DUAL SUBWOOFER CONNECTIONS
Connection Using High-Level (Speaker Wire) Inputs: Instead of running both speaker cables from your receiver or
amplifi er to the left and right high-level terminals on the subwoofer, you will run the left channel to the left chan-
nel subwoofer and the right channel to the right channel subwoofer. Again, take care to make red to red (+) and
black to black (-) terminal connections. For further setup instructions, refer to Fine Tuning section further below.
Connection using low-level Inputs: From your receiver or preamp, attach a RCA-type “Y” connector to the
Sub/LFE out (unless your receiver or processor has two Sub outs) and then run an RCA-type interconnect cable
to each subwoofer’s low-level input. In this setup, main speaker connections are made between your receiver
or amplifi er in a traditional manner. For further setup instructions, refer to Bass Management Systems Setup
section below.
BASS MANAGEMENT SYSTEMS SET UP (FOR MULTI-CHANNEL, 5.1, ETC., SYSTEMS)
Multi-channel surround sound systems have a critical speaker setup and channel balancing procedure for
setting the level for all speakers and how bass is directed which must be followed if the system is to perform
properly. Many problems relating to the overall sound of the system can be clearly traced back to improper
system balance. Also note that multi-channel surround sound systems have bass management systems which
vary from unit to unit. This bass management system must be properly adjusted. Many problems relating to the
overall sound of the system can be traced back to improper bass management settings.
Bass Management Settings when using High-Level (Speaker-Wire) Input: On your receiver or A/V processor’s
Speaker Setup Menu*, set Left and Right main speakers to “Large” and set Subwoofer to “No” to direct all bass
and LFE information to L/R Main Speakers – and therefore the Sub(s).
Bass Management Settings when using Low-Level (Sub/LFE) Input: On your A/V receiver or processor’s Speaker
Setup Menu, set all speakers to “Small*” and set Subwoofer to “Yes” to direct all bass and LFE information to
the Sub(s).
Setting Channel Levels: Using your receiver or A/V processor’s Speaker Level Calibration Menu, set each speaker
(channel) in the system to the same volume level. While you can get reasonable results doing this by ear, it is best
to use an inexpensive Sound Pressure (SPL) meter to get better channel to channel balance. Some new receivers
and processors have Auto Set Up functions that use a supplied microphone to set levels automatically. Also note
that bass level should be set to individual taste, not just to a given reading on the SPL meter. Also note that most
inexpensive SPL meters suffer signifi cant roll-off when measuring bass frequencies, making it even more important
to “adjust bass to taste.”
NOTE: When using High-Level (speaker wire) connection, the subwoofer level will be set by the subwoofer’s level
control, not the bass management system of you’re a/v receiver or processor.
(*Small and Large settings on speaker setup menus determine the routing of bass information, see your dealer for
more assistance on the correct settings for your specifi c speaker system and environment.)
