Revolutionary Krell CAST
and CAST II Technology
4
Current Audio Signal Transmission, termed CAST, is a revolutionary
method of connecting analog audio components for unparalleled
sonic performance. CAST circuitry, and the CAST circuitry update,
Krell CAST II, combine innovative engineering with existing Krell
Current Mode technology to create entire CAST systems that
reproduce music with incredible range, tonality, and precision.
Voltage Signal Transmission
and the Traditional Audio System
Traditionally, signal is transmitted in the voltage domain between
two components. In an audio system, each component is a discrete
entity with unique characteristics that act upon the musical signal
independently. Each component is unaware of the other compo-
nents in the system. The cables that connect the components each
have their own electrical characteristics, which affect the sonic
presentation of the entire system.
CAST: A New Approach
CAST circuitry recognizes signal transmitted in the current domain
instead of the voltage domain between each component. CAST
transmission unifies the individual components and their intercon-
nects into an electrically linked whole. The sonic presentation of the
entire system remains intact.
CAST Basics
Here's how a CAST audio system works. Internally, each CAST
source transfers, or amplifies, current using Krell Current Mode cir-
cuitry. This current signal is then output using CAST circuitry. When
the signal is received by a CAST input, Krell Current Mode circuitry
again takes over until the signal reaches the loudspeaker. By main-
taining the musical signal in the current domain from beginning to
end, an entire CAST II system behaves as if it is one component.
With CAST, anomalies of signal transmission between components
are eliminated. Cable impedances and their effects on the transmit-
ted signal are non-existent.
How CAST and Krell Current Mode Interact
While CAST is a new method of transferring the musical signal
between components, its origin stems from Krell Current Mode, the
technology developed to transfer the musical signal within a com-
ponent. CAST combined with Krell Current Mode takes circuitry
signal transmission to the next evolutionary level. In essence, Krell
Current Mode maintains the integrity of the signal within the compo-
