HORIZONTAL BI-AMPLIFIED
CONNECTIONS
Horizontal bi-amplified connections are
also made between both F12s and two
separate power amplifiers. The F12 input
connectors labeled HF (High Frequency)
are connected to one power amplifier,
while the F12 input connectors labeled LF
(Low Frequency) are connected to another
power amplifier, which sometimes
improves sonic performance. These power
amplifiers can be identical or dissimilar,
but must have identical “gain factors.” If
the gain factors are dissimilar, a means of
adjusting the input level of at least one
power amplifier is required. Horizontal bi-
amplified connections are shown in Figure
11 (below).
Note
When making horizontal bi-amplified
connections, both power amplifiers must
receive identical input signals from the
associated pre-amplifier. A “Y” adaptor is
required if the associated pre-amplifier
does not offer two connectors per output
channel. Otherwise, each power amplifier
can be connected to a separate connector
for the same output channel of the pre-
amplifier.
To make horizontal bi-amplified
connections:
1. Remove the input panel shorting-straps
identified in Figure 5 (page 9).
2. Connect one pair of loudspeaker wires
to the F12 input connectors labeled HF
(High Frequency) in Figure 11 (below).
Then, connect the same pair of loud-
speaker wires to the desired power
amplifier outputs.
3. Connect another pair of loudspeaker
wires to the F12 input connectors
labeled LF (Low Frequency) as shown
in Figure 11 (below). Then, connect the
same pair of loudspeaker wires to the
desired outputs on another power
amplifier.
4. Repeat step 2 to connect the input con-
nectors labeled HF (High Frequency) as
shown in Figure 11 (below) on the
second F12 to the same power amplifier
that was selected in step 2.
