Krell CAST

Current Audio Signal Transmission

CAST (Current Audio Signal Transmission) is
a proprietary technology by Krell Industries, LLC that effectively
combines the signal gain stages of components connected in CAST into one
gain block. CAST technology virtually eliminates the noise and
distortions created from the use of multiple voltage gain stages. A
Krell system connected in CAST transfers the signal in the current
domain, throughout the signal path to the amplifier output stage where
only one current to voltage conversion (I-to-V) takes place. CAST
enabled products include a transmitter and receiver circuitry that
transfers current from an extremely high output impedance (source) to a
low-impedance input (load), minimizing the cable's effect on signal
transmission.

 

CAST technology expands the usable
audio signal bandwidth well over 2 MHz; ensuring harmonic reflections
are virtually immeasurable in the audible frequency range. CAST allows
signal transmission over extended lengths of interconnect cable,
allowing flexible placement for your components, without signal
degradation.

 

The 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 components in the system. The cables
that connect the components also have their own electrical
characteristics, which affect the sonic presentation of the entire
system. CAST transmission unifies individual components and
interconnects into an electrically linked whole. The original signal
remains unaltered from source to speaker.

 

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 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 component. With CAST, circuit board properties and
signal transmission aberrations 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 origin 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 transmission to
the next evolutionary level. In essence, Krell Current Mode maintains
the integrity of the signal within the component and CAST preserves the
transmitted signal between components. Together, CAST and Krell Current
Mode technologies unify separate Krell components into a single global
circuit. Krell Current Mode technology enjoys bandwidth increases up to
an order of magnitude greater than their voltage based counterparts.
This dramatic increase in circuit bandwidth delivers near perfection in
the audible band that typically suffers from phase distortions in
voltage circuits.

 

Evolution CAST

By
employing radical current mirror circuitry, the Evolution components
elevate the CAST technology to another level. This advanced use of the
technology increases the linearity, transient speed, and bandwidth of
the Evolution components while reducing the distortion by an order of
magnitude.

 

The Best Musical Performance

When
you operate a CAST system, you will hear significant improvements in
every performance area: speed, precision, dynamic range, depth and width
of the sound stage, transient impact, tonal balance, harmonic
distortion, and more. 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 musical event for you, using the full expression of
technology to date.
