PLACEMENT
Although your Reference Series subwoofer will perform well in a wide variety of locations,you
will get the most out of it by following some simple guidelines:
Although the subwoofer's orientation is not critical, avoid placing the front (driver) side of the
•
cabinet up against a wall.
The subwoofer's output will increase as it is moved closer to walls,with maximum output
•
achieved when it is placed in a corner. If practical,always place the subwoofer against or
near a wall.
In most rooms,a subwoofer will deliver smoothest bass response when placed in a corner
•
away from room openings,such as doors.
If you are using more than one subwoofer, you will usually achieve the best performance by
•
placing them together in the same area rather than by spacing them apart.
CONNECTION AND ADJUSTMENT
Make all connections with the power turned off on your subwoofer and main amplifier. Your
subwoofer has three sets of input connections on its back panel:(1) a single LFE-Direct RCA
jack that bypasses the internal crossover; (2) a pair of RCA jacks for line-level stereo (or mono)
input; and (3) a set of terminals for connection to speaker outputs on a receiver or amplifier. In
addition,there are four controls on the back panel:(1) Main Power; (2) Auto Power On/Off;
(3) Phase; and (4) Lowpass Crossover Frequency . The Volume Level control is located on the
upper right side panel of the subwoofer.
Digital Surround Receiver or Processor
Connection — Today's Dolby Digital ® (AC-3) and DTS
processors have line-level subwoofer outputs and built-in subwoofer crossovers.If your system
is built around one of these,it will almost always be best to connect the subwoofer output on
the receiver or processor to the subwoofer's LFE Direct input (See Figure 1).This will bypass
the subwoofer's internal crossover and should only be done if these can be managed internally
in the receiver. Use a shielded,high quality subwoofer interconnect cable of appropriate length
with RCA plugs on each end. Your dealer can help you select a suitable cable.Be sure to go
into your receiver or processor's speaker setup menu and set Subwoofer to "On" or "Yes."
Your receiver or processor may have additional bass management abilities beyond simply
activating the subwoofer output.Consult your receiver or processor's owner's manual or your
dealer for more information on the proper bass management settings for your system.
Figure 1
Power — Set the subwoofer's Main Power switch to "Off." Then plug the power cord into an
AC outlet. You can turn the power on and off manually using the switch,or you can leave the
Main Power turned on and set the Auto Power switch to "On," which will automatically turn the
subwoofer on when a signal is detected at one of the inputs and off after a period of inactivity.
We recommend Auto Power "On" for most systems.
