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 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.

Installation and Wiring

Figure 4: Speaker mounting plate

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).

Figure 14: Mount speaker into ceiling

Figure 15: Tighten mounting tabs

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.
