The CPX is an affordable line of amplifiers geared toward the
MI and DJ markets. A tradition of great sound quality, flexibility
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 studios
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 several
applications and serves as a low-cost solution for most
power amplification needs.

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 unexpected
level changes.Transparent in operation, yet very effective for
its designed purpose.Thermal: Amp monitors internal heat sink temperature and temporarily
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.Specifications
