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.

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.
