The Crest Audio CD Series amplifier is the next generation family of elevated efficiency amplification from Crest Audio. With sonic performance the primary priority, the Crest Audio CD1500 amplifier uses a combination of a linear power supply and a class D output to deliver Crest Power in a compact and cost-effective package.

A full complement of features and power-points makes this series very versatile, whether powering nightclub systems or high school gymnasiums. The CD series amplifiers bring a new generation of amplification to Crest Audio.

Linear-toroid power supply
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 as big or as heavy. This gives the CD Series an advantage in delivering more power in a more compact package. The efficiency of the output stage also gives the power supply the ability to handle heavy-duty cycles without compromising sonic integrity.

Switching output stage
Crest Audio’s engineering has maintained sonic quality while incorporating the advantages of a switching output stage. The high-power class D topology is the key to its efficiency and low operating temperature. An additional advantage to this design is the amount of power needed over time. This amplifier will dramatically reduce the number of kW / hr needed

TourClass® protection circuits

- ACL (Active Clip Limiting) prevents speaker damage by providing gentle gain reduction when signal approaches the clipping threshold.

- IGM (Instantaneous Gain Modulation) monitors speaker loads to detect conditions that may overstress output devices. This allows safe operation into nominal 2 ohm speaker loads.

- AUTORAMP gradually increases gain to the attenuator level-settings when the amplifier is turned on. This prevents abrupt turn-on level.

- Other protection features include: short circuit, dc voltage, comprehensive
thermal management, current in-rush turn-on/off transient, and sub/ultrasonic input.
