OPERATION
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
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.
Additional Bass Adjustments
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
Line-Level Full-Range Inputs
are being
used with a crossover or filter aboard the
receiver or processor.
In these two circumstances, place the switch in
the
OFF
position.
