Connecting the Speaker Level (High Level) Inputs
For older receivers with no LFE or Subwoofer outputs, run speaker wire from your re-
ceiver's front left and right speaker level outputs to the left and right speaker level in-
puts on the subwoofer. Connect the front left and right surround speakers in parallel
with the subwoofer.
NOTE: To avoid possible output problems, do NOT use the "speakers B" out-
put to attach the subwoofer to a receiver.
IMPORTANT: All speakers in a system must be connected with the same po-
larity. Polarity is indicated by a color stripe on the insulation, by ridges mold-
ed into the insulation, or by the colors of the wire - one copper and one silver.
Strip the insulation from the speaker wire ends to reveal the bare conductors
before connecting to a speaker, subwoofer or receiver. Always connect the red
(+) terminal on the receiver to the red (+) terminal on the Subwoofer, and con-
nect the black (-) terminal on the receiver to the black (-) terminal on the Sub-
woofer. The same is true for hooking up the Receiver outputs to the Front
speakers: red (+) to red and black (-) to black.
