impedanceis added due to long cable lengths, amplifier poweris wastedin the cable. Long speaker cables reduce the maximumpowerthat can be delivered to the speakers.

1.Connectthe cables from your speakers to theoutputterminalsof theamplifier.

TheKAV-250aamplifier utilizes five- waybinding post speakerterminals for the left andright channelsThe.speaker terminalsacceptspadelugs, barewire, bananaplugs, or pins. Theredterminals are usedfor positive connectionsand the blackterminalsareusedfor the neg- ative connections.

2.Connectthe interconnect cables from yourpreamplifierto the inputterminalsof theamplifier.

For best performance,Krell ®recommends usinga dedicatedACpowerline rated at a minimumof fifteen ampswith the KAV-250a amplifier. For maximumpoweroutput, the KAV-250ashould be operatedfrom a dedi- cated twenty ampAC power line. The KAV-250aamplifier shouldonly be operated with the powercordsupplied.Pleaseconsult
