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-set-
tings when the amplifier is turned on. This prevents abrupt turn-on
level.
Other protection features include:
short circuit, dc voltage, com-
prehensive thermal management, current in-rush turn-on/off tran-
sient, and sub/ultrasonic input.
The CD Series amplifier is the next generation family of ele-
vated efficiency amplification from Crest Audio. With sonic
performance the primary priority, the CD Series uses a com-
bination of a linear power supply and a class D output to deliv-
er 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 need-
ed to operate.
