literature accompanying the prodUCt.
POSITIONING YOUR SW SUBWOOFER
Klipsch powered subwoofers are designed to reproduce deep bass and deliver
the impact that makes your movies and music come alive. Typically, optimum
performance 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 placement can have a dramatic effect upon the performance of your pow-
ered 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 decrease 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.
CONNECTIONS AND CONTROLS
CAUTION: Turn off your amplifier and your subwoofer before making any connec-
tions. Do not connect both "High Level" and "Line Level" inputs at the same time
as damage to your equipment could result!
"LINE IN" Connection - Most of today's surround receivers (and pre-amplifiers)
have 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 connec-
tion 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 alternative hookup, you can connect Left and Right channel Pre-Amp Outputs
from your receiver Of provided) to the LefVLFE and Right input on the subwoofer.
WARNING: No naked flame sources - such as candles - should be placed on the product.
WARNING: To reduce the risk of fire or electrical shock, do not expose this apparatus to rain or moisture.
The lightning flash with arrowhead symbol within an equilateral triangle, is intended
to alert the user to the presence of uninsulated "dangerous voltage" within the
product's enclosure that may be of sufficient magnitude to constitute a risk of
electrical shock to persons.
"GAIN" Control - If your subwoofer is connected to a Subwoofer Output of a
surround receiver, first set the subwoofer volume level control in the receiver to
the "half way" or "0 dB" position. Then increase the gain of the subwoofer until
the subwoofer's volume level matches the output of your main speakers. After
this setup is completed, the volume control on your system's main amplifier or
pre-amplifier will be the volume control for both your subwoofer and speak-
ers together. If your subwoofer is connected to the UR Pre-Amp Outputs of a
receiver or connected via the High-Level connection to the receiver's speaker
terminals, there will be no subwoofer volume in that receiver to set before setting
the subwoofer's gain control.
A
WARNING: Do Not Open I Risk of Electrical Shock. Voltages in this
equipment are hazardous to life. No user-serviceable parts inside.
Refer all servicing to qualified service personnel.
WARNING: This product is intended to be operated ONLY from the AC Voltages listed on the back
panel or included power supply of the product. Operation from other voltages other than those
indicated may cause irreversible damage to the product and void the products warranty. The use
of AC Plug Adapters is cautioned because it can allow the product to be plugged into voltages
in which the product was not designed to operate. If the product is equipped with a detachable
power cord, use only the type provided with your product or by your local distributor and/or
retailer. If you are unsure of the correct operational voltage, please contact your local distributor
and/or retailer.
INSPECTION
We want your new speaker system to look as good as it did leaving the fac-
tory! Please check promptly for 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 service 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.
"LOWPASS" Control - The crossover point chosen determines where low bass
frequencies are "handed off" from the speakers to the subwoofer. If setting the
crossover point in the receiver, turn the Lowpass Filter knob on the subwoofer
to the farthest point right (150Hz). Set the crossover point based on the size of
the main left/right speakers you are using in the system. As a general rule, for
larger, floorstanding speakers, set the crossover point between 50hz-90Hz. If
using small bookshelf or "satellite" speakers for the mains, set the crossover point
between 90Hz-150Hz. The smaller the speaker, the higher the setting until the
bass frequencies blend well between the speakers and your subwoofer once your
system is completely hooked up. If your receiver does not have a crossover point
setting, set the Lowpass Filter on the subwoofer instead within the same recom-
mended settings. (See receiver manual for additional speaker setup info)
"PHASE" 0/180 - This control is used to acoustically match the subwoofer's
output to your main speakers. Select a position, between 0° and 180°, in which
your subwoofer has more output at the listening position.
"POWER" AUTO/ON/OFF - This is the main AlC power switch for the subwoofer.
This switch must be in the "ON" position for the subwoofer to operate and for
the "AUTO/ON" switch to function. Set this switch to the "OFF" position if the
subwoofer will not be used for an extended period of time (i.e. vacation).

When this switch is in the "AUTO" position, the subwoofer will automatically turn
"on" when it senses a signal. It will automatically turn "off" after 20 minutes with
no signal. When this switch is in the "ON" position, the subwoofer will remain "on"
as long as the "POWER" ON/OFF switch is in the "ON" position. When this switch
is in the "OFF" position, the subwoofer will remain "off" as long as the "POWER"
ON/OFF switch is in the "OFF" position.
Power LED indicator - Located on the front baffle, this LED indicates the oper-
ating status of the built-in amplifier. The LED will light red when the amplifier is
in standby mode and green when the amplifier is on and receiving a signal. If the
LED is dark and not lit, the amplifier is off. For more information on the controls
mentioned in this manual and on bass management, see your dealer or visit
www.klipsch.com.
CARE AND CLEANING OFYOUR POWERED SUBWOOFER
Your subwoofer has a durable vinyl finish that should only require dry dusting or
cleaning with a dry cloth. Avoid the use of abrasive or solvent-based cleaners and
harsh detergents. The brush attachment of your vacuum should remove any dust
from your subwoofer enclosure.
