one.Speaker Placement
Satellites
The customer is responsible for
proper selection and use of
mounting hardware, available
through hardware stores, to
properly and safely wall-mount
the speakers.
Always start with the subwoofer
as close to one of the front cor-
ners as possible to take advan-
tage of solid-angle gains. If you
get too much bass, adjust the
”VOLUME” towards ”MIN”. The
result will be lower distortion
and higher reliability. If the
excessive bass is at one or more
discrete frequencies, then it
might be necessary to consider
dealing with room modes.
Here are your options:
• Modify the acoustical coupl-
ing of the subwoofer to the
room boundaries and/or the
room modes, i.e. move the
subwoofer.
• Modify the acoustical cou-
pling of the listener to the
room boundaries and/or the
room modes, i.e. move the
listener.
• Move both the subwoofer and
the listener.

two.Speaker Connections
Separate and strip the ends of
the speaker wire as shown.
Speakers and amplifiers/-
receivers have corresponding
(+) and (–) terminals. The (+)
lead of the speaker wire is
noted with a stripe. It is impor-
tant to connect all the speakers
identically: (+) on the speaker
to (+) on the amplifier and (–)
on the speaker to (–) on the
amplifier. Wiring “out of phase”
results in thin sound, weak bass
and a poor stereo image.

Volume
If your receiver has subwoofer
output jacks, you may connect
the SCS175 using this method.
Note: Some receivers/
amplifiers have a single
(mono) subwoofer output. In
this case, it is recommended
that you use a “Y”-connector
(not included) to maximize the
subwoofer’s performance.
Crossover Frequency
The crossover frequency knob
determines the highest frequen-
cy your subwoofer will reprodu-
ce. It allows a seamless transi-
tion from the subwoofer to the
satellite speakers. Experiment
with this adjustment to find
the crossover frequency that
sounds best with your speakers.
When the control is at the
”40Hz“ position, very few
high frequencies will be heard.
This position is best suited to
large main speakers. For most
users, the control should be
set somewhere near the mid
position. For listeners using
very small speakers, best
results will be obtained with
the control at the ”130 Hz“
position.
For subwoofers used with
Surround Sound processors
with dedicated subwoofer out-
puts, the best result will be
obtained with the control at
the ”130 Hz“ position.

If there is no sound from any
of the speakers, check the
following:
• Receiver/amplifier is on and a
source is playing.
• Powered subwoofer is plugged
in and is in the “On” position.
• Check all wires and con-
nections between receiver/
amplifier and speakers. Make
sure all wires are connected.
Make sure none of the speaker
wires are frayed, cut or
punctured.
• Review proper operation of
your receiver/amplifier.
If there is no sound coming
from one speaker, check the
following:
• Check the “Balance” control
on your receiver/amplifier.
• Check all wires and con-
nections between receiver/
amplifier and speakers. Make
sure all wires are connected.
Make sure none of the
speaker wires are frayed, cut or
punctured.
If the system plays at low
volumes but shuts off as vol-
ume is increased, check the
following:
• Check all wires and con-
nections between receiver/
amplifier and speakers. Make
sure all wires are connected.
Make sure none of the
speaker wires are frayed, cut or
punctured.
• If more than one pair of main
speakers is being used, check
the minimum impedance
requirements of your
receiver/amplifier.
If there is low bass output,
check the following:
• Make sure the connections to
the left and right “Speaker
Inputs” have the correct
polarity (+ and –).
• Make sure that the subwoofer
is plugged into an active elec-
trical outlet and is turned on.
If there is no sound from
the surround speakers, check
the following:
• Check all wires and con-
nections between receiver/
amplifier and speakers. Make
sure all wires are connected.
Make sure none of the
speaker wires are frayed, cut or
punctured.
• Review proper operation of
your receiver/amplifier and its
surround sound features.
• Make sure the movie or TV
show you are watching is
recorded in Dolby surround. If it
is not, check to see if your
receiver/amplifier has other
surround modes you may use.

SUB175
OUTPUT TRANSISTOR CHANGE
Old Version:
In amplifiers with serial number lower then SUB01091226, the
output transistor was called D718/B688
New Version:
In amplifiers with higher serial numbers then SUB01091226 new
output transistor is used D1047/B817.
In case a (TLX) SCS175 SUB amplifier is for repair, replace
the output transistor to the new type.
