Making Connections - REVELL Concerta B12 Owner's Manual

Note
Setting the level of the subwoofer in relation
to the left and right front speakers is of critical
importance because it is essential that the
subwoofer integrate smoothly with the entire
system. Setting the level too high results in
an overpowering bass response. Setting the
level too low negates the benefits of the
B120 subwoofer.
MAKING
CONNECTIONS
CAUTION!
Never make or break
connections unless all system
components are powered off.
Figure 8: Rear-panel input connectors
This section provides typical examples of cable
connections with different system configurations and
devices. Review the owner's manuals for associated
audio components to determine their connection
requirements.
The B120 subwoofer input connectors are located on the
rear panel. Two gold-plated RCA connector options are
available – Sub In Low-Pass Disabled (Normal) and L/R
Low-Pass Enabled – as shown in Figure 8.
In most cases, you'll use the Sub In connector, as it's
designed for multichannel use. This input bypasses the
low-pass filter, and is the appropriate input for most
installations. This connector should be used when there
is a dedicated subwoofer output available on the audio
processor or receiver.
Revel Concerta B120
Owner's Manual
Note
Some processors incorrectly label the subwoofer
output as LFE; others offer both an LFE and
a Subwoofer output. If there is no labeled
subwoofer output, use the LFE output. If the
output has labeled connections for both LFE
and Subwoofer, use the Subwoofer output.
The L (Left) and R (Right) connectors on
the rear panel of the B120 are for use with
2-channel applications, where there is no
dedicated subwoofer output available. These
inputs are automatically crossed-over by the
adjustable Low-Pass Crossover control on the
rear panel. Having the low-pass filter enabled
helps offset the fact that most 2-channel
systems do not perform any high-pass filtering
on the main speakers, minimizing the
advantages of using a subwoofer. These
connectors should be used in 2-channel
applications where the receiver or preamplifier
lacks a dedicated subwoofer or LFE output.
Note
The Concerta B120 subwoofer has a third
connection option – wireless connection is
also available when coupled with the optional
TX1 transmitter. Refer to the "Wireless
Connection" section found later in this manual
for additional details regarding this option.

This configuration is for use with multichannel
processors or receivers that have a single dedicated
Subwoofer or LFE output connector.
Connect the supplied RCA patch cable from the Subwoofer
or LFE output on the processor/receiver to the Sub In
connector on the B120 rear panel, as shown in Figure 9.
