SUB-TS10 SUBWOOFER AMPLIFIER PANEL CONTROLS AND 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-TS10 subwoofer,
and the (–) terminal on the receiver/amplifier to
the (–) terminal on the SUB-TS10 subwoofer.

™ Speaker-Level Outputs: If you are
using the Speaker-Level Inputs ¡ on
the SUB-TS10, you should connect these
binding post terminals to your front left and
right speakers,remembering to maintain
polarity by connecting the (+) terminal on

the SUB-TS10 subwoofer to the (+) termi­nal on the speaker,and the (–) terminal on
the SUB-TS10 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 receiver or amplifier. See pages 6 and
7 for further information.

£ 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-TS10’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: Con-

nect 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-adaptor
(not supplied) to bridge the receiver’s preamp
output 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-TS10. 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-TS10, and no Y-adaptor is needed.

whether the SUB-TS10 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 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.

§ 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 SUB­TS10 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 ⁄ is turned on,the
SUB-TS10 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 posi-
tion,the SUB-TS10 will remain on, whether or
not it is receiving an audio signal.

• Filter Remote Control Input: This
input accepts a remote control signal from
a compatible Harman Kardon A/V receiver
that enables you to override the High-Cut

(Low-Pass) Filter Switch

§, by signal­ing the SUB-TS10 to engage the filter even
when the switch is in the OFF position.

ª LED Indicator:This LED indicates
whether the SUB-TS10 is in the ON or
STANDBY state when used with the
Music-Sense On/Off Switch ¶ in the
AUTO position. The LED is lit Green to
indicate that the SUB-TS10 is receiving
an audio signal and is turned on, and the
LED is lit Red to indicate that no signal is
being received and the SUB-TS10 is in
Standby mode.

When the Music-Sense On/Off Switch
¶ is in the ON position, the LED will be lit
Green, 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

Music-Sense On/Off

Switch

¶ is in.

‚ Subwoofer-Level Control: Volume

can be adjusted using the

Subwoofer-

Level Control

.Turn the control clockwise
to increase the SUB-TS10’s volume, or
counterclockwise to decrease it.

⁄ Master Power Switch: Place this
switch in the “•”position to power-on the
SUB-TS10 subwoofer.The SUB-TS10 will
then be either in the Standby mode or
completely 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 outlet for proper operation of the SUB­TS10.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 that you have configured your
surround sound processor for “Subwoofer
On.” The front left,front right, center and
rear 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 patch cord 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-TS10 subwoofer. Use both the left
and right inputs on the subwoofer if your
receiver or processor has both left and right
line-level outputs.

If your receiver is equipped with line-level
outputs but does not have a separate sub­woofer output, use a Y-adaptor (not supplied)
to bridge the receiver’s preamp output 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-TS10.

IMPORTANT:Do not use the SUB Input £
on the subwoofer with Dolby Pro Logic
processors.Make sure that you have config­ured your surround sound processor for
“Subwoofer On.” The front left,front right,
center and rear 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.

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