Crest Audio CPA1800 Specifications

CPA1800 power amplifier
description
The Crest Audio CPA1800 professional power amplifier is
designed to achieve unsurpassed sonic performance and long-
term reliability – even when operating under extreme stress
– in touring or fixed installation applications. The CPA1800
provides high power output coupled with true clarity, and is
well-suited for high-powered subwoofers and passive full
range systems.
Absolute sonic accuracy is the hallmark of every Crest ampli-
fier. Bass is solid and defined to the limits of audibility, with
ample current reserves delivered by an "over-engineered"
power supply and advanced Class
width output devices assure detailed, transparent high fre-
quency response. And, thanks to Crest's exclusive
the CPA1800 will drive 2
Ω
in performance.
Construction and Quality Control
The CPA1800 is built exclusively in Crest's own USA manu-
facturing facility, with internal components selected for pre-
miumquality and proven durability. Each modular
subassembly is pre-tested, and once assembled, the CPA1800
receives a rigorous "hot room" burn-in before thorough final
pre-shipment checkout on precision test equipment.

TourClass ® protection circuits
acl active clip limiting prevents speaker damage by
providing gentle gain reduction at the clipping threshold.
igm instantaneous gain modulation monitors speaker loads to
detect conditions that may overstress output devices, allowing safe
operation into difficult impedances.
autoramp gradually increases gain to the attenuator level-
settings when the amplifier is turned on.
Protection features include: short circuit, dc voltage,
comprehensive thermal management, current in-rush turn-
on/off transient, and sub/ultrasonic input.
