Krell Showcase Processor
Following are the definitions of key terms used in your owner’s refer-
ence manual:
Balanced
A symmetrical input or output circuit that has equal impedance from
both input terminals to a common ground reference point. The indus-
try standard for professional and sound recording installations, bal-
anced connections have 6 dB more gain than single-ended connec-
tions and allow the use of long interconnect cables. Balanced con-
nections are immune to induced noise from the system or the envi-
ronment.
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 single-ended connec-
tions. Single-ended connections are not recommended for connec-
tions requiring long cable runs.
Off
When the power switch on the back panel is placed in the down
position and LEDs turn off, the component is off.
Stand-by Mode
When the Showcase Processor is connected to AC power and the
back panel power switch is in the up (on) position, the red stand-by
LED illuminates. This indicates that the component is in stand-by
mode, 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.
Operational Mode
When the component is in the stand-by mode, and you press the
power button on the front panel or the power key on the remote
control, the blue power LED illuminates. The component is in the
operational mode and is ready to play music.
