MAKING CONNECTIONS
CAUTION: Never make or break connections unless all system components are
powered off.
OBSERVE PROPER POLARITY
Connect the amplifier’s positive (+) terminal to the positive (+) terminal on the loudspeaker;
connect the amplifier’s negative (–) terminal to the negative (–) terminal on the loudspeaker.
Do not reverse polarities (that is, do not connect + to –, or – to +) when making connections.
Doing so will cause diminished dialog intelligibility and diminished bass response.
SPEAKER CABLE
Use high-quality loudspeaker cable with a maximum total loop resistance of 0.07 ohms or
less for each wire run. Refer to the table below to determine the appropriate wire gauge for
your installation.
MINIMUM WIRE GAUGE
Maximum Wire
Length (Feet)
Maximum Wire
Length (Meters)
Minimum Wire
Gauge (AWG)
< 87 < 27 6
< 69 < 21 7
< 58 < 18 8
< 43 < 13 9
< 34 < 10 10
< 27 < 8 11
< 22 < 7 12
< 17 < 5 13
< 14 < 4 14
< 11 < 3.5 15
< 9 < 3 16
< 7 < 2 17
< 5 < 1.5 18
Note: High loop resistances that exceed 0.07 ohms (for each wire run) will cause the
loudspeaker’s filter network to be mis-terminated, resulting in considerable degradation
of sound quality.
CAUTION: Revel C426Be loudspeakers are designed to be used with an external
crossover (high-pass filter), such as is found in the center channel outputs of surround
processors and audio/video receivers. An 80Hz crossover frequency is ideal, and will
minimize dynamic compression and distortion. If desired, the C426Be may be used
with crossover frequencies as low as 50Hz.
If the AVR/processor only offers “Large” and “Small” settings for the center channel,
select the “Small” setting.
C426Be CONNECTIONS
The C426Be features gold-plated binding posts that allow single-wire connection.

Connector Panel
Before making connections to the C426Be, note the following:
• The standard connection method uses a single loudspeaker cable. The C426Be is
equipped with two pairs of input terminals to allow for bi-wiring or bi-amping. While
Revel does 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.
• When making bi-amped connections, both power amplifier channels must receive
identical input signals from the associated preamplifier. If the associated preamplifier
does not offer two connectors for the center channel, a “Y” adaptor is required.
• If desired, contact your authorized Revel dealer for information about the suitability of
power amplifier components before connecting the C426Be to your power amplifier(s).
• Review the owner’s manuals for all associated audio components to determine their
correct connection procedures.
