SPEAKER CONNECTIONS 9

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 LFE output or subwoofer 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 sur-
round-sound processor for “Subwoofer On.”
The front left, front right, center and rear speak-
ers should all be set to “Small.”

10 SPEAKER CONNECTIONS

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
volume-controlled preamp (line-) level output:

Use RCA-type patch cords to connect the line-
level subwoofer output on your receiver or to
amplifier either the left or right line-level input
on the subwoofer.

Use both the left and right inputs on the sub-
woofer 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 out-
puts 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-TS.

IMPORTANT: Do not use the Sub Input

 on

the subwoofer with Dolby Pro Logic processors.

If your receiver/processor has a built-in low-
pass-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 sur-
round 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.

SPEAKER CONNECTIONS 11

Use this installation method for Dolby Pro Logic
applications (not Dolby Digital, DTS

®

or other

digital processing), where the receiver/processor
does not have a subwoofer output, or a volume-
controlled preamp (line-) level output:

Connect your receiver or amplifier’s front left
and right speaker terminals to the left and right
terminals on the subwoofer that are marked
“High Level In.”

Connect the left and right terminals on the sub-
woofer that are marked “High Level Out” to the
corresponding terminals on the back of your
front left and right speakers.

Connect your receiver or amplifier’s center, left
and right surround-speaker terminals to the
corresponding terminals on the back of your
center, left and right surround speakers.

12 OPERATION

Move the Master Power switch (marked
“Power”

) to the “•” (On) position to use the

subwoofer. The SUB-TS subwoofer will automati-
cally 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 ampli-

fier is off, or is not sending program material to
the subwoofer, the subwoofer will be in standby
mode and the LED Indicator on the top of the
subwoofer will turn amber. When the subwoofer
senses an audio signal, it will automatically turn
itself on and the LED Indicator will turn blue.
If the subwoofer does not sense a signal after
approximately twenty minutes, it will automati-
cally go into standby mode.

When the Music Sense switch

 is switched

to the “On” position, the subwoofer will remain
on, whether or not program material is playing
and the LED Indicator will remain lit blue.

If you will be away from home for an extended
period of time, or if the subwoofer will not be
used, switch the Master Power switch

 to

the 

OFF

position.

Volume can be adjusted using the Subwoofer
Level Control 

 (above), as shown below.

Turn the control knob clockwise to increase the
volume of the subwoofer, and counterclockwise
to decrease the subwoofer's volume.

In addition to the volume adjustments described
above, the SUB-TS subwoofer includes a Phase
Switch

 and a Filter Switch  that can be

used to adjust the bass response to suit your lis-
tening environment 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 frequen-
cies 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 reproduce higher
frequencies. This switch should be left in the 

O N

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

 are being

used with a crossover or filter aboard the
receiver or processor.

In these two circumstances, place the switch in
the 

OFF

position.
