When powering up your system, turn the amplifiers on last. When
powering down your system, turn amplifiers off first. The proce-
dures for amplifier operation follow.
1. Plug the end of the AC power cord into the AC wall outlet.
2. The red stand-by LED (2) illuminates.
When the amplifier is first plugged in, there is a brief delay before
it can be put in the operational mode. Please wait approximately
10 seconds.
If the red LED flashes when the amplifier is in the stand-by mode,
unplug the amplifier from the AC wall outlet to reset the protection
circuit. Check the loudspeakers and loudspeaker cables for poten-
tial short circuits before plugging the amplifier back into the wall
outlet.
3. Press the power button (1) on the front panel. The blue power
LED (3) illuminates and you hear a click. The amplifier is in
the operational mode.
Krell recommends leaving the Showcase Amplifier in the stand-by
mode unless you will not be playing music for a long time.
Always turn the amplifier off before changing input connections,
and mute or fully attenuate the preamplifier level when switching
sources.
The Showcase Amplifier has tremendous reserves of power and
safely drives loudspeakers to extremely high sound pressure lev-
els. However, use care when setting high playback levels and lower
the volume level at any sign of loudspeaker distress.
