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 bot-

tom of the ceiling tile during the installation

process.Typical installation hardware needed for

either suspended ceilings 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

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 proce-

dure that is sometimes used for installation into

sheetrockceilings can be made easier bythe

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 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 attachto the joists or trusses of a build-

ing 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

sheetrockinstalls over the plate, and the plate pro-

vides 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 illus-

trated 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 connects to the

ceiling speaker conduit clamp on the speaker’s

rear terminal cover.This accessory 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 speak-

er 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

loudspeakerscan generate substantial vibration,

which can cause buzzing in loose sections of

the ceiling structure. Depending on the charac-

ter 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

tworails 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 eachtabinto the rail, as shown in Figure

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 positioned at any point along the rail.

If the tile comes out or falls apart, the ends of

the support rails fall onto the T-grid, which pre-

vents 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 pressure 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)

Insertthe bareend of wire into the appropriate

connector terminals as described below and

screwdown the hold-down screw until tight,

using a small screwdriver.

WIRING GUIDELINES

The input connector’s 4 terminals are numbered

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 connected to Pin

4inside the speaker.) Pins 1 and 4 are used as

daisy-chain connections to other loudspeakers.

Two possible layouts for wiring a group of speak-

ers 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, subsequent

speakers will also be disconnected. See Figure

10.

INSTALLATION NOTE: SUBWOOFER

POLARITY

When adding a subwoofer,be sure to observethe

correct polarity.The C10.1 subwoofer has been

designed for optimum performance when used

with the C4.2. In order to maximize the low fre-

quency 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 speaker’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 terminal

cover plate (Figure 14). Hold the strain relief fit-

tings tight around the cable.Tighten the strain

relief screws first, then the horizontal 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 flexible (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 areavailable 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 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' sus-

pended ceiling tiles, DO NOT install them in

lightweight fibreglass-type tiles without full sec-

ondary 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 support line at the rear of the speak-

er 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 quarter-

turn rotates the attach-

ment tabs outward.The

remaining turns tighten

the tabs down onto the

back of the ceiling sur-

face (see Figure 17).

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 speak-

er.The ring allows for connection to a inde-

pendent 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

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 speaker

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 3.7 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 push-

ing the grille fastener into the hole in the front

of the baffle (see Figure20). 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

wayis 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

atime until the grille is removed.
