Question and Answer

Q. ShouldI leave the KAV-250aor KAV-250a/3amplifier on at all times?

A. No. Theseamplifiers do not havea stand-bymode.Leavingthemon at all times wouldresult in considerableheat output andpowerconsumptionFor. best results, turn the amplifier off whennot in use, andallow a five minutewarm-upafter it is turnedon. SeeAmplifier Operation, on page25.

QoWhenI turn the amplifier on there is a loud humthrough the loudspeakers.What should I do?

A. Whena newcomponentis introduced, a low frequency hummayoccur in one or both loudspeakers.Checkall input andoutput connectionsandcables, makingsure they are of soundconstruction. SeeHowto Troubleshoot SystemNoise, on page 26. If the connectionsandcables are sound,you maybe experiencinga groundloop. This canoften be easily eliminated.Pleasecontact your authorizedKrell dealer, distributor, or Krell for suggestionson howto solve this problem.

Q. WhenI connectthe amplifier to mysystemusing the single-endedinputs, a loud buzz comesfrom myloudspeakers.Is the amplifier broken?
