Use the POLARITY switch to
maintain proper acoustic
summation with the main
speakers. Listen to your PS
subwoofer and main speakers
with the switch on "Normal" then
listen to the same material with
the switch on "Reverse". Decide
which way sounds better and
leave the switch in this position.
You should repeat this procedure
if you move your PS subwoofer to
another part of the room.
ALC PROTECTION CIRCUITRY
Your PS series amplifier has a
built in Automatic Level Control
circuitry that comes on
automatically when subjected to
high input signal levels. It prevents
the subwoofer driver from being
damaged by accidental miss-use,
assuring you of many years of
excellent performance.
GENERAL CARE
Use a damp cloth for cleaning
your PS subwoofer cabinet. Do
not use detergents or other
cleaners.
TROUBLESHOOTING / SERVICE
Your PS subwoofers should
only be serviced by an
authorized JBL repair station.
Do not attempt to remove the
grille. It is fixed and should only
be removed by qualified
personnel. Removing the grille
may void your warranty.
Woofers are replaceable by
repair station only. Do not
remove the amplifier from the
cabinet. There are no user
serviceable parts inside.
Before seeking service for your
PS subwoofer, please re-check all
connections as outlined in this
manual. Verify that your AC wall
power source is working properly
by checking with another
appliance.
