INSTALLING THE LOUDSPEAKERS
6. Prep the speaker wire by stripping 1/4"-1/2" from each speaker lead.
Twist the strands or tin the leads with solder to ensure there are no stray
strands that could short and possibly harm the amplifier.
7. If you've chosen to use insulation behind the loudspeaker, place it
through the hole and center it on the opening. If using paper-backed
insulation, it should be placed so that the paper side is away from the
loudspeaker.
8. The speaker has black and red
spring-loaded connectors (Figure 3).
Black is for the negative (-) wire and
red for the positive (+). It is important
to observe correct wiring polarity.
This is especially important for the
Stereo Input (SI) Loudspeaker. If you
have wire other than black and red,
make sure you connect it the same
on the amplifier end as the speaker
end. Failure to do so will adversely
affect the loudspeakers' performance.
9. Once the speaker wires are
connected, carefully slide the
loudspeaker into the opening hole
(Figure 4). While holding the speaker
in place, tighten the mounting screws
to secure the speaker to the drywall.
We recommend using a motorized
screwdriver. Be careful not to over
tighten. The CM loudspeakers feature
spring loaded mounting clamps that
allow the speaker to remain flush
with the ceiling, even if the
drywall shifts or expands.
NOTE: DO NOT CARRY THE SPEAKER
BY THE TWEETER OR TWEETER
BRIDGE. THIS MAY DAMAGE THE
SPEAKER.
