SUB-TS12 SUBWOOFER AMPLIFIER PANEL CONTROLS AND CONNECTIONS
SUB-TS12 SUBWOOFER AMPLIFIER PANEL CONTROLS AND CONNECTIONS
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.
§
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-
TS12 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-TS12 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-TS12 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-TS12 to engage the fil-
ter even when the switch is in the
OFF
position.
ª
LED Indicator:
This LED indicates
whether the SUB-TS12 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-TS12 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-TS12 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-TS12’s volume, or
counterclockwise to decrease it.
⁄
Master Power Switch:
Place this
switch in the “•” position to power-on the
SUB-TS12 subwoofer. The SUB-TS12 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-TS12.
The cord should not be plugged into the
accessory outlets found on some audio
components.
