T ECHNOLOGIES& I NNOVATIONS Krell Industries, Inc. designs and manufactures high performance audio and video equipment for serious music enthusiasts and home theater aficionados. Ev ery Krell component is a unique syn - thesis of science and art that allo ws for unmatched sonic real - ism. Recorded performances are, b y their very nature, works borne of passion. Our goal is to bring that passion to life in your home. Kr ell Evolution Series products represent the supreme realization of Krell design and engineering. The Evolution One amplifier and Evolution Two preamplifier are the result of o ver 25 years in the pursuit of the ultimate listening experience. The formidable engi - neering efforts required to bring Evolution products into existence extend to the Class A and KAV series components making for unpar alleled performance in their classes. Kr ell Class A Series components are performance leaders in their respecti ve product categories. Class A power amplifier design has been a Krell tradition since the compan ys inception in 1980.

Krell Architec h Construction Krell Ar chitec h construction is a Krell mechanical design criteri - on that ensures each Krell product meets the highest standards of structur al integrity. Chassis material of robust, heavy gauge alu - minum provides long life and durability as well as a distincti ve look and feel. High tolerance machining and liberal use of flight- certified fasteners reduce or eliminate undesirable vibr ations. Built to last a lifetime, Krell products with Architec h construction enhance your listening experience every time you use them. Kr ell CAST II C AST , Current Audio Signal Transmission, is a Krell proprietary tec hnology for connecting analog components that provides the most accurate signal transfer from one component to the next. It utilizes the sonic purity of current and eliminates signal degr ada- tion caused by cable interaction while transmitting signals in v oltage. CAST II greatly increases the input stage bandwidth of the Full P ower Balanced X Series amplifiers. Kr ell Current Mode A topology designed by Krell and used in amplifier, preamplifier , and source components circuitry to ensure accurate signal repro - duction. Realizing the entire design in the current domain elimi - nates the sonic degrading nature of circuit boards and increases the o ver all band width. The greater bandwidth, all Krell compo -nents ha ve a bandwidth greater than 300KHz, results in near fla wless reproduction in the audible r ange. Sustained Plateau Bias III A patented microprocessor control system that maintains Class A bias operation regardless of musical demand. Class A bias is the most accurate method used to amplify musical signals. T he new Sustained Plateau Bias III software maximizes an ampli - fier s efficiency both in power consumption and heat gener ation, and is featured in the Full P ower Balanced X Series amplifiers. T heater Throughpu t T he unique Theater Throughpu tfeature facilitates easy integr a- tion of Krell stereo preamplifiers and integrated amplifiers into home theater systems. In Theater Throughput mode, the main output signal from an external surround sound processor b ypass- es the volume and balance controls, providing a direct connec - tion to the amplifiers powering the front left and right speakers. Kr ellcoat F inish F or o ver 25 years, Krell has been designing components that set the standard not only for audio engineering but also for inno va- ti ve aesthetic design. Krells experience and knowledge has been distilled into a new process called Krellcoat finish. Krellcoat fin - ish gi ves Krell components a look that is timeless, with a feel that is inviting and built to last. On the co ver: Evolution Two preamplifier with diamond-cut silver finish, in the operational mode. F eaturing incomparable build quality and superior circuit topolo - gies, Class A products are the driving force of reference quality audio systems w orldwide. Kr ell KAV Series products incorporate the core elements of Krell engineering to deli ver the highest quality and performance demanded by toda ys dynamic market. The KAV 400xi and SA CD Standard are leaders of a complete series of audio and video components that deli ver Krell performance and outstand - ing value for contemporary home entertainment systems. T he introduction of the upgraded Krell LAT Series loudspeakers dr amatically impro ves an already recognized world-class loud - speaker arr ay. T he Resolution Series source design elements directly from the LAT Series to offer unmatched performance in their class. When coupled to the reference quality D VD Standard, the HTS 7.1 surround preamp/processor, and the appropriate Krell amplifiers, my vision of a complete, totally inte - gr ated, Krell home entertainment system is realized. From input to output, from source to loudspeakers, Krell components repro - duce the definiti ve music and home theater experience based on the principles of inno vati ve engineering, impeccable build quali - ty , and unerring accur acy in sonic reproduction.
