When using the CM860 and CM660 in an 8 ohm system the total wire
resistance should be less than 10% of the speaker impedance. The
CM860 and CM660 nominally 8 ohms impedance, so your total wire
resistance should be no more than 0.8 ohms.
The Sound Advance Prommercial series speakers possess extremely
smooth and predictable off-axis frequency response. The chart below
shows how far apart the speakers can be placed in a distributed audio
system. The calculations are based on +/- 45 degrees of coverage
from the speaker, and listener ear heights of 62" for standing and 40"
for seated.
In simple terms, the extra resistance from the wire will have a very
negative affect on the sound quality of the speaker. The sound can be
less dynamic, definition of bass frequencies can be reduced, and in
extreme cases, the high frequencies can be attenuated. Amplifier
power is also wasted in the wire, reducing the maximum output level
of the system.

PAINTING THE SPEAKERS AND GRILLES
A M P L I F I E R
S E L E C T I O N
The Sound Advance CM860 and CM660 speakers feature a tough
weather-resistant ABS finish that may be painted to color match their
surroundings. Use a weather-resistant outdoor paint and a spray gun.
First remove the grille by carefully prying it away from the baffle. The
driver components must be protected from paint when spraying. If
necessary, you can fashion plugs by placing the speaker grille on a
piece of cardboard and tracing around the outside of the grille. Cut
just inside the line you drew on the cardboard and place the paint plug
on the speaker baffle. Remove the paint plug when you are finished
painting.
When choosing an amplifier the maximum number of speakers and the
output level of each speaker must be known. The sum of the tap
settings should never exceed 80% of the amplifier’s rated output. For
example, if there are 5 speakers and the taps are set at 15 watts, the
load would be 75 watts (5 x 15 watts = 75 watts). To arrive at the
needed power for this number of speakers, simply divide the total load
by .8. In this case, 75 / .8 = 93.75 watts. Therefore, a standard 100
watt amp would safely drive this load. To calculate the amount of
usable power an amp offers, simply multiply the rated output by .8,
i.e., 100 watts x .8= 80 watts.
The metal grilles may also be painted. Use very thin paint (5:1). It will
be easier to paint the grille while it is off the speaker. Avoid plugging
up the holes with excess paint.
W IR E G AU G E — 70/ 100 V O L T SY STE M
The most common wire used on commercial 70 volt systems is 18
gauge, 2 conductor, stranded, and jacketed without a shield.
The wire starts at the amplifier location and is paralleled at each
speaker location.
M A I N T E N A N C E
Wire length using 18 gauge is appropriate up to 700 feet with a 100-
watt load. If you double the load (sum of your tap settings), you will
reduce the footage by half, to 350 feet. Conversely, if you halve the
load, you may double the acceptable wire length, i.e., a 50 watt load is
safe over 1400 feet of 18 gauge. Stepping up to 16 gauge wire
extends the allowable run length by approximately 35%. For example,
a 100-watt load can go 700 feet on 18 gauge; the same load may be
placed on 1100 feet of 16 gauge.
No maintenance is required when installed in accordance with
installation and wiring guidelines described in this manual.

Step 1
Once all the wires are terminated. Plug the green input connector into
the back of the speaker.
Cut a hole in the drywall using the
supplied cutout template.
NOTE: For drop-ceiling instructions refer
to page 5.
Step 2
Remove the speaker from the
packaging, open the terminal cover
plate door and remove the green input
connector.

Connect the wires from your amplifier to
the input connector.

Strip approximately 3/16" of the
insulation off each wire. Insert the wire
into the correct square opening on the
connector. Use a small flat head
screwdriver to tighten the corresponding
screw to secure the wire.
Route the wires through the Strain Relief Fitting on the back of the
speaker. Tighten the screws on the strain relief to clamp the wires.
Make sure not to over-tighten the screws and damage the wire.
When using multiple speakers you can
connect the speakers either in parallel
or in the loop thru method as shown
below.

The included C-bracket and tile support rails should be used in all
suspended ceiling installations. The C-bracket and tile support rails can
also be used in installations when the speakers are mounted into
material that will not support their weight.
Insert the two tile support rails and C-bracket through the hole you
have cut. placing them as shown. Using the two screws that are
supplied, screw the C-bracket to the tile support rails as shown.
Step 5
Make sure the RotoLock clamps are in
the full clockwise position so that all the
clamps are tucked within the cutout
border. Insert the speaker into the hole
in the ceiling.
Note: The maximum clamp thickness is
1-1/4" (32mm)
SAFETY PRECAUTION
Attaching the seismic tab to a support line is highly
recommended for additional safety
Step 6
Tighten the four screws on the front of
the baffle. The RotoLock clamps will
rotate into position automatically and
begin clamping. When you notice
resistance on the four screws, the
speaker has been clamped successfully.
After the C-bracket and tile support rails are installed follow Step 2
through Step 7 in the standard installation instructions.
The flange is designed to flex and
conform to any small imperfections in
the ceiling surface. The screws should
not be tightened so far that the flange
bows out.
SAFETY PRECAUTION
Attaching the seismic tab to a support line is highly
recommended for additional safety
Step 7
At this step in the installation the
transformer tap selector can be set.
Depending on your installation you may
wait to set the volume of each speaker
until the system is completely installed.
After the speaker is installed, and
transformer tap adjustments are made,
the grille can be installed. Insert about
half of the grille into the groove at the
edge of the speaker. Gently fit the
remaining half of the grill into the
speaker by working your hands around
the speaker fitting the grille into the
groove as you go along.
Note: The torque applied to the
mounting screws can be adjusted for
proper grille fit.
