The EVID™ mounting system has been
designed so that, if necessary, the installation
can be done from beneath the ceiling. In some
cases with a suspended ceiling grid, however,
it may be easier to access from both the top
and bottom of the ceiling tile during the
installation process. Typical installation hard-
ware needed for either suspended ceilings or
sheetrock ceilings is included. The ceiling
speaker assembly is held in place by mount-
ing tabs that securely grip the ceiling materi-
al. Input wiring is attached to a removable
terminal block connector that can be pre-
wired if necessary before speaker installation
to speed up the installation process.
INSTALLATION NOTE: USE OF OPTIONAL
ROUGH-IN ACCESSORIES
For most installations, no additional hardware
is needed. However, a two-step installation
procedure that is sometimes used for installa-
tion into sheetrock ceilings can be made easier
by the use of the optional RR and RPK series
of rough-in accessories before the ceiling
material is installed. The rough-in accessories
provide a cutout guide when many holes are
to be made in a production-line style installa-
tion and to ensure the speakers are positioned
correctly as the holes are cut in the sheetrock.
Depending on the requirements, two types of
rough-in accessories are available.
RR Series Mounting Plates
RR series plates are made of flat sheet metal
with holes to attach to the joists or trusses of a
building structure. The holes are drilled for
nails or screws at 16 inches (406 mm), 20 inches
(508 mm) and 24 inches (610 mm) on-center.
The installer can drill other holes as needed up
to a maximum of 24-3/4 inches (630 mm)
apart. The sheetrock installs over the plate, and
the plate provides a template for a blind cutout
of the hole in the sheet rock. The ceiling materi-
al is generally cut with a router-type cutting
tool, using the plate ring as a cutout guide. The
mounting plate is illustrated in Figure 4.
RPK Series Kits
The RPK series rough-in kit contains a RR
series plate with a standard 2 gang electrical
box mounted on the top with an attached
short length of flexible conduit which con-
nects to the ceiling speaker conduit clamp on
the speaker’s rear terminal cover. This acces-
sory allows for rigid conduit to be run to the
box on the rough-in plate before the speaker
or any sheetrock is installed. After the
sheetrock is installed the speaker can be wired
up and mounted all from below the ceiling.
The RPK mount system is shown in Figure 5.
INSTALLATION NOTE: CONTROLLING
VIBRATION
Because of their high performance, EVID ceil-
ing loudspeakers can generate substantial
vibration, which can cause buzzing in loose
sections of the ceiling structure. Depending
on the character of the ceiling tile and related
components, dampening material may need
to be used under the tile rails or the edges of
the tiles to eliminate rattles.

Figure 5: RPK mounting system

Step 1: Cut the Hole (Figure 6)
For suspended tile or sheetrock ceilings, cut
out the hole either by tracing the cardboard
template or with a circular cutter set to the
appropriate cutout size. If the wire has been
pre-installed, pull the wiring through the
cutout hole.
Step 2: Install C-Ring and/or Tile
Rails (Figure 7)
All EVID speakers come packaged with two
types of backing hardware: a C-ring and two
tile rails.
For suspended ceiling installations, insert
the C-ring through the hole cut in the ceiling
tile. Place the C-ring around the hole with the
tabs located as shown in Figure 7. Insert the
tile rails through the cut hole in the ceiling
tile. Snap the two rails into the two tabs in the
C-ring and align the rails so that the ends
extend OVER the T-channel grid on the side
of the tile. Secure the rails onto the C-ring
tabs by inserting a screw though each tab into
the rail, as shown in Figure 7.
INSTALLATION NOTE: TILE RAILS AND
C-RING
Each speaker comes with two tile rails which
are designed to fit either standard 24-inch-
wide or 600-mm-wide tiles. It is important to
note that the tile rail pieces do not actually
attach to the T-grid struts. The ends of the
rails sit OVER the T-grid strut. Normally, the
tile supports the rails. The tile rails are pre-
punched at regular intervals with holes along
their length. This allows the C-ring to be posi-
tioned at any point along the rail. If the tile
comes out or falls apart, the ends of the sup-
port rails fall onto the T-grid, which prevents
the speaker assembly from falling.
Always use all included support hardware
when installing into suspended ceiling tiles to
make sure the installation is secure.
For sheetrock ceiling installations, the C-
ring should be used by itself to reinforce the
ceiling material and to spread out the pres-
sure from the speaker hold-down tabs. Guide
the C-ring through the cut hole in the ceiling,
and place it on the back side of the hole
before inserting the speaker.
Step 3: Attach Wiring to the
Terminal Connector (Figure 8)
Insert the bare end of wire into the appropri-
ate connector terminals as described below
and screw down the hold-down screw until
tight, using a small screwdriver.

