Krell S-300i
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 single-
ended connections. When level matching is critical, keep this gain
value in mind.
Follow these steps to connect the S - 3 0 0 i to your system.
1 . Make sure all power sources and components are off before
connecting inputs and outputs.
2 . Neatly organize the wiring between the S - 3 0 0 i and all system
components. Separate AC wires from audio cables to
prevent hum or other unwanted noises from being introduced
into the system.
3 . Connect the left and right loudspeaker cables to the integrated
a m p l i f i e r
’
s left and right loudspeaker output terminals (14).
The S-300i uses standard binding posts for each amplifier
channel. These connectors accept bare wire, pins, bananna
jacks or spade lugs. Use the red terminal for the positive con-
nection and the black terminal for the negative connection.
4. Connect the left and right outputs of your source components to
the appropriate analog inputs (15, 16, 17) on the S-300i.
The S - 3 0 0 i is equipped with one balanced input (B-1), three sin-
gle-ended inputs (S-1, S-2, or S-3), and one iPod input. The B-
1, S-1, S-2, and S-3 inputs can be configured for T h e a t e r
Throughput. See
Optional Configurations
, on page 17 for
information on configuring an input for Theater Throughput.
5 . Use the preamp outputs (19) to connect to an additional power
a m p l i f i e r.
6 . Plug the AC cord into the IEC connector (22) on the back
panel of the S-300i. Plug the remaining end into the AC wall
receptacle. Press the Power Button on the rear panel, The red
stand-by LED (2) illuminates and the display shows the soft-
ware version.
