Krell Industries EVOLUTION TWO MONAURAL PREAMPLIFIER - Manual (Page 13)

Definition of Terms
Following are the definitions of key terms used in this owner’s reference.
Configurations
CAN Link
The communication system that links multiple Evolution Two preamplifier channels
is a sophisticated system called a controller area network (CAN).
Linked Mode
In linked mode, functions including power, volume, balance, phase, record, mute,
and input selections are instantaneously transmitted between linked preamplifier
channels. Evolution Two preamplifiers use CAN Link to operate in linked mode.
Clone
A method of transmitting custom configurations between linked preamplifier chan-
nels.
Inputs and Outputs
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 profes-
sional and sound recording 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 system
or the environment.
CAST and Evolution CAST
Krell Current Audio Signal Transmission, or CAST, is a proprietary Krell circuit tech-
nology for connecting analog components, transmitting the audio waveform
between components in the current domain rather than in the voltage domain. The
speed and bandwidth provided by Krell CAST and its circuitry update, Evolution
CAST, yield accurate, realistic music reproduction, enabling connected compo-
nents to perform as if they are all part of a single circuit.
Single-ended
A two-wire input or output circuit. Single-ended connections are not recommend-
ed for connections requiring long cable runs. Use care when using single-ended
connections, because the ground connection is made last and broken first. Turn
the system off/on prior to making or breaking single-ended connections.
