OPERATION
Move the Master Power Switch
⁄
(marked Power ) to the “
•
” (On) position.
The SUB-TS10 subwoofer will automatically
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 to the
right so that it is in the
AUTO
position.
When your receiver or amplifier is off, or is
not sending program material to the sub-
woofer, the subwoofer will be in Standby
mode and the
LED Indicator
ª
on the
amp panel will turn red. When the sub-
woofer senses an audio signal, it will auto-
matically turn itself on and the
LED
Indicator
ª
will turn green. If the sub-
woofer does not sense a signal after
approximately twenty minutes, it will auto-
matically go into Standby mode.
When the Music-Sense On/Off Switch
¶
is switched to the
ON
position, the sub-
woofer will remain on, whether or not pro-
gram material is playing.
If you will be away from home for an
extended period of time, or if the sub-
woofer will not be used, switch the
Master
Power Switch
⁄
to the
OFF
position.
Volume
Volume can be adjusted using the
Subwoofer-Level Control
‚
, as shown
below.
Additional Bass Adjustments
In addition to the volume adjustments
described above, the SUB-TS10 subwoofer
includes a
Phase Switch
∞
and a Filter
Switch
§
that can be used to adjust the
bass response to suit your listening environ-
ment 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 sig-
nal inputted to the subwoofer to the low
frequencies 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
£
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
on board the receiver or processor. In these
two circumstances, place the switch in the
OFF
position.
