Crown IT 8000

Crown IT 8000 Description:

The world has seen many good amplifiers, but few achieve greatness. What sets these elite few apart from all the others? The answer is simple: A careful synthesis of unrivaled sonic performance combined with rock-solid dependability.

While the definition of a great amplifier may be simple, delivering on those requirements is not. This is what has always set Crown amplifiers apart from the others: Crown delivers.

From the slightest nuances in the tremolo of a flute to the chest pounding bass of a rock 'n' roll kick drum to the harmonic rich vocals of a jazz singer, Crown delivers. Crown amplifiers are renowned for their ability to accurately amplify anything audio-with unmatched power and accuracy-night after night without fail.

For decades, the formula for creating great amplifiers has been the same at Crown: An insightful combination of genetics, breakthrough technologies, craftsmanship, and passion. This formula, proven over and over, has produced a lineage of great amplifiers: DC-300, PSA-2, Micro-Tech® , Macro-Tech® , Studio Reference™ , K, and CTs: Each amplifier great in its time, and each raising the standard for high performance. Once again, this formula for greatness has delivered on its promise: I-Tech, the world's next great amplifier, and the pinnacle of Crown's 50-year history of innovation.

Crown IT 8000 Features:

• 1 Class-I - Interleave Technology
• I-Tech's patented Interleave switch-mode design delivers a solid combination of high output power and a smaller, lighter weight package. Officially designated "Class-I," this break-through technology provides a clear advantage over conventional amplifier (Class-D) models by providing lower distortion, higher voltage, higher power, and greater reliability.
• 2 Industry's Highest Output Voltage
• Today's high-performance loudspeakers need additional voltage drive to really come alive. I-Tech features the highest output-voltage capability of any professional amplifier.
• 3 Regulated Switch-Mode Power Supply
• An all-new, ground-breaking power supply forms the heart of the I-Tech Series. Crown's regulated switch-mode power supply delivers full power regardless of mains voltage: from 120 to 277 volts, and from 50 to 60 Hz.
• 4 PFC (Power Factor Correction)
• Crown's innovative PFC technology allows I-Tech to draw current from the mains in a more controlled and efficient way than non-PFC amplifiers, providing massive amounts of power from a single 20 amp breaker.
• 5 Digital Audio Inputs
• (AES/EBU - CobraNetTM)
• I-Tech amplifiers feature digital audio inputs for exceptional audio quality. With AES/EBU inputs (standard) or optional CobraNet version, I-Tech provides your choice of today's most widely accepted digital audio formats.
• 6 Light Weight
• I-Tech packs a lot of power in a small but rugged, 2U package. Weighing in at less than 28 lbs. (12.7 kg), I-Tech delivers unmatched power for its weight class, far outpacing the competition in watts/pound.
