The CD 1500 is very versatile, whether powering nightclub systems or high school gymnasiums. \u003c\/div\u003e \u003cdiv\u003e \u003c\/div\u003e \u003cdiv\u003eA 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 amps an advantage in delivering huge power in a compact, rackmount package. The efficiency of the output stage also gives the power supply the ability to handle heavy duty cycles without compromising sonic integrity.\u003c\/div\u003e \u003cdiv\u003e \u003c\/div\u003e \u003cdiv\u003eCrest 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 to the CD 1500's design is the amount of power needed over time. This amplifier will dramatically reduce the number of kW\/hr needed for operation.\u003c\/div\u003e \u003cdiv\u003e \u003c\/div\u003e \u003cdiv\u003e\u003cspan style=\"font-weight: bold; text-decoration: underline;\"\u003eFeatures\u003c\/span\u003e\u003c\/div\u003e \u003cdiv\u003e \u003cul\u003e \u003cli\u003eDramatically reduced net weight\u003c\/li\u003e \u003cli\u003eLinear power supply \/ Class D output stages\u003c\/li\u003e \u003cli\u003eVery low current draw\u003c\/li\u003e \u003cli\u003eLatest generation of high-speed, mosfet output devices\u003c\/li\u003e \u003cli\u003eCooled by variable-speed fan with back-to-front airflow\u003c\/li\u003e \u003cli\u003eInputs: balanced female XLR, 1\/4\" TRS combi jacks\u003c\/li\u003e \u003cli\u003eOutputs: Speakon and five-way binding posts\u003c\/li\u003e \u003cli\u003eMode selector switch for stereo, parallel and bridged-mono operation\u003c\/li\u003e \u003cli\u003eGround-lift switch and rear panel circuit breaker\u003c\/li\u003e \u003cli\u003eRecessed, stepped attenuators with removable knobs\u003c\/li\u003e \u003cli\u003e16-gauge steel chassis, cast aluminum front panel\u003c\/li\u003e \u003cli\u003eTourClass protection circuits\u003c\/li\u003e \u003cli\u003eACL (Active Clip Limiting) prevents speaker damage by providing gentle gain reduction when signal approaches the clipping threshold\u003c\/li\u003e \u003cli\u003eIGM (Instantaneous Gain Modulation) monitors speaker loads to detect conditions that may over-stress output devices, allowing safe operation into nominal 2 Ohm speaker loads\u003c\/li\u003e \u003cli\u003eAUTORAMP gradually increases gain to the attenuator level-settings when the amplifier is turned on, preventing abrupt turn-on levels\u003c\/li\u003e \u003cli\u003eOther protection features include: short circuit, DC voltage, comprehensive thermal management, current in-rush turn-on\/off transient and sub\/ultrasonic input\u003c\/li\u003e \u003cli\u003eFive-year warranty\u003c\/li\u003e \u003c\/ul\u003e \u003c\/div\u003e \u003cdiv\u003e\u003cspan style=\"font-weight: bold;
