20 Krell KAV– 400xi
Q. Should I leave my KAV– 400xi on at all times?
A. Krell recommends leaving the amplifier in the stand-by mode,
ready to play music. If you are not going to play music for a
long time, you may disconnect the amplifier from AC power
supply.
Q. When I turn on the amplifier there is a loud hum through the
loudspeakers. What should I do?
A. When a new component is introduced into a system, a low
frequency hum may occur in one or both loudspeakers. Check
all input and output connections, making sure they are of
sound construction. See
How to Troubleshoot System
Noise , on page 19. If the interconnects and cables are sound,
you may be experiencing a ground loop. This can often be
easily eliminated. Please contact your authorized Krell dealer,
distributor, or Krell for suggestions on how to solve this
problem.
Q. When I use the KAV– 400xi’s Theater Throughput capability
with my surround sound processor, where should I set the
volume on the KAV– 400xi?
A. You do not need to set the volume on the KAV– 400xi because
the amplifier’s volume and balance controls are not active in
the Theater Throughput mode. When using the KAV– 400xi’s
Theater Throughput capability, the surround sound processor
controls the system volume. See
Optional Configurations, on
page 17.
