Definition of Terms
Following are the definitions of key terms used in your owner’s reference manual.
Inputs and Outputs
Balanced
A symmetrical input or output circuit that has equal impedance from both input ter-
minals to a common ground reference point. The industry standard for professional
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 envi-
ronment.
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 components to perform
as if they are all part of a single circuit.
Operation
Off
When the power breaker switch on the back panel of the power supply is in the
down position, and the power/stand-by LEDs (4), the backlight (5), and the power
meter scale (6) are not illuminated, the amplifier is off.
Stand-by
A low power consumption status that keeps the audio and regulator circuits at idle.
The power/stand-by LEDs (4) are illuminated in red, when the amplifier is in the
stand-by mode. Krell recommends leaving the amplifier in the stand-by mode when
it is not playing music.
