Introduction Thank you for your purchase of the Krell S-300i Remote Control Integrated Amplifier. This fully integrated amplifier and preamplifier has a discrete 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 balanced and pure Class A.
Definition of Terms Following are the definitions of key terms used in your owner’s reference 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 volume and balance management of Krell home theater systems.
Definition of Terms, continued OPERATION Off The component is off when the rear panel button is not depressed. Stand-by Mode A low power consumption status that keeps the audio circuits at idle. When you press the rear panel power button, the red standby LED illuminates. The component is now ready to be switched to the operational mode. Krell recommends leaving the component in the stand-by mode when it is not playing music.

Connecting the S-300i to Your System USING BALANCED CONNECTIONS Krell recommends using balanced interconnect cables. Balanced 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 singleended connections. When level matching is critical, keep this gain value in mind. Connection Steps Follow these steps to connect the S-300i to your system. 1.

How to Troubleshoot System Noise AC grounding becomes critical when connecting high performance audio components. When you mix and match audio components, each with its own ground potential, a low frequency hum may occur in one or both loudspeakers. This sometimes occurs when introducing a new component into a system. If a low frequency hum emanates from the loudspeakers when you place the S-300i amplifier into the system, follow these simple troubleshooting steps: 1.
Questions and Answers Q. Should I leave myS - 3 0 0 i on at all times? 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 turn off the rear panel power button. 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.