INSTALLATION NOTE: CONNECTOR
WIRING GUIDELINES
The input connector contains 4 terminals.
These are numbered and marked on the con-
nector. The label located on the terminal cover
plate list the pin functions. Pins 2 and 3 are the
“+” and “-” inputs to the loudspeaker. Pins 2
and 3 are connected to pins 1 and 4, respective-
ly (Pin 1 connects to Pin 2 and Pin 3 connects to
Pin 4) inside the speaker. Pins 1 and 4 are used
as daisy-chain connections to other loudspeak-
ers. There are two possible layouts for wiring a
group of speakers. Use the wiring pattern that
accommodates your installation best.
To wire the system in parallel, connect the
wire pair of the subsequent speaker to pins 2
and 3 (in parallel with the input wire pair). In
this hookup scheme, no wires get connected
to pins 1 and 4. See wiring diagram in Figure
9. To daisy-chain the wiring using pins 1 and
4, connect the wire pair of the follow-on
speaker to pins 1 and 4. See wiring diagram
in Figure 10.
When all wiring has been completed to the
connector, plug the connector into the socket
in the speaker’s terminal cup. See Figure 11.
Remember to also tighten any open screws to
eliminate and vibration.
Step 4: Secure the Cable to the
Speaker (Figure 12)
Fully loosen the horizontal screw shown in
Figure 11. Then loosen the strain relief screws
(see Figure 11). Run the wires through the open-
ing in the fitting. Depending on whether con-
duit is used in the installation, the strain relief
can be tightened in two ways. Choose whichev-
er is best for your application.
1. If conduit is not used in the installation,
slide the wiring through the strain relief fit-
ting on the terminal cover plate (Figure 12).

Figure 12: Secure cable through fitting

In the cases of bare wire and plenum cable,
it is often possible to provide acceptable
strain relief force by simply tightening the
strain relief screws onto the terminal cover
plate. Reinsert the horizontal screw that
was previously removed, and tighten the
two horizontal screws, clamping the wire
securely between them.
2. If the installation used flexible (BX) or rigid
conduit, the supplied fitting accommodates
up to 3/8-inch (9.5 mm) diameter material.
Slide the wiring through the fitting and in-
sert the conduit into the strain relief (Figure
13). Then tighten the two horizontal screws
that clamp the fitting together, clamping the
conduit securely between them.
After all wiring to the speaker has been com-
pleted, close the hinged terminal cover and
tighten the hold-down screw (see Figure 11).
INSTALLATION NOTE: ALTERNATE
CONDUIT FITTINGS
In some cases, alternate fittings are required,
such as for larger-diameter conduit or to meet
specific code requirements. The fitting provid-
ed can be replaced with a number of standard
fittings available through most electrical sup-
pliers. Simply remove the existing fitting by
unscrewing the two hold-down screws, expos-
ing a 7/8-inch (22 mm) knockout hole. Then
install the alternate fitting. Make sure to always
use the proper fitting in accordance with your
area’s building codes and regulations.
Step 5: Mount the Speaker Into
the Ceiling (Figure 14)
Push the speaker into the ceiling through the
hole until the front baffle rim is flush with the
ceiling. Tighten the mounting tabs by turning
the screw clockwise until the speaker is secure.
Please note that the first clockwise quarter-
turn rotates the attachment tabs outward. The
remaining turns tighten the tabs down onto
the back of the ceiling surface (see Figure 15).

