Crest Audio PRO II SERIES 8002 Specification Sheet

8002 power amplifier
description
The Pro II Series heralds a major advance in amplifier design
from Crest Audio. Extreme reliability and hallmark sonic accu-
racy of the legendary Professional Series is maintained in the
same rugged package—but at only half the weight. Such dra-
matic weight savings are made possible by PowerLok, a radical
new power-supply technology that provides significant perfor-
mance and flexibility advances over conventional designs.
PowerLok is Crest Audio's unique implementation of Power
Factor Correction, which allows current to be drawn
throughout the entire cycle of the AC line-frequency, provid-
ing maximum output power, while drawing significantly
smaller peak currents from the AC line.
Compared with an amplifier using a conventional power-sup-
ply, PowerLok requires less peak power to produce identical
output power results—and because PowerLok's current peaks
are smaller, a Pro II amplifier can be serviced by a lower-rated
breaker than a conventional amplifier of similar wattage.
superior sound quality
excellent low frequency and transient response
louder than conventional amplifiers
—maximum output level never dips
constant, predictable performance
consistent power output
accepts any line voltage worldwide—50 or 60Hz
accepts long power cable runs with no loss of output power
draws significantly less peak current
lighter-duty power distribution components
low line-voltage distortion
minimal supply-ripple
cost-effective
extreme reliability
reduced shipping costs—half the weight of conventional amplifiers

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 nominal 2
autoramp gradually increases gain to the attenuator level-
settings when the amplifier is turned on.
Other protection features include: short circuit, dc voltage,
comprehensive thermal management, current in-rush turn-
on/off transient, and sub/ultrasonic input.
