Revolutionary Krell CAST Technology
Current Audio Signal Transmission, termed CAST,is a revolutionary methodof connecting analog audio components for unparalleled sonic performance. Innovative engineering combinesthe newKrell CASTcircuitry with existing Krell Current Modetechnologyto cre- ate entire CASTsystemsthat reproduce music with incredible range,tonality, andprecision.
Voltage Signal Transmissionand the Traditional AudioSystem
Traditionally, signal is transmittedin the voltage domainbetween two components. In an audio system,eachcomponentis a discrete entity with uniquecharacteristics that act uponthe musical signal independently. Each component is unawareof the other corn ponentsin the system. Thecables that connect the componentseach havetheir ownelectrical characteristics, which affect the sonic presentationof the entire system.
CAST: A New Approach
CASTcircuitry recognizessignal transmitted in the current domain instead of the voltage domainbetween each component. CASTtrans- mission unifies the individual componentsand their interconnects into an electrically linked whole. Thesonic presentationof the entire sys- temremainsintact.
CAST Basics
Here's how a CASTaudio system works. Internally, each CASTsource transfers, or amplifies, current using Krell Current Modecir- cuitry. This current signal is then output using CASTcircuitry. Whenthe signal is received by a CASTinput, Krell Current Modecircuitry again takes over until the signal reachesthe loudspeaker.By maintaining the musical signal in the current domainfrom beginningto end, an entire CASTsystembehavesas if it is onecom- ponent. WithCAST,anomaliesof signal transmis-

HowCASTand Krell Current ModeInteract
While CASTis a newmethodof transferring the musical signal betweencomponents,its orig n stemsfrom Krell Current Mode,the technology developedto transfer the musicalsignal within a component. CAST combined with Krell Current Modetakes circuitry signal transmis- sion to the next evolutionary level. In essence, Krell CurrentModemaintainsthe integrity of the signal within the componentand CASTpre- serves the transmitted signal betweencompo- nents. Together, CASTand Krell Current Mode technologies unify separate Krell components into a single globalcircuit.
CASTCable Construction
A CASTsystem uses cables manufactured by Krell and other manufacturers specially licensed by Krell. Thin andflexible CASTcables are constructed with the samebuild quality as other Krell products and are aesthetically matchedto the componentsthat Krell manufac- tures.
The Best Musical Performance
Whenyou operate a CASTsystem, you will hear significant improvementsin every perfor- mancearea: speed, precision, dynamicrange, depth and width of the soundstage, transient impact, tonal balance, harmonicdistortion, and mor.e. Thegoal for CASTis the samecompany goal usedfor all Krell products.Krell strives for the delivery of the best performanceof a musi- cal event for you, using the full expressionof technologyto date.
