Definition of Terms Following are the definitions of key terms used in your owner’s ref- erence manual. CONFIGURATIONS Theater Throughput Theater Throughput is a Krell configuration option that allows the signal from a surround preamp/processor to pass through a Krell preamplifier or integrated amplifier with no gain, for integrated vol- ume and balance management of Krell home theater systems. INPUT AND OUTPUT Balanced CONNECTIONS A symmetrical input or output circuit that has equal impedance

Connecting the KAV–300iL to Your System USING BALANCED Krell recommends using balanced interconnect cables. Balanced CONNECTIONS interconnect cables not only can minimize sonic loss but are also immune to induced noise, especially with installations using long cables. Balanced connections have 6 dB more gain than single- ended connections. When level matching is critical, keep this gain value in mind. Follow these steps to connect the KAV–300iL to your system. Connection Steps 1. Make sure all
