INSPECTION
We want your new speaker system to look as good as it did leaving the fac-
tory! Please check promptly f or any transit damage. Carefully unpack your new
speaker system and verify the components against the packing list. In extreme
circumstances, items may have become damaged in transit. If any damage is dis-
covered, notify the delivery ser vice and dealer where the system was purchased.
Make a request for inspection, and follow their instructions for evaluation. Be sure
to keep the product’ s original shipping carton.
POSITIONING YOUR SW SUBW OOFER
Klipsch powered subwoofers are designed to reproduce deep bass and deliver the
impact that makes your movies and music come alive. T ypically , optimum perfor-
mance will result if you place your subwoofer in a corner of the room on the same
wall as your front channel speakers (Refer to Figure 1). Please note that room place-
ment can have a dramatic effect upon the performance of your powered subwoofer .
Corner placement, as suggested above, will increase the amount of bass output,
while placing the subwoofer along the middle of a wall, or out in the room will de-
crease the amount of bass output. Experiment with a number of different placement
options and control settings to find the one that best suits your particular room and
taste. When choosing your subwoofer’ s location, keep in mind that you will need to
connect the subwoofer’ s built-in amplifier to an AC power outlet.
The SW-311 powered subwoofer features “Ada ptive Room Correction™”
This Klipsch patented technology (US Patent 7,529,377) will identify the major
acoustic anomalies in the low frequency range of your listening room’ s acoustics
and compensate for them automatically . While the corrected response may a t first
sound like a reduction in bass quantity , the benefit is a much higher quality bass
reproduction featuring audibly faster transient response and more noticeable ex-
tension of extremely low frequency program material. (See the “Room Correction”
section of this manual).
CONNECTIONS
CAUTION: Ensure that the subwoofer is unplugged from the AC wall outlet before
making any connections.
“LINE IN” - Most of today’ s surround receivers (and pre-amplifiers) ha ve a line level
subwoofer output labeled Subwoofer Pre Out, Sub Out, SW Out, etc. If you have
this output, connect one end of a subwoofer cable to it and connect the other end
of the cable into the subwoofer line input labeled LEFT/LFE. This connection allows
the subwoofer to operate with both music and surround sound movies (refer to your
receiver manual). In absence of a subwoofer output on your receiver , as an alterna-
tive hookup, you can connect Left and Right channel Pre-Amp Outputs from your
receiver (if provided) to the Left/LFE and Right input on the subwoofer .
“LINE OUT” - This jack can be used as an alternate method of connecting a
second subwoofer to your system. Use high quality , shielded cables for these
connections.
CONTR OLS
All of the subwoofer’ s controls, and changes to control settings, are accessed
through the key pad and display on the top of the subwoofer’ s cabinet.
• Use the (UP) or (Down) key to scroll through the list of control options.
• Use the (Left) or (Right) Key to make adjustments to a given control setting
• Use (Enter Key) when the appears on the display to store and recall
custom settings or to lock the keypad
