DUAL SUBWOOFER CONNECTIONS
Connection using Left/LFE Inputs – From your A/V 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 analog interconnect
cable to each subwoofer’s LEFT/LFE Input. Select the LFE In (DOWN) position on the Input Select switch. For further
setup instructions, refer to Bass Management System Setup section below.
Connection using Left/Right Inputs – Connect the Left preamp output to the Left RCA input of the first sub and the
Right preamp output to the Right RCA input on the second sub. Select the Left/Right In (UP) position of the Input
Switch.
BASS MANAGEMENT SETUP FOR MULTI-CHANNEL, 5.1-CHANNEL, 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 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 significant roll-off when measuring bass frequencies, making it even more important
to “adjust bass to taste.”
(*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 specific speaker system and environment.)
