Krell FBI
The FBI back panel provides connections for all inputs and out-
puts, power on/off, and additional remote connections.
15 Left and Right Loudspeaker Outputs
Two pairs of loudspeaker binding posts are available for each
channel of amplification, facilitating a power-bi-wire connection to
the loudspeaker. Each pair of binding posts is connected internal-
ly via copper buss bars. When only one set of binding posts is
used, the connection can be made from either pair of binding
posts. See the loudspeaker and/or cable manufacture’s instruc-
tion manual for more information about power-bi-wire connec-
tions.
The loudspeaker binding posts accept spade lugs only. Bare wire,
banana lugs, or pins will not work. Use the red terminal for the
positive connection and the blue terminal for the negative con-
nection.
