¡Subwoofer-Level Control: Volume
may be adjusted using the Subwoofer-
Level Control.Turn the control clockwise
to increase the SUB-TS14’s volume, or
counterclockwise to decrease it.
™High-Cut (Low-Pass) Filter Switch:
Placing this switch in the ON position acti-
vates circuitry that cuts out all audio input
signals above 120Hz.This allows the SUB-
TS14 to focus its power on reproducing the
low-frequency portion of the signal, avoiding
inefficiency and distortion. Engage this filter
when using the Speaker-Level Inputs •,
or when using the Line-Level Full-Range
Inputs §,unless your receiver or processor
processes its line-level output using a low-
pass filter.The filter has no effect when the
SUB Input ∞is used.
£Music-Sense On/Off Switch:When
placed in the AUTO position,and when the
Master Power Switch ªis turned on,the
SUB-TS14 will automatically turn itself on or
place itself in the Standby mode, depending on
whether it is receiving an audio signal.When
this switch is placed in the ON position,the
SUB-TS14 will remain on,whether or not it is
receiving an audio signal.
An LED located on top of the SUB-TS14
indicates whether the SUB-TS14 is in the
ON or STANDBY state when used with the
Music-Sense On/Off Switch £in the
AUTO position.The LED is lit blue to indi-
cate that the SUB-TS14 is receiving an

audio signal and is turned on, and the LED
is lit amber to indicate that no signal is being
received and the SUB-TS14 is in Standby
mode.
When the Music-Sense On/Off Switch £
is in the ON position, the LED will be lit
blue, whether or not an audio signal is
present.
When the Master Power Switch ªis
turned off, the LED goes dark,no matter
which position the Music-Sense On/Off
Switch £is in.
¢Phase Switch: This switch determines
whether the SUB-TS14 subwoofer’s piston-
like action moves in and out in phase with
the main speakers. If the speakers were to
play out of phase, the sound waves pro-
duced by the subwoofer would be cancelled
out, reducing bass response.This phenome-
non depends in part on the relative place-
ment of the speakers in the room. In most
cases, the Phase Switch ¢should be left
in the NORMAL position. However, it
does no harm to experiment with the Phase
Switch ¢,and you may leave it in the
position that maximizes bass response.
∞Line-Level Subwoofer (SUB) Input:
Connect the subwoofer output of a receiver
with digital surround sound decoding, such
as Dolby* Digital or DTS®
,to this input.This
input bypasses the SUB-TS14’s internal
crossover circuitry, and should only be used
with a filtered signal. If your receiver does not
have digital decoding,you should use the
Line-Level Full-Range Inputs §instead.
§Line-Level Full-Range Inputs: Connect
the line-level subwoofer output or preamp out-
put(s) of your receiver or amplifier to these
inputs. If your receiver does not have a sepa-
rate subwoofer output, use aY-adaptor (not
supplied) to bridge the receiver’s preamp out-
put to the main amp input for that channel,
and connect the long end of the adaptor
to the corresponding line-level input on the
SUB-TS14. If your receiver has only a single
subwoofer output, you may connect it to
either the left or right line-level input on the
SUB-TS14, and noY-adaptor is needed.
¶Speaker-Level Outputs: If you are
using the Speaker-Level Inputs •on the
SUB-TS14, you should connect these bind-
ing post terminals to your front left and right
speakers, remembering to maintain polarity
by connecting the (+) terminal on the SUB-
TS14 subwoofer to the (+) terminal on the
speaker, and the (–) terminal on the SUB-
TS14 subwoofer to the (–) terminal on the
speaker. If you are not using the Speaker-
Level Inputs •,then connect your front
left and right speakers directly to your receiv-
er or amplifier. See pages 9 through 12 for
further information on speaker connections.
•Speaker-Level Inputs: Connect these
binding-post terminals to the main left and
right speaker terminals of your receiver or
amplifier, if your receiver or amplifier does
not have a line-level subwoofer output.
Remember to maintain polarity by connecting
the (+) terminal on the receiver/amplifier to the
(+) terminal on the SUB-TS14 subwoofer, and
the (–) terminal on the receiver/amplifier to the
(–) terminal on the SUB-TS14 subwoofer.
ªMaster Power Switch: Place this
switch in the “•” position to power-on the
SUB-TS14 subwoofer.The SUB-TS14 will
then be either in the Standby mode or com-
pletely on, depending on the position of the
Music-Sense On/Off Switch £.
‚AC Power Cord: Make sure to plug this
cord into an active, unswitched electrical out-
let for proper operation of the SUB-TS14.
The cord should not be plugged into the
accessory outlets found on some audio
components.

OPERATION 13
OPERATION
Move the Master Power Switch ª
(marked Power) to the “•”(On) position.
The SUB-TS14 subwoofer will automatically
turn itself on or go into Standby mode,
depending on whether or not a signal is
being sent to it by your receiver or surround
processor, and provided that the Music-
Sense On/Off Switch £is moved down
so that it is in the AUTO position.
When your receiver or amplifier is off, or is
not sending program material to the sub-
woofer, the subwoofer will be in Standby
mode and the LED Indicator on the top
of the subwoofer will turn amber.When the
sub
woofer senses an audio signal,
it will auto-
matically turn itself on and the LED Indicator
will turn blue. If the subwoofer does not
sense a signal after
approximately twenty
minutes,
it will automatically go into Standby
mode.
When the Music-Sense On/Off Switch £
is switched to the ON position, the sub-
woofer will remain on, whether or not pro-
gram material is playing, and the LED
Indicator will remain lit blue.
If you’ll be away from home for an extended
period of time, or if the subwoofer will not be
used, switch the Master Power Switch ª
to the OFF position.
Volume
Volume can be adjusted using the Sub-
woofer-Level Control ¡,as shown.
Turn the control knob clockwise to
increase the volume of the subwoofer,
and counterclockwise to decrease the
subwoofer’s volume.
Additional Bass Adjustments
In addition to the volume adjustments
described above, the SUB-TS14 subwoofer
includes a Phase Switch ¢and a Filter
Switch ™that can be used to adjust the
bass response to suit your listening environ-
ment or taste.
In most situations, the Phase Switch ¢
should be left in the NORMAL position.
If you suspect that the subwoofer is playing
out of phase with the other speakers, which
would tend to diminish bass response, try
placing this switch in the REVERSE
position.There is no harm in experimenting,
and you may return the switch to the
NORMAL position at any time. If you
rearrange your room and reposition the
speakers, it would be a good idea to check
whether they are in phase by flipping this
switch.
The High-Cut (Low-Pass) Filter Switch
™limits the frequencies of the audio signal
inputted to the subwoofer to the low fre-
quencies that the subwoofer reproduces
best.This allows the subwoofer to perform
more efficiently, and with superior bass
reproduction, minimizing distortion that might
occur if the subwoofer attempted to repro-
duce higher frequencies.This switch should
be left in the ON position, except:
1.When the SUB Input ∞is being used,
in which case it has no effect, or
2.When the Speaker-Level Inputs •or
the Line-Level Full-Range Inputs §are
being used with a crossover or filter aboard
the receiver or processor.
In these two circumstances, place the switch
in the OFF position.
