CONNECTIONS AND CONTROLS
CAUTION: Ensure that the subwoofer is unplugged from the AC wall outlet
before making any connections.
“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 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 alternative 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.
WA-2 Port Connection - For wireless connectivity of your new Klipsch
R-110SW, R-112SW, or R-115SW subwoofer, the optional WA-2 is available. The
WA-2 will only operate with select Klipsch, Energy, Mirage and Jamo brand
subwoofers that have a “WA Port” input. The WA-2 is a 2.4 GHz product
designed to wirelessly transmit a signal up to a 50 foot radius. See klipsch.
com for more details.
Level - 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 volume (or gain) of the
subwoofer up 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 speakers together. If your subwoofer is connected to the
L/R Pre-Amp Outputs of a receiver there will be no subwoofer volume in that
receiver to set before setting the subwoofer’s gain control.
“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 (160Hz). 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 recommended 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 the position, either 0° or 180°, in which
your subwoofer has more output at the listening position.
“POWER” AUTO/ON/OFF -
When this switch is in the “ON/AUTO/STANDBY”
position, the subwoofer will automatically turn “on” when it senses a signal. It
will automatically go into “standby mode” after 15-20 minutes with no signal.
When this switch is in the “OFF” position, the subwoofer will remain “off” until
the switch is manually turned back to the “ON/AUTO/STANDBY” position.
Power LED indicator - Located on the front baffle, this LED indicates the
operating status of the built-in amplifier. The LED will light 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