INSTALLATION NOTE: MOUNTING TABS
For each attachment screw, first turn one half-
turn counterclockwise to release the mount-
ing tab from its guide.
Step 6: Connect an Auxiliary
Support Line (Figure 16)
Note the support ring on the back of the
speaker. The ring allows for connection to a
independent and secure anchor point.
Construction codes often require the use of
this secondary support point.
Step 7: Adjust Tap Selector
(Figure 17)
The tap selector switch is located on the front
baffle. Adjust the speaker to the appropriate
tap setting before installing the grille. In some
70V/100V constant voltage installations it is
advisable to leave the grilles off if final speak-
er audio level balance adjustments are to be
made later. After the levels are adjusted the
grilles can then be installed.
EVID™ C4.2, C8.2 and C8.2LP
In addition to the 8-ohm setting, the power taps
are 30 W, 15 W, 7.5 W, and 3.75 W at both 70.7V
and 100V, with a 1.88 W tap for 70.7V only.
EVID™ C8.2HC and C10.1
In addition to the 8-ohm setting, the power
taps are 60 W, 30 W, and 15 W at both 70.7V
and 100V, with a 7.5 W tap for 70.7V only.
Step 8: Attach the Grille (Figure 18)
INSTALLATION NOTE:
GRILLE SAFETY FEATURE
EVID grilles features a unique safety tether to
prevent the grille from falling if the grille is
removed or comes loose after installation.
First, install the grille’s safety tether by
pushing the grille fastener into the hole in the
front of the baffle (see Figure 18). Second,
press the grille into place until the front of the
grille is flush with the rim of the baffle. Make
sure the grille is securely seated to prevent it
from vibrating loose.
If you need to remove the grille, the easiest
way is to insert two bent paper clips or other
pointed objects into holes in the grille, then
apply slow even pressure to pull down on the
grille until that section of the grille comes out
slightly. Continue the same procedure around
the perimeter of the grille, loosening a portion
at a time until the grille is removed.

If the speaker is installed in an area where
the interior design requires a color match,
these speakers are simple to paint. The
speakers can accommodate almost any type
of latex or oil-based paint. The bezel/rim can
be painted before installation or after mount-
ing into the ceiling.
Painting Process
Clean the rim and grille with mineral spirits
or other light solvent. Do not use harsh sol-
vents such as gasoline, kerosene, acetone, or
other chemicals. If you use these cleaners you
may permanently damage the enclosure.
Also, don’t use abrasives products such as
sandpaper or steel wool.
Either by rolling or spraying, apply two or
more thin coats of paint. If you are spraying,
hold the spray can at the angles shown in
Figure 19.
If you are painting the grille also, you must
first remove the internal grille cloth. Spray
painting is strongly recommended. If the
grille is rolled or brush painted, the grille
may become clogged with paint and the
sound quality will suffer. After the paint has
dried, replace the internal grille cloth.
If you wish to paint the speaker along with
the ceiling after installation, insert a plastic or
cardboard paint shield into the front of the
speaker to mask the drivers and internal baf-
fle, paint the speaker, then remove the shield.

