Placing the Soundbar and Subwoofer
and Connecting the System
5. After making all of the connections described in Connecting the System, on this
page, attach the soundbar to the brackets by sliding the slots in its feet onto the
brackets’ vertical tabs.
Placing the Subwoofer
The performance of a subwoofer is directly related to its placement in the listening room
and its physical position relative to the other speakers in the system.
While it is true that in general our ears do not hear directional sounds at the low
frequencies where subwoofers operate, when installing a subwoofer within the limited
conﬁnes of a room, the reﬂections, standing waves and absorptions generated within the
room will strongly inﬂuence the performance of any subwoofer system. As a result, the
speciﬁc location of the subwoofer in the room does become important to the amount and
quality of bass that is produced.
For example, placing the subwoofer next to a wall generally will increase the amount of
bass in the room; placing it in a corner (1) generally will maximize amount of bass in the
room. However, corner placement can also increase the destructive effect of standing
waves on bass performance. This effect can vary depending on the listening position –
some listening positions may yield very good results while others may have far too much
(or too little) bass at certain frequencies.
In many rooms, placing the subwoofer along a wall away from a corner (2) can produce
the best integration between the sound of the subwoofer and that of the left and right
speakers. In some rooms, the best performance could even result from placing the
subwoofer behind the listening position (3).

We strongly recommend that you experiment with placement before choosing a ﬁnal
location for your subwoofer. One way you can determine the best location for the
subwoofer is by temporarily placing it in the listening position and playing music with
strong bass content. Move around to various locations in the room while the system is
playing (putting your ears where the subwoofer would be placed), and listen until you ﬁnd
the location where the bass performance is best. Place the subwoofer in that location.
Connecting the System
Analog: Use the supplied stereo audio cable to connect the soundbar’s Analog Input
connectors to your TV’s stereo audio output. If your TV has two sets of audio output
jacks, use the set that has a ﬁxed (not variable) output level. It will let you turn your
TV’s speakers all the way off while the TV still supplies a constant audio signal to the
Digital: If your disc player, cable tuner or satellite tuner has a coaxial or optical digital
output, you can use the supplied optical digital audio cable and a coaxial digital audio
cable (not supplied) to connect them to the soundbar’s Optical and Coaxial Digital Input
connectors. We recommend setting the component’s digital output to “Bitstream” so it
will send Dolby
Digital and DTS
bitstreams to the SB 30 CNTR for decoding. This will
produce better results when using the Virtual and HARMAN Wave surround modes (see
Surround Modes, on page 11).
NOTE: If your disc player, cable tuner or satellite tuner does not have a digital output you
can connect its analog audio output to your TV. The TV will send its audio signal to the
soundbar through the analog connection described above.

Voltage Selector Switch
The soundbar’s Voltage Selector switch is set at the factory to accommodate the AC
power voltage in the area where the soundbar is shipped.
IMPORTANT: Before you connect the power cord for the ﬁrst time it is a good idea
to verify that the setting of the voltage selector is appropriate for the power in
In the event that you do need to change the Voltage Selector switch setting:
6. Make sure that the soundbar is powered off and the power cord is disconnected
from the soundbar.
7. Slide the Voltage Selector switch to the appropriate setting (“110 – 120V” or “220 –
240V”) as required for your area.
WARNING: DO NOT UNDER ANY CIRCUMSTANCES OPERATE THE SOUNDBAR WITH
THE WRONG VOLTAGE SELECTED. DOING SO MAY RESULT IN SERIOUS DAMAGE TO
THE SOUNDBAR, WHICH WILL NOT BE COVERED BY WARRANTY.
