Protection Circuitry
GCL (Gain Comparator Limiting): Monitors input/output gain and
reduces signal when distortion or excessive high current conditions
occur. Protects loudspeakers from dangerous transients and unex-
pected level changes. Transparent in operation, yet very effective for
its designed purpose.
Thermal: Amp monitors internal heat sink temperature and tem-
porarily shuts down during extreme thermal conditions.
DC Triac Crowbar: Prevents amplifier from putting out or receiving
dangerous DC over the speaker lines.
Turn On/Off Muting: Outputs are muted during turn on and turn off
to prevent audible pop through speakers.
The CPX is an affordable line of amplifiers geared toward the
MI and DJ markets. A tradition of great sound quality, flexibili-
ty and reliability is carried over into the Crest Performance
series. Industry standard connectors and features make the
CPX a great backbone for mobile sound systems, project stu-
dios and many other applications. Musicians will also find
CPX as the power amp of choice.
Power points: Crest CPX amps are available in three models,
CPX900, CPX1500 and CPX2600. Power capabilities range
from 180 Watts to 2200 Watts. CPX amps will drive loads that
range from 8 Ohms stereo to 2 Ohms stereo, or 4 Ohms
bridged.
Feature set: With a comprehensive set of features including
built-in signal limiting, low pass filters and low frequency
crossovers with direct outputs, the CPX line addresses sever-
al applications and serves as a low-cost solution for most
power amplification needs.
