Current Audio Signal Transmission (CAST) is a proprietary Krell
circuit technology for connecting analog components, in which
the audio waveform is transmitted between components in the
current rather than the voltage domain. The speed and band-
width that CAST provides yield astounding levels of accuracy
and realism. Krell components connected via CAST perform as
if they are all part of a single circuit.
LFE enriches the low end of a musical score and enhances
nearly subsonic content, such as explosions or other special
effects. It is part of the Dolby 5.1 specification, with a bandwidth
of 5 to 120 Hz.
A two-wire input or output circuit in which the ground connection
is made last and broken first. Use care when using single-ended
connections. Turn the system off prior to making or breaking
single-ended connections. Single-ended connections are not
recommended for configurations requiring long cable runs.
Operation
When the power switch on the rear panel is placed in the down
position and the red stand-by LED turns off, the component is off.
When the power button on the front panel is pressed and the
blue power LED illuminates, the component is in the opera-
tional mode and ready to play music.
A low power consumption status that keeps the audio and reg-
ulator circuits at idle. Krell recommends leaving the component
in the stand-by mode when it is not playing music.
Technology
A proprietary Krell circuit designed to continuously compare the
position of a loudspeaker to the analog waveform at the amplifier
input. Active Motion Control provides an extra measure of
loudspeaker control without the transient distortion associated
with simple servo designs.
