CONFIGURATIONS
Krell Link A method synchronizing remotecontrol operof ation for Krell systems that include multiple preamplifiers, amplifiers, and associated components. When Krell Link in/out connections are used, the remotecapabilities of the linked components are controlled from one component, called the control component. The linked components respond to stand-by and operational mode commands from the control component via MIDI cables. Theater Throughput Theater Throughput is a Krell configuration option that allows the signal from a surround preamp/processor pass through a Krell preto amplifier or integratedamplifier with no gain, for integrated volume and balance management of Krell home theater systems.
INPUT AND OUTPUT CONNECTIONS
Balanced A symmetrical input or output circuit that has equal impedance from both input terminals to a common ground reference point. The industry standard for professional and soundrecording installations, balanced connections have 6 dB more gain than single-ended connections and allow the use of long interconnect cables. Balanced connections are completely immune to induced noise from the systemor the environment.

Revolutionary Krell CAST Technology
Current Audio Signal Transmission, termed CAST, a revolutionary methodof connecting is analog audio components for unparalleled sonic performance. Innovative engineering combines the new Krell CAST circuitry with existing Krell Current Mode technology to create entire CAST systemsthat reproduce music with incredible range, tonality, andprecision. Voltage Signal Transmissionand the Traditional Audio System Traditionally, signal is transmittedin the voltage domain between two components. In an audio system,eachcomponentis a discrete entity with uniquecharacteristics that act uponthe musical signal independently. Each component is unaware the other corn ponentsin the system. of The cables that connect the components each havetheir ownelectrical characteristics, which affect the sonic presentation the entire system. of CAST: A New Approach CAST circuitry recognizessignal transmitted in the current domain instead of the voltage domain between each component. CAST transmission unifies the individual components and their interconnects into an electrically linked whole. Thesonic presentation of the entire system remainsintact. CAST Basics Here's how a CAST audio system works. Internally, each CAST source transfers, or amplifies, current using Krell Current Mode circuitry. This current signal is then output using CAST circuitry. When signal is received by the a CAST input, Krell Current Modecircuitry again takes over until the signal reaches the loudspeaker. By maintaining the musical signal in the current domain from beginningto end, an entire CAST systembehaves if it is one comas ponent. With CAST, anomalies signal transmisof Krell KPS 25sc sion betweencomponents eliminated. Cable are impedances their effects on the transmitted and signal are non-existent. HowCASTand Krell Current ModeInteract While CAST a newmethodof transferring the is musical signal betweencomponents, its orig n stems from Krell Current Mode,the technology developed transfer the musical signal within to a component. CAST combined with Krell Current Modetakes circuitry signal transmission to the next evolutionary level. In essence, Krell CurrentMode maintainsthe integrity of the signal within the component and CASTpreserves the transmitted signal betweencomponents. Together, CAST and Krell Current Mode technologies unify separate Krell components into a single global circuit. CASTCable Construction A CASTsystem uses cables manufactured by Krell and other manufacturers specially licensed by Krell. Thin andflexible CAST cables are constructed with the samebuild quality as other Krell products and are aesthetically matchedto the components that Krell manufactures. An all-metal bodyand locking connectors with gold contacts are part of the standardnocompromise specification developedfor every CASTcable made. The Best Musical Performance Whenyou operate a CASTsystem, you will hear significant improvements every perforin mance area: speed, precision, dynamicrange, depth and width of the soundstage, transient impact, tonal balance, harmonic distortion, and mor.e. The goal for CAST the samecompany is goal usedfor all Krell products.Krell strives for the delivery of the best performance a musiof cal event for you, using the full expressionof technologyto date.

For balanced or single-ended operation, connect the interconnect cables from either the left and right fixed balanced (38), variable balanced (39), fixed single-ended(40), or variable single-ended(41) outputs on the KPS25sc back panel to the balanced or single-endedinputs on your preamplifier or amplifier. (The remaining outputs can be connected another preamplifier or amplito fier in a different system). IMPORTANT Use variable output terminals when the KPS 25sc is connected directly to a Krell stereopower amplifier or to a pair of Krell monaural power amplifiers that do not havegain control Usingfixed outputs can damage poweramplifiers and loudspeakers.
Krell recommends using its proprietary Krell CAST system for unparalleled sonic performancebetween the KPS25sc and other CASTequipped componentssuch as the Full Power Balanced amplifiers or the Master Reference Amplifiers. The KPS25sc also offers balanced operation. The circuitry and connections associated with balancedoperation not only can minimize sonic loss but also are immuneto induced noise, especially for installations using long cables. Follow these steps to connect the KPS25sc to your system. IMPORTANT Connecting non-CAST components to CAST inputs or outputs can damage your equipment and void your warranty.
