Introduction Thank you for your purchase of the Krell KAV–300iL Remote Control Integrated Amplifier. This fully integrated amplifier and pre- amplifier has a fully balanced signal path from input to output and employs a wide bandwidth design with low negative feedback for sonic accuracy throughout the frequency spectrum. All circuits up to the driver stage are pure Class A. Krell’s new surface mount technology (SMT) means that the KAV–300iL is an integrated amplifier with big power—200 Watts pe

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
