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.

6b Connecting wires from a low impedance amplifier to the speaker

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.

6a Connecting wires from the CPX 120 to the speaker

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.
