Speaker Connection
When we designed the PB10
and PB12 powered
subwoofers, our goal was to
offer the user the best possible
performance combined with
the most flexible and complete
installation options. Please
look over the following three examples to determine which
description best matches your
system and follow the
corresponding hookup
instructions.
To use the binding-post
speaker terminals with bare
wire, unscrew the collar until
the hole through the
centerpost is visible under the
collar.
Insert the bare end of the wire
through the hole in the post,
then screw the collar back
down until the connection is
tight. The holes in the center
of the collars are intended for
banana-type connectors.
Dolby Pro Logic (Non-Digital)-Speaker Level
Use this installation method for
Dolby Pro Logic applications
(not Dolby Digital, DTS

or
other digital processing),
where the receiver/processor
does not have a subwoofer
output or a volume-controlled
preamp (line-) level output:
Connect your receiver or
amplifier’s front left and right
speaker terminals to the left
and right terminals on the
subwoofer that are marked
“High Level In.” Connect the
left and right terminals on the
subwoofer that are marked
“High Level Out” to the
corresponding terminals on the
back of your front left and right
speakers.
Connect your receiver or
amplifier’s center, left and right
surround-speaker terminals to
the corresponding terminals on
the back of your center, left
and right surround speakers.
