20 Krell FBI
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 FBI 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 FBI 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 outputs of your source components
to the appropriate analog inputs (15, 16, 17) on the FBI. The
FBI is equipped with one CAST input (C-1) (16), one balanced
input (B-1) (17), three single-ended inputs (S-1, S-2, or S-3)
(18), and one tape input (19). The C-1, B-1, S-1, S-2, and S-3
inputs can be configur
ed for Theater Throughput.
See
Optional Configurations, on page 23 for information on con-
figuring an input for Theater Throughput.

4. Connect the loudspeaker cables to the loudspeaker binding
posts (15) of the FBI, located on the back panel. Loudspeaker
binding posts accept spade lugs only.
6. Plug the AC power cord into the IEC connector (25) on the
back panel of the FBI. Plug the other end of the power cord
into the AC wall receptacle.
