Product Description The Crest Audio PL7001 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. Absolute sonic accuracy is the hallmark of every Crest amplifier. Bass is solid and defined to the limits of audibility, with ample current reserves delivered by an “over-engineered” power supply and advanced Class H circuitry. Wide-bandwidth output devices assure detailed, transparent high frequency response. And, thanks to Crest’s exclusive IGM circuit, the PL7001 will drive 2Ωloads safely without compromise in performance. Construction and Quality Control The PL7001 is built exclusively in Crest’s own USA manufactur- ing facility, with internal components selected for premium qual- ity and proven durability. Each modular subassembly is pre-test- ed, and the assembled PL7001 receives a rigorous “hot room” burn-in before thorough final checkout on precision test equip- ment. PL7001 Features • Crest’s legendary “overbuilt” power supply • Toroidal power transformer • Latest generation of high-speed, wide-bandwidth output devices • Twin tunnel cooling with back-to-front air flow • Dual, variable speed DC fans • Massive, extruded aluminum heat sinks • Balanced XLR and 1/4-inch (TRS) inputs • 5-Way Binding Post Outputs • Stereo/parallel/bridged mono mode selector switch • Ground lift switch • TourClass® protection circuits: - ACL (Active Clip Limiting) prevents speaker damage with gentle gain reduction at clip threshold. - IGM (Instantaneous Gain Modulation) monitors speaker loads to detect conditions that may overstress output devices, allowing safe operation into nominal 2Ωimped- ances. - AutoRamp gradually increases gain to attenuator setting level when amplifier is turned on. - TourClass also includes comprehensive thermal manage- ment, and short circuit, DC voltage, turn-on/off transient, current inrush and sub/ultrasonic input protection. • Input sensitivity selection • Recessed, stepped attenuators • Front panel circuit breaker switch • Modular construction • Three-year warranty 4ΩStereo PL3301 PL4601 PL6001 PL8001 PL9001 1kHz, .01% THD+N 250W 435W 600W 1200W 1800W 20Hz-20kHz, 0.1% THD+N 200W 400W 500W 1100W 1700W Power Specifications: Other PL Series Power Amplifiers PL7001 POWER AMPLIFIER
