JBL Studio S120PII, Service Manual

Page: 6 / 28

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:
Make sure that the LFE toggle
switch
™ on the subwoofer is
in the “Normal” position. Do
not use the “LFE” position
with Dolby Pro Logic-only
processors.
Note: If your receiver or
amplifier only has one
subwoofer output jack,
then you may connect the
subwoofer output on your
receiver/preamplifier to either
the left or right Line Level
input
¶ on the subwoofer. It
makes no difference which
jack you choose.
Connect each speaker to the
corresponding speaker
terminals on your receiver or
amplifier.
Make sure your receiver or
processor is configured cor-
rectly: Make sure that the sub-
woofer is configured as “On.”
Note for advanced users: If
your receiver/processor has
a built-in low-pass crossover
filter for the subwoofer output,
then the LFE switch
™
should
be set to the “LFE” position to
bypass the subwoofer’s
internal crossover.
