SUBWOOFERS
You may connect your subwoofers
in several ways depending on how
many subwoofer amplifier outputs
are available. Read the following
instructions carefully to insure
proper hook-up of your
subwoofers. Improper hook-up
can degrade performance or even
damage to your amplifier.
REFER TO SUBWOOFER
HOOK-UP DIAGRAM.
Note: 
You will need at least one
subwoofer amplifier channel to
drive your passive HT1S
Subwoofers.
Using two HT1S Subwoofers
(from single subwoofer
amplifier terminal output).
Connect the wire from the
amplifier speaker terminal marked
"Subwoofer" to the left-hand set
of Red and Black binding posts on
the 
first subwoofer. Make sure
you follow the Red (+) to Red and
Black (-) to Black convention.
Unscrew the right-hand binding
posts and remove the connecting
strap. Place the strap with your
owner's manual for safekeeping.
Run a second wire from the right
hand binding post of the 
first
subwoofer over to the second
subwoofer 
and connect to the
left-hand binding posts. DO NOT
remove the strap connecting the
second subwoofer's right-hand
set of binding posts. This results in
a series connection of your
subwoofers that will not damage
your amplifier. Your dual
subwoofer connection is complete.
See figures on page 7.
Using two HT1S Subwoofers
(from two subwoofer amplifier
terminal outputs).
If your amplifier is equipped with
two subwoofer outputs, you must
determine how they are wired. If
they are two parallel-wired outputs
from the same amplifier channel,
wire the subwoofers as in the
previous paragraph to only one
output.. If on th other hand, they
are two separate channels of
amplification, follow the hook-up
method described under "Using a
single HT1S Subwoofer". Connect
wires from one amplifier subwoofer
output terminal to the first
subwoofer's left-hand binding
posts 
leaving the connecting strap
in place on the right-hand binding
posts. Connect wires from the
other amplifier subwoofer output
terminal to the other subwoofer's
left-hand binding posts 
leaving the
connecting strap in place on the
right-hand binding posts. Your
dual subwoofer connection is
complete. See figures on page 7.
Using a single HT1S Subwoofer.
Connect the wire from the
amplifier terminal marked
"Subwoofer" to the left-hand set
of Red and Black binding posts on
the subwoofer. Make sure you
follow the Red (+) to Red and
Black (-) to Black convention. DO
NOT 
remove the strap connecting
the right-hand set of binding posts.
Your single subwoofer connection
is complete.