Selecting and Positioning
Ceiling Loudspeakers
Several key criteria determine the type and
quantity of ceiling speakers to employ in a
job. Specific EVID™ Ceiling Series models
accommodate each job, depending on how
these criteria are specified.
• Room size
• Coverage density desired
• Coverage angle specification of the speaker
• Ceiling height
• Audio program material being played
In the traditional approach to overhead-
distributed systems, loudspeakers are located
in a grid arrangement whose dimensions are
dictated by the room height and the directivity
of the speaker elements. Two basic placement
patterns prevail: square spacing and hexago-
nal (or crisscross) spacing. See Figure 20.
In addition to the spacing pattern, the
designer must choose between three cover-
age density types, designated respectively as
edge-to-edge, minimum overlap and center-
to-center. The greater the overlap, the more
uniform the coverage. The illustration below
shows these various layout patterns.
Ceiling Systems: Size vs. Coverage
In the past, system designers usually speci-
fied 8-inch cone loudspeakers for distributed
overhead systems, at least in part because
they represented the traditional choice. The
EVID systems, however, allow for far more
flexible options.
In many cases, you can achieve excellent
results — at a significant savings — by using
4-inch transducers. This is especially true in
jobs that do not require extended low-end
response or high SPL levels. 4-inch transduc-
ers, such as those used in the C4.2, offer wider
dispersion to allow for fewer speakers to be
employed in the job. For example, due to its
smaller cone diameter, the C4.2 exhibits signif-
icantly wider dispersion (130 degrees) than
the C8.2 (110 degrees) at the -6 dB points.
The effect of this characteristic on an over-
head system is indicated in Figure 21. In
replacement applications where existing
speaker positions are used, the C4.2 (shown
in angle A) offers greater overlap and, thus,
more uniform coverage than an older con-
ventional 8-inch unit (shown in angle B).
When specifying a new system, you can take
advantage of the C4.2’s wider dispersion to
decrease the number of speakers required to
cover a given area. This will result in even
greater savings.
Of course, the C4.2 is somewhat less sensi-
tive than the 8-inch C8.2. The difference is
–7 dB. The C4.2 will also have slightly
reduced low-frequency capabilities below 90
Hz. However, neither of these factors is a sig-
nificant problem in many distributed sys-
tems. The C4.2 is conservatively rated to han-
dle 50 watts of continuous power equal to or
greater than most other brands of 8-inch
units, so its continuous SPL output will be
more than adequate. Moreover, its low-fre-
quency output can easily be augmented with
the addition of the C10.1 subwoofer. For these
reasons, the C4.2 represents a great way for
you to provide good audio coverage while

maintaining a competitive edge in price
quotes in installations that do not need the
extended performance of the larger models.
SPL Requirements: How Loud?
The EVID C8.2 is a great speaker to use when
higher SPL is required. The fidelity and band-
width of the unit is substantial and is ideal
for applications requiring high quality fore-
ground music reproduction. The C8.2 has
substantial low frequency energy down
below 60Hz. This is more than sufficient for
most applications.
Layout: How Many?
The chart below shows the effective coverage
diameter of the EVID models assuming a 4-
foot listening plane height. Using these fig-
ures you can lay out a coverage pattern for
the job after deciding the overlap criteria
described earlier on page 10.

C8.2 11.5' 23' 45' 57'
C8.2HC 6.5' 12' 24' 30'
C10.1 180°coverage
Use of Subwoofers
The C10.1 subwoofer can add considerable
low-frequency performance to any EVID
installation. It is important to note that the
C10.1 subwoofer depends on the ceiling and
walls to properly load itself and to reinforce
its bass output. Correct positioning is impor-
tant to get maximum impact.
In smaller rooms when a single C10.1 is
used, a center or near-center position is best.
This gives the most even coverage. For larger
rooms where more than one C10.1 are
employed, the added effect of the room’s
walls can be used. In such a space, position
the subwoofers evenly throughout the room
and a few feet from the wall or corners. The
added loading of the walls will enhance the
response in these larger areas.

Troubleshooting Table
Problem Possible Causes Action
No output Amplifier Make sure the amplifier channel is being fed an input
signal (preferably via a “signal input”indicator on the
amp).
Check that the amplifier channel’s volume is turned up.
Connect the speaker and cable, which had no output
to another amplifier channel, making sure an input
signal is fed to the new amp channel. If you then get
output, the problem was the amplifier channel. If not,
then the problem may be in the cable or speaker.
Speaker cable(s) Replace the cable(s) connecting the loudspeaker
system and amplifier.
Questionable or Faulty connection Check all cabling for proper connector contact. A bad
intermittent out- connection can result in intermittent contact or
