PCI 7DC RB / BACK CAN PCI 7DC RB
PCI 7DC RB Installation Guide
PCI 7DC RB 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 amplifier 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 of the back can into a typical
2" x 8" joist ceiling with 16" centers, with drywall/plasterboard not yet installed.
After the back can and drywall is installed, the PCI 7DC RB loudspeaker can be wired and installed, and the paint mask added for 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 offer
optimum acoustic performance for the listening environment and audio
system, and that is also practical and aesthetically pleasing. The location
should also allow enough room for the speaker wire to enter the back can at
one end.
2. Position the brackets as shown in Fig. 1, making sure that the lower faces of the
brackets are flush with the lower face of the ceiling joists. Secure each bracket
to the ceiling joist using four screws per bracket.
3. With the help of an assistant, carefully lift the back can to the chosen location
between the ceiling joists, and lift and slide it into place, until it is supported
by the four brackets and centered between them (Fig. 2).
4. Secure the back can to the brackets, using four screws per bracket.

Wiring
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.
(Note that the speaker wire connections are made to the internal terminals inside
the back can.)
The screw 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. 3). 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. Pull out the speaker cables and strip off approximately 8 mm (¼") of the
outer protective layer from each conductor.
4. The positive wire from your amplifier should go to one of the red (positive)
terminals inside the back can (Fig.4). The negative wire from your amplifier
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 so they will not move and touch
the speaker cone when it is installed.
