Remove the terminal cover plate
Loosen the two screws (do not remove) on the top terminal
cover plate and remove the cover plate.
• If a 70 V/100 V line distribution amplifier is being used,
such as the Extron XPA 2001-70V or XPA 2001-100V, the
cover plate is no longer needed since the included CPX 120
transformer cover plate will be installed in its place.
• If the 70 V/100 V line distribution system is not being
installed, retain the cover plate and proceed to step 6b.

Connecting wires to the CPX 120
terminal block
The transformer side of the CPX 120 cover plate has a
7-connector terminal block. Route the two wires from the
amplifier through the cover plate hole to the transformer side.
The black negative (-) wire attaches to the "COM" terminal,
and the red postitive (+) wire attaches to the desired terminal
tap.
COM 16 W
COM NC
N Installation in a plenum-rated environment
requires a wire gauge of 12 AWG to 18 AWG.
Pull the speaker wires from the conduit if a conduit is used.
Strip 3/16" (5 mm) from the wire ends, keep the wire end
strands together by twisting them (do not tin the wires), and
secure the wires to the appropriate taps on the terminal
block's captive screw connectors as indicated on the tap
label. Use a small flat blade screwdriver to tighten the
terminal block screws. See the note below for wiring
additional speakers.
N Route the speaker wires from the second speaker
through the cover plate hole to the transformer
side and twist the black negative (-) wires together
and twist the red positive (+) wires together before
inserting them into the terminal block. Additional
speakers can be daisy chained this way.
N Be sure to observe the 70 V or 100 V system
designation as indicated on the label.
N Wiring two speakers in parallel requires that the
maximum wire gauge not exceed 16 AWG. In a
single speaker installation the wire gauge should
not exceed 12 AWG.
When using flexible conduit, insert the conduit into the cover
plate opening using an appropriate conduit adapter and
secure the conduit to the plate as shown in the following
illustration.
