SUB-TS15 SUBWOOFER AMPLIFIER PANEL CONTROLS AND CONNECTIONS

¡ Subwoofer-Level Control: Volume
may be adjusted using the Subwoofer-
Level Control. Turn the control clockwise
to increase the SUB-TS15’s volume, or
counterclockwise to decrease it.

™ High-Cut (Low-Pass) Filter Switch:

Placing this switch in the ON position acti­vates circuitry that cuts out all audio input
signals above 120Hz. This allows the SUB­TS15 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 ª,
or when using the Line-Level Full-Range
Inputs ¶, unless your receiver or processor
processes its line-level output using a low­pass filter. The filter has no effect when the

SUB Input § is used.

£ External Trigger Input: Use the sup-

plied mini-plug cable to connect the trigger
output of another compatible product to this
jack. Whenever a trigger signal between

3 and 30 volts (AC or DC) is detected, the
SUB-TS15 amplifier will turn on, even when
the Audio-Sense feature has been activated
by placing the Audio-Sense On/Off Switch
¢ in the AUTO position. The amplifier will
remain on for about 10–15 minutes without
a trigger signal.

¢ Audio-Sense On/Off Switch: When
placed in the AUTO position, and when the
Master Power Switch ‚ is turned on, the
SUB-TS15 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-TS15 will remain on, whether or not it is
receiving an audio signal.

An LED located on top of the SUB-TS15
indicates whether the SUB-TS15 is in the
ON or STANDBY state when used with the
Audio-Sense On/Off Switch ¢ in the
AUTO position. The LED is lit blue to indi­cate that the SUB-TS15 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-TS15 is in
Standby mode.

When the Audio-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 ‚ is
turned off, the LED goes dark, no matter
which position the Audio-Sense On/Off

Switch ¢ is in.

∞ Phase Switch: This switch determines

whether the SUB-TS15 subwoofer’s piston­like action moves in and out in phase with
the main speakers. If the speakers were to
play out of phase, the sound waves pro­duced by the subwoofer would be cancelled
out, reducing bass response. This phenome­non depends in part on the relative place­ment 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-TS15’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 out­put(s) of your receiver or amplifier to these
inputs. If your receiver does not have a sepa­rate subwoofer output, use a Y-adapter (not
supplied) to bridge the receiver’s preamp out­put to the main amp input for that channel,
and connect the long end of the adapter
to the corresponding line-level input on the
SUB-TS15. 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-TS15, and no Y-adapter is needed.

• Speaker-Level Outputs: If you are
using the Speaker-Level Inputs ª on the
SUB-TS15, you should connect these bind­ing-post terminals to your front left and right
speakers, remembering to maintain polarity
by connecting the (+) terminal on the SUB­TS15 subwoofer to the (+) terminal on the
speaker, and the (–) terminal on the SUB­TS15 subwoofer to the (–) terminal on the
speaker. If you are not using the Speaker-
Level Inputs ª, then connect your front
left and right speakers directly to your receiver
or amplifier. See pages 9 through 12 for
further information on speaker connections.

ª Speaker-Level Inputs: If your receiver
or amplifier does not have a line-level sub­woofer output, connect these binding-post
terminals to the main left and right speaker
terminals of your receiver or amplifier.
Remember to maintain polarity by connecting
the (+) terminal on the receiver/amplifier to the
(+) terminal on the SUB-TS15 subwoofer, and
the (–) terminal on the receiver/amplifier to the
(–) terminal on the SUB-TS15 subwoofer.

‚ Master Power Switch: Place this
switch in the “•” position to power-on the
SUB-TS15 subwoofer. The SUB-TS15 will
then be either in the Standby mode or com­pletely on, depending on the position of the

Audio-Sense On/Off Switch ¢.

⁄ AC Power Cord: Make sure to plug this

cord into an active, unswitched electrical out­let for proper operation of the SUB-TS15.
The cord should not be plugged into the
accessory outlets found on some audio
components.

Dolby®Digital or DTS®(or Other
Digital Surround Mode) Connection

USE THIS INSTALLATION METHOD FOR
DOLBY DIGITAL, DTS OR OTHER DIGITAL
SURROUND PROCESSORS:

Use the line-level input jack marked SUB

§ for the Low-Frequency Effects channel.
Connect this jack to the subwoofer output
or LFE output on your receiver or amplifier.
Connect each speaker to the corresponding
speaker terminals on your receiver or
amplifier.

Make sure you’ve configured your surround
sound processor for “Subwoofer On.” The
front left, front right, center and surround
speakers should all be set to “Small.”

When all connections have been made, plug
the AC power cord on the subwoofer into
an AC outlet.

USE THIS INSTALLATION METHOD FOR
DOLBY PRO LOGIC APPLICATIONS (NOT
DOLBY DIGITAL, DTS OR OTHER DIGITAL
PROCESSING), WHERE THE RECEIVER/
PROCESSOR IS EQUIPPED WITH A SUB­WOOFER OUTPUT, OR A VOLUME­CONTROLLED PREAMP (LINE-) LEVEL
OUTPUT:

Use the supplied RCA-type interconnect
cable to connect the

line-level subwoofer

output on your receiver

or amplifier to either

the left or right Line-Level Full-Range
Input ¶ on the SUB-TS15 subwoofer.
Use both the left and right inputs on the
subwoofer if your receiver or processor has
both left and right line-level outputs. In that
case, you will need to supply a second
interconnect cable.

If your receiver is equipped with line-level out­puts but does not have a separate subwoofer
output, use a Y-adapter (not supplied) to
bridge the receiver’s preamp output to the
main amp input for that channel, and connect
the long end of the adapter to the corre­sponding line-level input on the SUB-TS15.

IMPORTANT: Do not use the SUB Input

§ on the subwoofer with Dolby Pro Logic
processors.

If your receiver/processor has a built-in low­pass-crossover filter for the subwoofer out­put, you may use the SUB Input § to
bypass the subwoofer’s internal crossover.

Connect each speaker to the corresponding
speaker terminals on your receiver or amplifier.

Make sure that you have configured your
surround sound processor for “Subwoofer
On.” The front left, front right, center and
surround speakers should all be set to
“Small.”

When all connections have been made, plug
the AC power cord on the subwoofer into
