Back Can Installation
WARNING: This procedure requires the use of an assistant, and the use of personal protection equipment, such as safety glasses and gloves.
WARNING: To avoid potential damage to your loudspeaker, ensure that the power ampli er is switched OFF prior to connecting or disconnecting any cables.
WARNING: Make sure that there are no power lines, other cables, or plumbing such as water, sewer, gas lines in the chosen location.
The procedure below describes the installation and wiring of the PCI 7DC IW back can into a typical 2" x 4" stud wall with 16" centers, with drywall/plasterboard not
yet installed.
After the back can and drywall is installed, the PCI 7DC IW speaker assembly can be connected to the back can wiring and installed, and the paint mask added during
wall painting and finishing.

Procedure
Follow the procedure steps below in the order in which they are presented. Read all
the instructions before starting.
1. Locate a suitable mounting position for the loudspeaker that will o er
optimum acoustic performance for the listening environment and audio
system, and that is also practical and aesthetically pleasing.
2. Allow enough room for the speaker wire to enter the bottom cable gland, and
with enough room to tighten the screws that hold the brackets to the back can.
3. Install the four brackets onto the wall studs, and make sure the distance
between the top and bottom brackets is as shown in Fig. 1.
4. With the help of an assistant, carefully lift the back can between the brackets
(Fig. 2), with the cable entry at the bottom.
5. Make sure that the back can is plumb and level, and its front face is  ush with
the front face of the wall studs. Screw the 4 brackets to the back can.
6. Note: If you install the back can with the cable entry at the top, then the four
small brackets that accept the speaker assembly screws, need to be rotated
through 180 degrees. Undo the 2 small screws, and re-orient each small
bracket as shown (Fig. 2b).
Wiring the Back Can
WARNING: To avoid potential damage to your loudspeaker, ensure that the
amplifier is switched OFF prior to connecting or disconnecting any cables.
WARNING: Before switching the amplifier ON, double check that all connections
are secure and that the polarity is correct.
The speaker wire connections are made to the internal terminals inside the back
can. There are two internal tubes that allow the speaker wiring to be inserted and
to come out near the speaker terminals inside the back can. The speaker terminals
are pre-wired to an internal connector which attaches to the speaker assembly
when it is installed.
The speaker terminals are designed to take substantial high quality
loudspeaker cable.
1. Remove the cover from the back can by undoing the four screws holding it in
place (Fig. 3).
2. Install the speaker wire in through one of the cable glands, and leave enough
slack to make the connections (Fig. 4). Tighten the cable gland, and tie down
the speaker cable to prevent it moving and rattling in operation. Make sure
that the speaker cable does not come into contact with nails or screws that
might damage the insulation. A second cable gland is provided to allow a
second speaker cable run to be installed.
3. Strip approximately 8 mm (1/4") o the outer protective layer from each
conductor.
4. The positive wire from your ampli er should go to one of the red (positive)
terminals inside the back can (Fig.5). The negative wire from your ampli er
should connect to one of the black (negative) terminals. You can use the
other red and black terminals to run speaker wiring out of the other cable
gland and out to another speaker.
5. Make sure that the speaker cables are secured inside the back can so they will
not move and touch the speaker cone when it is installed.
6. The cover may be reinstalled until it is time for the drywall installation.
