Revolutionary Krell CAST
Technology
Current Audio Signal Transmission, termed
CAST, is a revolutionary method of connecting
analog audio components for unparalleled
sonic performance. Innovative engineering
combines the new Krell CAST circuitry with
existing Krell Current Mode technology to cre-
ate 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 com ponent is a discrete entity with
unique characteristics that act upon the musical
signal independently. Each component is
unaware of the other corn ponents 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 trans-
mission unifies the individual components and
their interconnects into an electrically linked
whole. The sonic presentation of the entire sys-
tem 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 maintaining the musical signal
in the current domain from beginning to end, an
entire CAST system behaves as if it is one com-
ponent. With CAST, anomalies of signal transmis-
sion between components are eliminated. Cable
impedances and their effects on the transmitted
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 orig n
stems from Krell Current Mode, the technology
developed to transfer the musical signal within
a component. CAST combined with Krell
Current Mode takes circuitry signal transmis-
sion to the next evolutionary level. In essence,
Krell Current Mode maintains the integrity of the
signal within the component and CAST pre-
serves the transmitted signal between compo-
nents. Together, CAST and Krell Current Mode
technologies unify separate Krell components
into a single global circuit.
CAST Cable Construction
A CAST system uses cables manufactured by
Krell and other manufacturers specially
licensed by Krell. Thin and flexible CAST cables
are constructed with the same build quality as
other Krell products and are aesthetically
matched to the components that Krell manufac-
tures. An all-metal body and locking connectors
with gold contacts are part of the standard no-
compromise specification developed for every
CAST cable made.
The Best Musical Performance
When you operate a CAST system, you will
hear significant improvements in every perfor-
mance area: speed, precision, dynamic range,
depth and width of the sound stage, transient
impact, tonal balance, harmonic distortion, and
mor.e. The goal for CAST is the same company
goal used for all Krell products. Krell strives for
the delivery of the best performance of a musi-
cal event for you, using the full expression of
technology to date.
