Owner’s Manual
MAKING
CONNECTIONS
The F12 features gold-plated binding posts
and shorting-straps that allow it to be
configured for single-wired, bi-wired or bi-
amplified connections.
CAUTION
• Never make or break connections
unless all system components are
powered off.
• Remove the input panel shorting-straps
identified in Figure 5 (page 9) before
making bi-wired or bi-amplified
connections. Failure to do so may cause
damage to some power amplifiers.
Before making connections, note the
following:
• Make all connections observing the
proper polarity, positive-to-positive (+)
and negative-to-negative (–).
Connections that do not observe the
proper polarity will cause poor stereo
imaging and diminished bass response.
• The standard connection method uses
a single loudspeaker wire. The F12 is
equipped with two pairs of input termi-
nals to allow for bi-wiring or bi-ampli-
fication. While we do not endorse one
particular connection method over
another, these additional connection
options are available if desired. The
design of this loudspeaker is such that
optimal performance can be attained
using the standard connection method.
• Vertical bi-amplified connections must
be made with identical power amplifiers.
Horizontal bi-amplified connections
can be made with identical or dissimi-
lar power amplifiers with identical
“gain factors.”
• When making bi-amplified connections,
both power amplifiers must receive
identical input signals from the associ-
ated 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.
• Use high-quality loudspeaker cable
with a maximum total loop resistance
of 0.07ohms or less (for each wire run).
Refer to the table below to determine
the appropriate maximum wire gauge.
Maximum Wire Gauge

Note
High loop resistances that exceed 0.07ohms
(for each wire run) will cause the filter
network to mis-terminate, resulting in
considerable degradation of sound quality.
• Review the owner’s manuals for
associated audio components to
determine their connection procedures.
• If you have questions about the suit-
ability of associated power amplifier com-
ponents, contact an authorized Revel
dealer for information.
