8 Krell Full Power Balanced X Series Power Amplifiers
The front panel accesses power on/stand-by
and infrared sensor (remote control) functions.
The power stand-by, bias, regulator, and Krell
CAST LEDs, arranged in a triangle on the front
panel above the power button, illuminate to indi-
cate amplifier status.

1 Power Stand-by LED
The blue power stand-by LED (top of LED tri-
angle) illuminates when the back panel power
breaker switch has been moved to on, engag-
ing the input circuitry and placing the amplifier
in stand-by mode.
2 Bias LED
The blue bias LED (lower left of triangle) illumi-
nates after the front panel power button is
pressed, indicating that the Sustained Plateau
Bias III is engaged.
3 Power Button
Use the silver power button to power on the
amplifier from stand-by mode.
4 Infrared Sensor
The infrared sensor receives the signal from a
remote control.
5 Krell CAST LED
The red Krell CAST LED (center of triangle) illu-
minates when a Krell CAST input on the back
panel is connected to another Krell product with
a Krell CAST output.
6 Regulator LED
The blue regulator LED (lower right of triangle)
illuminates after the front panel power button is
used to power on from stand-by mode, indicat-
ing that the regulator is providing power to the
output stage.
Note
An optional remote control is available for Full
Power Balanced amplifiers.
