His exploration of technologies, driven by his never-endingquest to elevate the standard of excellence, has resulted in break- through audio designs. Over the years, the Krell line of power amplifiers, including benchmark products such as the KRS -100,KRS -200,and the Audio Standard models, has established a legacy of unparalleled sonic performance. The Master Reference Subwoofer brings that level of performance to the low frequency range Revolutionary Krell CAST Technology A New Approach Current Audio Signal TransmissionThe Basics of CAST CAST Cables CAST and Krell Current Mode CombinedThe Best Musical Performance Ensuring Maximum Performance Innovative Subwoofer Technology and DesignProgrammable Electronic Crossover Krell Active Motion ControlEnclosure DriversKrell CAST and Krell Current Mode Krell Core TechnologiesKrell Proprietary Output Devices Totally Balanced Operation SECTION ONE About Krell continued Totally Balanced Operation continuedDefinition of Terms ConfigurationsInputs and Outputs Technology OperationKrell Active Motion Control Krell Current Mode A proprietary Krell circuit topology in which the audio gain stages operate in the current domain.
