SUB-TS18 SUBWOOFER AMPLIFIER PANEL CONTROLS AND CONNECTIONS
SUB-TS18 SUBWOOFER AMPLIFIER PANEL CONTROLS AND CONNECTIONS
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-TS18 will remain on, whether or not it is
receiving an audio signal.
An LED located on top of the SUB-TS18
indicates whether the SUB-TS18 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-TS18 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-TS18 is in the 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-TS18 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 canceled
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-TS18’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 a Y-adapter (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 adapter
to the corresponding line-level input on the
SUB-TS18. 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-TS 18, and no Y-adapter is needed.
•
Speaker-Level Outputs:
If you are
using the
Speaker-Level Inputs
ª
on the
SUB-TS18, 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-TS18 subwoofer to the (+) terminal
on the speaker, and the (–) terminal on the
SUB-TS18 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 sub-
woofer 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-TS18 subwoofer, and
the (–) terminal on the receiver/amplifier to the
(–) terminal on the SUB-TS18 subwoofer.
‚
Master Power Switch:
Place this
switch in the “•” position to power-on the
SUB-TS18 subwoofer. The SUB-TS18 will
then be either in the Standby mode or com-
pletely 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 out-
let for proper operation of the SUB-TS18.
The cord should not be plugged into the
accessory outlets found on some audio
components.
