Dolby Pro Logic Line Level - JBL PowerBass PB12 Service Manual

PB12
Dolby Pro Logic (Non-Digital) – Line Level
Use this installation method for
Dolby Pro Logic applications
(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.
8
Make sure your receiver or
processor is configured
correctly: Make sure that the
subwoofer 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.
