, stepped attenuators with removable knobs16-gauge steel chassis, cast aluminum front panelTourClass protection circuitsACL (Active Clip Limiting) prevents speaker damage by providing gentle gain reduction when signal approaches the clipping thresholdIGM (Instantaneous Gain Modulation) monitors speaker loads to detect conditions that may over-stress output devices, allowing safe operation into nominal 2 Ohm speaker loadsAUTORAMP gradually increases gain to the attenuator level-settings when the amplifier is turned on, preventing abrupt turn-on levelsOther protection features include: short circuit, DC voltage, comprehensive thermal management, current in-rush turn-on/off transient and sub/ultrasonic inputSpecifications:Model: CD 3000Stereo Power 8 Ohms: 800 WattsStereo Power 4 Ohms: 1500 WattsStereo Power 2 Ohm: 1800 WattsBridged Power 8 Ohm: 3000 WattsMaximum output voltage: 85V rmsFrequency response 1W @ 8 ohms: 20Hz?20khz, +/-1dbPower bw rated power @ 4 ohms, 1% THD+N: 20Hz?20khz, +/-1dbTHD + N: <0.2% rated power @ 4 ohms, 1khz power @ 8 ohmsImd; SMPTE/DIN 4:1 (60 Hz / 7 khz): <0.35% @ -3 db below ratedDamping factor: 400:1 @ 8 ohms (20 Hz to 100 Hz)Input CMRR: >60db @ 1khzGain / input sensitivity @ 4 ohms: Selectable: x20, x40, or .775 V for full rated output powerInput impedance: >20kohms balanced, >10kohms unbalancedHum and noise: > -100db, A-weighted below rated power @ 4 ohmsCrosstalk: > -60db below max rated power (1khz)Class: DPower supply: Linear with toroid transformerCircuit breaker rating (120V/230V): 20A /12ACurrent draw (120VAC) 1/8 power, 4 ohms: 7.0A1/3 power, 4 ohms: 14.0AAt idle: 1.5AThermal emissions 1/3 Power, 4 ohms BTU / hr: 1024Cooling: Back to front via variable speed DC faninput connectors: balanced female XLR, 1/4" TRS, unbalanced 1/4" TS on Neutrik combo connectorsoutput connectors: Five-way "touch-proof" binding posts and Neutrik Speakon connectors (which presentsboth outputs on the A Speakon for bi-amplified applications)controls: front panel: twin recessed stepped attenuators, power switchrear panel: signal ground-lift, mode select, gain select, circuit breakerLED indicators: signal level (5 element bargraph), protect, active, ACL / IGMConstruction: 16-gauge steel chassis, cast aluminum front panel - optional handles availableDimensions (W x H x D): 19" x 3.5" x 15.375" (483 x 89 x 391 mm)Weight: 41.4 lb (21 kg)
