Analog Receiver/Processor – Speaker-Level Connections
Use this installation method
only with an analog receiver/
processor that does not have
digital processing or bass
management, and also does
not have a subwoofer output
or a volume-controlled preamp
(line-) level output:
Connect the speaker wires for
both your main left and right
speakers, and for the sub-
woofer, to the same speaker
terminals on your receiver or
amplifier. The wires may be
joined by twisting together the
bare ends of the two leads
that will be connected to each
terminal on the receiver/
amplifier, as shown in the
diagram. This procedure
should be done only four times
(involving a total of eight bare-
wire ends), and only for those
wire ends that are being con-
nected to the terminals on
your receiver/amplifier.
It is
important that you avoid join-
ing any other wires.
Do not
twist together
wire ends that
are being
inserted into
terminals on any
speaker or on the
subwoofer. Do not twist
together wire ends that will be
used for any speakers other
than the front left and right
speakers or the subwoofer.
Refer to the connection dia-
gram for guidance.
Twist together the (+) leads at
one end of the speaker wires
that you have designated for
the left front speaker and for
the left high-level inputs on
the subwoofer. Insert the
joined (twisted) wires into the
left front (+) terminal on your
receiver/amplifier. Connect the
free end of the (+) lead for the
left front speaker to the (+) ter-
minal on the back of the
speaker. Connect the free end
of the (+) lead for the left input
on the subwoofer to the left
binding-post terminal. Repeat
this process for the (–)
connections for the left front speaker and left input on the
subwoofer, and then for the (+)
and (–) connections for the
right front speaker and right
high-level inputs on the sub-
woofer.
Connect your receiver or
amplifier’s center and sur-
round speaker terminals to the
corresponding terminals on
the back of your center and
surround speakers.
