Krell Evolution Two Brochure

Page 1

The Evolution Series culminates more than two decades of cutting edge audio design. When envisioning Evolution, Krell had one solitary goal – to hand craft a preamplifi er and power amplifi er that, simply put, were the best sounding products ever built. The result is a synthesis of almost impossible contradictions; a unique blend of beauty, grace, and the effortless power synonymous with the Krell name. Evolution One Amplifi er The Evolution One is a Class A, 450-watt monaural amplifi er that utilizes proprietary current gain topologies from input to output allowing the audio signal to remain in the current domain throughout the entire amplifi er thereby avoiding unnecessary current to voltage conversions that add distortion, require heavy feedback and severely limit bandwidth. The Evolution One circuitry is virtually devoid of feedback and sports a bandwidth an order of magnitude greater than any conventional design. Coupled to this circuitry is a power section that is virtually limitless in its capability to drive any speaker to its full potential. With all of this unrestricted power on tap, the Evolution One employs advanced microprocessors that constantly monitor operating conditions and can automatically adjust the operating parameters or shut the amplifi er down to prevent damage to the input stages or loudspeakers. $50,000 Evolution Two Preamplifi er The Evolution Two monaural preamplifi er is a Class A design that was built to absolute perfection inside and out. The audio signal path operates in full balanced mode from input to output and the proprietary Krell CAST inputs further ensure absolute integrity of the audio signal. Nothing was overlooked when designing the Evolution Two; not even the volume control that features a 16-bit balanced resistor ladder which uses low-resistance, high-linearity solid-state switches and discrete precision resistors for the purest line stage possible. Although the Evolution Two embraces the simplistic pleasures of a high-end two channel preamp, it also features sophisticated RS-232, IR and 12-volt controls for better integration into a state-of-the-art home environment. $40,000 Ferrari and Cartier say you enjoy luxury and know quality. Krell says you never compromise.
