Definition of Terms
Following are the definitions of key terms used in your owner’s
reference manual.
Theater Throughput
Theater Throughput is a Krell configuration option that allows the
signal from a surround preamp/processor to pass through a Krell
preamplifier or integrated amplifier input at unity gain and sus-
pends operation of the preamp volume control. When Theater
Throughput is employed, control of the volume is accomplished
through the home theater processor.
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 sound recording instal-
lations, 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 technology 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 components to perform as if
they are all part of a single circuit.
Single-ended
A two-wire input or output circuit. Use care when using single-
ended connections as the ground connection is made last and
broken first. Turn the system off prior to making or breaking sin-
gle-ended connections. Single-ended connections are not recom-
mended for connections requiring long cable runs.
