JBL SCS150SI - Manual (Page 6)

Dolby Pro Logic (Non-Digital) – Line Level
Use this installation method
for Dolby Pro Logic appli-
cations (not Dolby Digital, DTS
or other digital processing),
where the receiver/processor
is equipped with a subwoofer
output, or a volume-controlled
preamp (line-) level output: Use RCA-type patch cords
to connect the line-level
subwoofer outputs on your
receiver or amplifier to the
line-level inputs on the
subwoofer. IMPORTANT: Do
not use the LFE input on the
subwoofer with Dolby Pro Logic processors. Note: If
your receiver or amplifier only
has one subwoofer output
jack, then you will need to use
a Y-connector (not included).
Plug the male end of the Y-
connector into your receiver
or amplifier’s subwoofer
output jack, and connect each
of the two female ends to
separate RCA-type patch
cords. Finally, plug the RCA-
type patch cords into the line-
level inputs on the subwoofer.
Connect each speaker to
the corresponding speaker
terminals on your receiver
or amplifier.
Make sure your receiver or
processor is correctly
configured to indicate that the
subwoofer is “On.”
Note for advanced users: If
your receiver/processor has a
built-in low-pass crossover
filter for the subwoofer output,
you may use the LFE input to
bypass the subwoofer’s
internal crossover.
Use this installation method
for Dolby Digital, DTS or other
digital surround processors:
Use the line-level input jack
marked “LFE” for the Low-
Frequency Effects channel.
Connect this jack to the LFE
output or subwoofer output
on your receiver or amplifier.
Connect each speaker to the
corresponding speaker
terminals on your receiver
or amplifier.
Make sure that you have
configured your surround-
sound processor for
“Subwoofer On.” The front
left, front right, center and
rear speakers should all be
set to “Small.”
