PRODUCT PREPARATION
AMPLIFIER SELECTION
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 0.8. In this case, 75 /
0.8 = 93.75 watts. Therefore, a standard 100 watt amp
would safely drive this load. To calculate the amount of
usable power an amp oers, simply multiply the rated
output by 0.8, i.e., 100 watts x 0.8= 80 watts.
WIRE GAUGE – 70V/100V SYSTEM
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.
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.
WIRE GAUGE – 8 OHM SYSTEM
When using Sonance Professional Series loudspeakers
in an 8 Ohm system, the total wire resistance should be
less than 10% of the speaker impedance. The speakers
are nominally 8 Ohms impedance, so your total wire
resistance should be no more than 0.8 Ohms.
In simple terms, the extra resistance from the wire will
have a very negative aect 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.
Please refer to the following chart (see Figure 1) when
deciding on the appropriate wire gauge for your
installation.

GRILLE PAINTING
Before You Begin
Sonance Professional Series In-Ceiling speaker grilles
completely cover the exposed speaker frame, so
only the grilles (not the speakers themselves) require
painting.
IMPORTANT: Mask the front flange of the speaker
before painting the wall or ceiling (see Figure 3).
Carefully remove the scrim cloth from the underside of
the grille. The scrim cloth is held in place with a light
tacking glue. Use a heating agent such as a heat gun or
hair dryer to soften the glue and carefully remove the
cloth, since you will need to replace it when you’re done
painting the grille. Be careful not to deform the cloth’s
shape while removing it - this will make it very dicult
to properly replace the cloth on the grille. Remove any
adhesive residue from the back of the grille before
beginning painting.
Painting The Grilles
1. Prime the grille with a metal primer/bonder in a
spray can. Carefully follow the manufacturer’s
directions on the can.
2. We recommend using water-based latex paint on the
grilles. Thin the paint with a proper thinning agent to
a ratio of 1:1 paint-to-thinner, and strain it through a
standard mesh strainer to remove any lumps.
IMPORTANT: Due to its increased durability, oil-based
paint should be considered for Professional Series
Speakers that are installed outdoors.
3. Use a small touch-up gun or cap-spray gun with a #3
tip for painting.
A. Set the nozzle with a medium to wide fan.
B. Set the pressure regulator to 60psi.
C. Lightly spray the front of the grille in three
quick strokes from approximately 10” away.
D. Let the paint set for a minute, then turn the
grille 90º and lightly spray the grille again in
three quick strokes. Repeat this step until all
four sides of the grille have been evenly painted.
4. While the paint is still wet, inspect the grille
and make sure that excess paint has not collected
underneath the grille frame, and that none of
the grille perforations are filled with paint. If any
are, use compressed air to blow the paint out of the
perforations.
IMPORTANT: If you find any grille perforations that
are plugged with paint after the paint has dried, use a
straight pin or sewing needle to carefully remove the
paint.
5. Once the paint has thoroughly dried, replace the
scrim cloth on the back of the grille and mount the
grille on the speaker.

STANDARD INSTALLATION
STEP 1
Cut a hole in the drywall using the supplied cutout
template (see Figure 4).
NOTE: For drop-ceiling instructions refer to page 7.
STEP 2
Connect the wires from your
amplifier to the Euroblock
connector (see Figure 5).
Pin 1 + Positive In
Pin 2 - Negative In
Pin 3 + Positive Out
Pin 4 - Negative Out
Strip approximately .1875” (5mm) of the insulation
o 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 (see Figure 6).
When using multiple speakers you can connect the
speakers either in parallel or in the loop through
method as shown (see Figure 7 and 8).
The included conduit clamp/wire strain relief can be
installed on the top or the side of the terminal cover
using either available knockout. Once the clamp is
installed, route the wires through the strain relief fitting.
Tighten the screws on the clamp to secure the conduit/
wires the wires. Make sure not to over-tighten the
screws and damage the wire.
NOTE: If square grilles are being used, the adapter
frame must be installed at this time.
STEP 3
Once all the wires are terminated. Plug the black
Euroblock connector into the back of the speaker (see
Figure 9).

Grille Installation
STEP 7
After the speaker is installed,
and transformer tap
adjustments are made, the
grille can be installed. The grille
is held in place by powerful
magnets on the speaker frame.
Place the grille against the
speaker and the magnets will
hold it firmly in place. When
properly installed, the grille
should make contact with the
wall all the way around the
speaker (see Figure 12).
STEP 6
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 (see Figure 11).
DROP CEILING INSTALLATION
STEP 1B
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 theC-bracket to the tile support rails as shown
(see Figure 13). After the C-bracket and tile support
rails are installed, follow Step 2 through Step 7 in the
standard installation instructions.
STEP 4
Make sure the Roto-Lock 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 (see Figure 10).
Note: The maximum clamp thickness 2” (50mm).
To achieve maximum thickness, unscrew and reverse
the foot of the Roto-Lock Clamps.
Note: For details on flex bracket go to

SAFETY PRECAUTION: Attaching the seismic tab to a
support line is recommended for additional safety.
IMPORTANT: Do not use power tools or overtighten
the screws as it may cause damage to the Roto-Lock
clamps.
STEP 5
Tighten the four screws on the front of the bae. The
Roto-Lock Clamps will rotate into position automatically
and begin clamping. When you notice resistance on the
four screws, the speaker has been clamped successfully.
The flange is designed to flex and conform to any small
imperfections in the ceiling surface. Do not overtighten
as this could damage the clamps.
