[. . . ] 7002 power amplifier
description
The Pro II Series heralds a major advance in amplifier design from Crest Audio. [. . . ] 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, providing maximum output power, while drawing significantly smaller peak currents from the AC line. Compared with an amplifier using a conventional power-supply, 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.

PowerLok technology dramatically reduced net weight latest generation of high-speed, wide-bandwidth output devices twin-tunnel cooling with back-to-front air flow four, rear-mounted, continuously-variable-speed fans balanced male and female xlr inputs with switch-configurable xlr polarity and sensitivity selection Speakon and five-way binding post output connectors stereo, parallel, bridged-mono: mode selector switch ground-lift switch front panel power switch, rear panel circuit-breaker recessed, stepped attenuators modular construction aluminum chassis five-year warranty
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 speaker loads. autoramp gradually increases gain to the attenuator levelsettings when the amplifier is turned on. Other protection features include: short circuit, dc voltage, comprehensive thermal management, current in-rush turnon/off transient, and sub/ultrasonic input.
