0 Subwoofer-Level Control: Volume
may be adjusted using the Subwoofer-Level
Control. Turn the control clockwise to increase
the SUB-TS7’s volume, or counterclockwise to
decrease it.
1 High-Cut (Low-Pass) Filter Switch: Plac-
ing this switch in the
O N position activates cir-
cuitry that cuts out all audio input signals above
120Hz. This allows the SUB-TS7 to focus its
power on reproducing the low-frequency portion
of the signal, avoiding inefficiency and distor-
tion. Engage this filter when using the Speaker-
Level Inputs
7, or when using the Line-
Level Full-Range Inputs 5, unless your
receiver or processor processes its line-level out-
put using a low-pass filter. The filter has no
effect when the Sub Input
4 is used.
2 Trigger Input: Some receivers or sound
processors have a Trigger Output that sends a
signal to the subwoofer to switch on or off. If
your receiver has such a Trigger Output, connect
it here. When placed in the
AUTO position, and
when the Master Power Switch 8 is turned
on, the subwoofer will automatically turn itself
on or place itself in the Standby mode,
depending on the status of your receiver or
processor.. When this switch is placed in the
O N
position, the SUB-TS7 will remain on, whether or
not it is receiving an audio signal.
An LED located on top of the SUB-TS7 indicates
whether the SUB-TS7 is in the On or standby
state when used with the Trigger On/Off
Switch
2 in the
AUTO position. The LED is lit
blue to indicate that the SUB-TS7 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-TS7 is in Standby mode.
When the Trigger On/Off Switch 2 is in the
O N position, the LED will be lit blue, whether or
not an audio signal is present.
When the Master Power Switch 8 is turned
off, the LED goes dark, no matter which position
the Trigger On/Off Switch
2 is in.
3 Phase Switch: This switch determines
whether the SUB-TS7 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 sub-
woofer 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
3
should be left in the NORMAL position. How-
ever, it does no harm to experiment with the
Phase Switch
3, and you may leave it in the
position that maximizes bass response.
