Final Installation In New Or Existing Construction - Niles CM8SW Installation & Operation Manual

Final Installation in New
or Existing Construction
1. If it is possible to lay a batt of insulation
into the ceiling cavity, do so. Remember
to use equal amounts of insulation for
each speaker.
2. Separate the speaker wire so that at least
two inches of each conductor are free.
3. Open the no-strip terminal by applying
pressure to the red and black levers until
an audible "click" is heard.
4. Insert one unstripped wire fully into the
black and one into the red terminal. Pay
attention to the markings on the wire.
Each speaker must be connected to the
amplifier in the same way. If unsure,
see section "Speaker Phase" located on
the following page. Squeeze the red
and black levers until they click signify-
ing that they have locked into the wire.
5. Insert the no strip terminal into the
corresponding socket on the rear of the
speaker. Push it down until it locks in
place. The terminal will only fit in the
socket in one direction. If the terminal
does not properly seat, reverse the terminal
6. Connect the wire which runs to the
satellite speakers to the left and right
output terminals. Pay attention to the
markings on the wire.
7. There are four clamps or mounting
"dogs" which hold each speaker in
place. The dogs are tightened via four
front-baffle screws. To install the speaker,
first rotate the dogs inward. Insert the
speaker into the cutout and tighten the
dogs by turning the screws clockwise.
DO NOT OVER TIGHTEN THESE
SCREWS. Over-tightening the clamps
may make the grille difficult to install.
(See Figure18).
NOTE: The screws will be easier to turn if
you "prime" them first. Before installing each
speaker, turn the screws in and then turn
them back out to their original positions.
8. Setting the High Pass Filter
When the "SAT" filter is in the CUT
position, all of the bass energy will be
produced via the CM8SW. When the
switch is in the FULL position, both the
satellite speakers and the CM8SW will
reproduce the bass signal. Typically,
satellites with woofers that are 5-3/8" or
smaller will sound best with the filter
on. Listen to a loud and well recorded
bass passage to evaluate.
9. Setting the Subwoofer Low Pass Filter
With the "SUB" switch in the 100Hz
position, the CM8SW will only repro-
duce bass below one hundred cycles.
When the switch is in the 140Hz posi-
tion, the CM8SW will reproduce bass
below 140 cycles. Depending on the
size of the room, the type of satellite
speaker and the subwoofer position,
you will prefer one setting to the other.
Listen to a loud and well recorded bass
passage to evaluate.
10.Install the grille into the speaker. The
grilles should fit snugly. If you have diffi-
culty fitting them in, try loosening the
mounting dog screws slightly (excessive
tightening can distort the shape of the
frame holding the grille in place).
