When using plenum speaker wire without a conduit, insert
the wire through the cable clamp adapter (included) and
secure the adapter to the cover plate.
• If a seismic support line is being used, install the seismic
anchor ring (included) between the conduit adapter and
the CPX 120 cover plate as shown below.
• If the CPX 120 transformer cover plate is being installed,
proceed to step 6a, otherwise proceed to step 6b.
Strip 3/16" (5 mm) from the ends of the two speaker wire
leads (+ and -) coming from the transformer. Keep the
wire strands together by twisting them (do not tin the wires),
and secure the wires to the speaker’s input terminals while
observing the correct polarity.
Connect the red positive (+) wire to the + speaker terminal
and connect the black negative (-) wire to the - speaker
terminal as shown below. Proceed to step 7.

Route the wires from the amplifier to the speaker using the
same procedure for routing speaker wire (and conduit if
applicable) through the cover plate as described in step 3.
Strip 3/16" (5 mm) from the ends of the two speaker wire
leads (+ and -) coming from the amplifier. Keep the
wire strands together by twisting them (do not tin the wires),
and secure the wires to the speaker’s input terminals while
observing the correct polarity.
Connect the red positive (+) wire to the + speaker terminal
and connect the black negative (-) wire to the - speaker
terminal depending on whether one or two speakers are
being connected, as shown below.
