Figure 2: Bottom of speaker

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

hardware needed for either suspended ceil-

ings or sheetrock ceilings is included. The

ceiling speaker assembly is held in place by

mounting tabs that securely grip the ceiling

material. Input wiring is attached to a remov-

able terminal block connector that can be

pre-wired if necessary before speaker installa-

tion to speed up the installation process.

INSTALLATION NOTE: USE OF OPTIONAL

ROUGH-IN ACCESSORIES

For most installations, no additional hard-

ware is needed. However, a two-step installa-

tion procedure that is sometimes used for

installation 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 pro-

duction-line style installation 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 material is generally cut with a

router-type cutting tool, using the plate ring as

a cutout guide. The mounting plate is illustrat-

ed 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 accesso-

ry 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

ceiling 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 relat-

ed 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 ceil-

ing 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 appro-

priate 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’s 4 terminals are num-

bered and marked on the connector. Pins 1 and

2 are positive (+); pins 3 and 4 are negative (–).

(Pin 1 is connected to Pin 2 and Pin 3 is con-

nected to Pin 4 inside the speaker.) Pins 1 and

4 are used as daisy-chain connections to other

loudspeakers. Two possible layouts for wiring a

group of speakers are described below.

1. Wiring in parallel. Connect the wire

pair of the subsequent speaker to pins 2 and

3. When one input connector is removed,

subsequent speakers will remain connected.

See Figure 9.

2. Daisy-chaining. Connect the wire pair

of the subsequent speaker to pins 1 and 4.

When one input connector is removed, sub-

sequent speakers will also be disconnected.

See Figure 10.

INSTALLATION NOTE: SUBWOOFER

POLARITY

When adding a subwoofer, be sure to observe

the correct polarity. The C10.1 subwoofer has

been designed for optimum performance

when used with the C4.2. In order to maxi-

mize the low frequency output when used

with the C8.2, C8.2LP or C8.2HC, the polarity

of the C10.1 subwoofer should be reversed.

See Figures 11 and 12.

When all wiring has been completed to the

connector, plug the connector into the socket

in the speaker’s terminal cup. See Figure 13.

Tighten all screws to eliminate vibration.

Step 4: Secure the Cable to the

Speaker (Figure 14)

Fully loosen the horizontal screw shown in

Figure 13, then the strain relief screws. Run

the wires through the opening in the fitting

and plug the input connector into the speak-

er’s terminal block. Then tighten the strain

relief fitting as follows:

1. If plenum cable is used, slide the wiring

through the strain relief fitting on the termi-

nal cover plate (Figure 14). Hold the strain

relief fittings tight around the cable. Tighten

the strain relief screws first, then the hori-

zontal screw. In the cases of insulated

speaker 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.

2. If the installation used f lexible (BX) or rigid

(EMT) conduit, an alternate conduit fitting

can be used. See Installation Note and

Figure 15 below.

INSTALLATION NOTE: ALTERNATE

CONDUIT FITTINGS

Some cases require alternate fittings, many of

which are available through most electrical

suppliers. Simply remove the existing fitting

by unscrewing the two hold-down screws,

exposing a 7/8-inch (22 mm) knockout hole.

Then install the alternate fitting. Make sure to

always use a listed fitting in accordance with

your area’s building codes and regulations.

INSTALLATION NOTE: CEILING TILE

CAUTION

When mounting the units into 2'×2' or 2'×4'

suspended ceiling tiles, DO NOT install them

in lightweight fibreglass-type tiles without

full secondary support for the speaker as

noted in Step 6. Such tiles are not designed

to support any substantial weight. Speaker

installation without secondary support will

cause the tile to sag and distort, even with

the tile bridge installed. The secondary sup-

port line at the rear of the speaker MUST be

strung taut in these situations and MUST

remove most of the force of the speaker on

the tile to ensure that the speaker does not

deform the tile.

Step 5: Mount the Speaker Into

the Ceiling (Figure 16)

Push the speaker into

the ceiling 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 quar-

ter-turn rotates the

attachment tabs out-

ward. The remaining

turns tighten the tabs

down onto the back

of the ceiling surface

(see Figure 17).

Figure 17: Tighten mounting tabs

INSTALLATION NOTE: MOUNTING TABS

For each attachment screw, first turn one

half-turn counterclockwise to release the

mounting tab from its guide.

Step 6: Connect an Auxiliary

Support Line (Figure 18)

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 19)

The tap selector switch is located on the

front baff le. Adjust the speaker to the appro-

priate tap setting before installing the grille.

In some 70V/100V constant voltage installa-

tions it is advisable to leave the grilles off if

final speaker audio level balance adjust-

ments 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 3.7 W at both 70.7V

and 100V, with a 1.8 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 20)

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 20).

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 por-

tion at a time until the grille is removed.
