the units.
D. CONNECTIONS
Caution: When making connections to this component or any other
always make sure the power amplifier is OFF and the preamplifier is
in the Mute or standby mode.
Install the unit(s) on a clean, level surface away from excessive
heat or moisture.
The Krell B.A.F. can be connected to your system in four different
configurations. Connection details of the four options are presented
below. Follow the instructions that are appropriate for your system.
I. Sinqle unit, sinqle-ended between preamplifier and amplifier(s)
Connect the single-ended output of your preamplifier to the input of
the B.A.F. Connect the output of the B.A.F. to the single-ended input
on your power amplifier(s).
Operate your system in the same manner as before the B.A.F was
installed.
2. Sinqle unit, sinqle-ended, throuqh the preamplifier ~ape loop
Connect the Tape outputs of your preamplifier to the inputs of the
B.A.F. Connect the outputs of the B.A.F. to the Tape inputs of your
preamplifier. Be sure to maintain correct left and right channel
connections.
When listening to the B&W speakers, the Tape Monitor should be set to
the position corresponding to the output return from the B.A.F. The
Input Selector is used to select a source for listening.
Caution: In this configuration the Input Selector must not be set to
the input connected to the B.A.F. output. As with any tape recorder
or surround processor, this will create a feedback loop that can
cause a squeal. At high volume settings this could potentially damage
the loud speakers.

3. Dual units, balance.d, between p~eamplifier and amplifier(s)
Connect the left channel balanced output of your preamplifier to the
balanced input on the left channel B.A.F. Connect the balanced output
of the left B.A.F to the left balanced input of the power amplifier.
Do the same for the right channel.
Operate your system in the same manner as before the B.A.F.s were
installed. ~.~
4. Dual units, balanced or sinqle-~nded, throuqh the preamplifier
tape Ioo~
Connect the left channel Tape output of your preamplifier to the
input of the left channel B.A.F. Do the same for the right channel.
Connect the output of the left channel B.A.F. to the left channel
Tape i or 2 input of your preamplifier. Do the same for the right
channel.
When listening to the B&W speakers, the Tape Monitor should be set to
the position corresponding to the output return from the B.A.F. The
Input Selector is used to select a source for listening.
Caution: With this configuration the Input Selector must meve~ be set
to the input connected to the B.A.F. output. This will create a
feedback loop that can damage other system components.
5. After double-checking the input/output connections, connect the
power cord to the B.A.F.(s) and the other end to an AC outlet. The
unit(s) is now powered and operational.
There is no ON/OFF switch on the B.A.F. It was designed to be left on
at all times. The unit will draw less than i0 watts from the AC
powerline.
6. Turn the other system components on, remembering that the
amplifier is always the last component to be energized.
