A Few Suggestions
We recommend that you do not operate your speakers or
subwoofer with the bass,treble and loudness controls set to
full boost.This will place undue strain on your electronics and
speakers and could damage them.
The volume control setting on your processor/preamp or receiver
is not a specific indication of the overall loudness level of the
speakers.The only important consideration is the loudness level at
which the system can be played, regardless of where the volume
control is set.
Always turn down the volume control setting on your processor/
preamp or receiver when changing sources,or switching inputs to
AM or FM operation. Excessively loud transients (clicks or popping
sounds) can damage the satellite speakers and possibly the
subwoofer.
Important!
Whenever changing cables, pulling plugs, etc.,ALWAYS TURN OFF
ALL EQUIPMENT, including the subwoofer.

OPERATION
Surround Modes
When using the TSS-800 in a Dolby Digital or DTS home theater
system, make sure all speakers are set to “Small”. In a Dolby
Pro Logic
center channel mode is set to “Normal.”
Some Dolby Digital-equipped receivers/processors offer different
setup options for each source or surround mode (e.g., CD-stereo,
videotape,Dolby, Pro Logic). In each case, follow your equipment’s
instructions to ensure that the subwoofer output is turned on and
that the speakers are set to “Small”in each mode.
Power On
Plug your subwoofer’s AC cord into a wall outlet.Do not use the
outlets on the back of the receiver.
Initially set the Subwoofer Level Control
Turn on the subwoofer by pressing the Power Switch
rear panel.
Turn on your entire audio system and start a CD or movie sound-
track at a moderate level.
Auto On/Standby
With the Power Switch 7in the ON position, the LED on the rear
panel
STANDBY mode of the subwoofer.
RED = STANDBY (No signal detected,Amp Off)
GREEN = ON (Signal detected,Amp On)
The subwoofer will automatically enter the Standby mode after
approximately 10 minutes when no signal is detected from your
system.The subwoofer will then power on instantly when a signal
is detected. During periods of normal use,the Power Switch
can be left on.You may turn off the Power Switch 7for extended
periods of nonoperation,e.g.,when you are away on vacation.

Crossover Adjustment
The Crossover Frequency Control 2 determines the highest
frequency at which the subwoofer reproduces sounds.For the
TSS-800,it is recommended that this control be set at 120Hz
(approximately the 3 o’clock position).
NOTE: This control will have no effect if the LFE Input 4 is
used. If you have a Dolby Digital or DTS receiver/processor,
the low-pass frequency is set by the receiver/processor.Consult
your owner’s manual to learn how to view or change this setting.
A setting of 120Hz – 150Hz is recommended.
Phase Control
The Phase Switch 3 determines whether the subwoofer
speaker’s pistonlike action moves in and out with the main
speakers (0˚) or opposite the main speakers (180˚). Proper
phase adjustment depends on several variables such as room
size,subwoofer placement and listener position. Adjust the phase
switch to maximize bass output at the listening position.
Final Positioning
After correctly connecting the TSS-800 system and verifying that
both the subwoofer and all satellite speakers are playing, it is
time to optimize the system for your particular listening room.
Earlier, you placed the subwoofer in its general location.Finding
the exact location for optimum performance sometimes only
involves moving the speakers up to a few inches in any
direction.We urge you, therefore, to experiment with placement,
if possible, until your speakers deliver their full potential.
MAINTENANCE AND SERVICE
The satellite and subwoofer enclosures may be cleaned using a
soft cloth to remove fingerprints or to wipe off dust.
Adjust Level
Turn the Subwoofer Level Control 1up about halfway.If no
sound emanates from the subwoofer, check the AC-line cord and
input cables.Are the connectors on the cables making proper
contact? Is the AC plug connected to a “live”receptacle? Has the
Power Switch
confirmed that the subwoofer is active, proceed by playing a CD
or DVD. Use a selection that has ample bass information.
Set the overall volume control of the receiver/processor to a
comfortable level.Adjust the Subwoofer Level Control
you obtain a pleasing blend of bass. Bass response should
not overpower the room but rather be adjusted so there is
a harmonious blend across the entire musical range. Many
users have a tendency to set the subwoofer volume too loud,
adhering to the belief that a subwoofer is there to produce lots of
bass.This is not entirely true.A subwoofer is there to enhance
bass, extending the response of the entire system so the bass
can be felt as well as heard.However,overall balance must
be maintained or the music will not sound natural.An experienced
listener will set the volume of the subwoofer so its impact on
bass response is always there but never obtrusive.

All wiring connections should be inspected and cleaned or
remade periodically.The frequency of maintenance depends on
the metals involved in the connections, atmospheric conditions
and other factors,but once per year is the minimum.
