12 OPERATION
Operation
Move the Master Power switch (marked
“Power”
8
) to the “•” (On) position to use the
subwoofer.The SUB-TS11 subwoofer will auto-
matically 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
2
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
2
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
8
to
the
OFF
position.
Volume
Volume can be adjusted using the Subwoofer
Level Control
0
(above), as shown below.
Turn the control knob clockwise to increase the
volume of the subwoofer, and counterclockwise
to decrease the subwoofer's volume.
Additional Bass Adjustments
In addition to the volume adjustments described
above, the SUB-TS11 subwoofer includes a
Phase Switch
3
and a Filter Switch
1
that
can be used to adjust the bass response to suit
your listening environment or taste.
In most situations, the Phase Switch
3
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
1
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
ON
position, except:
1.When the Sub Input
4
is being used, in
which case it has no effect, or
2.When the Speaker-Level Inputs
7
or the
Line-Level Full-Range Inputs
5
are being
used with a crossover or filter aboard the
receiver or processor.
In these two circumstances, place the switch in
the
OFF
position.
