5.3 Mounting the Speakers
To install the closed-back ceiling
speakers, do the following:
1. Place the C-ring over the hole cut in the ceiling tile (on the “ceiling”
side). Place it around the hole so that the tabs are located in parallel to the
tile edges (see
Figure 5
).

2. Place the tile rails on the tile and snap them into the two tabs on the
C-ring.
Align the rails so that the ends extend over the T-channel grid.
3. Insert a screw through each tab on the C-ring to secure the rails.
4. Connect the speaker wires to the appropriate connector terminals

and
screw the hold-down screws on the connector until tight

Wiring in parallel
: connect the wire pair of the subsequent speaker
to PIN 2 and PIN 3. When one input connector is removed,
subsequent speakers will remain connected (see
.
You can connect the speakers in the two following possible layouts:

)
Daisy-chaining
: connect the wire pair of the subsequent speaker to
PIN 1 and PIN 4. When one input connector is removed, subsequent
speakers will be disconnected (see
Figure 4
)
5. Plug the connector into the socket in the terminal cup of the speaker (see
Figure 6
).
6. Run the wires through the wires’ opening in the input terminal cover plug
and then into the terminal block connector of the speaker.
