Questions and Answers

Q.Should I leave my KAV–280p on all the time?

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 20. 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–280p’s Theater Throughput capability with my surround sound processor, where should I set the volume on the KAV–280p?

A.You do not need to set the volume on the KAV–280p because the preamplifier’s volume and balance controls are not active in the Theater Throughput mode. When using the KAV–280p’s Theater Throughput capability, the surround sound processor controls the system volume. See Configuring the KAV–280p for Theater Throughput, on page 19.
