Crest CD1500 Amplifier
CREST AUDIO CD1500 Professional Power
Amplifier
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.
