Electro-Voice Installation Manual 2016.05 | 09 | F.01U.177.705

Installation and Wiring
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 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 prewired 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 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 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 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.
Figure 4: Speaker mounting plate
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 speaker can be wired up and mounted all from
below the ceiling.

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 related components, dampening material may need to be used
under the tile rails or the edges of the tiles to eliminate rattles.
Step 1 — Cut the Hole
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.
Figure 6: Cut ceiling hole
Step 2 — Install C-Ring and/or Tile Rails
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.

Electro-Voice Installation Manual 2016.05 | 09 | F.01U.177.705

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 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 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
Insert the bare end of wire into the appropriate connector terminals as described below and
screw down the hold-down screw until tight, using a small screwdriver.
INSTALLATION NOTE: CONNECTOR

Figure 8: Tighten with screwdriver
WIRING GUIDELINES
The input connector’s four (4) terminals are numbered and marked on the connector. Pins 1
and 2 are positive (+); pins 3 and 4 are negative (–).
Note: Pin 1 is connected to Pin 2 and Pin 3 is connected 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, subsequent 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 maximize 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 input connector (A) into the
socket in the speaker’s terminal cup (B). See Figure 13. Tighten all screws to eliminate
vibration.

Step 4 — Secure the Cable to the Speaker
Fully loosen the horizontal screw (C) shown in Figure 13, then the strain relief screws (D). Run
the wires through the opening in the fitting and plug the input connector (A) into the
speaker’s terminal block (B). 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 fittings 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.
Figure 14: Secure cable through fitting
Figure 15: Alternate conduit fitting
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.

Step 5 — Mount the Speaker into the Ceiling
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 attachment tabs outward. The remaining turns
tighten the tabs down onto the back of the ceiling surface (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
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.

Caution!
Ceiling mount speaker’s safety cable
The safety cable should be installed with a minimum of 3-inches (76.2 mm) of slack.
Figure 18: Attach auxillary support line
Step 7 — Adjust Tap Selector
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.
Figure 19: Adjust tap selector (left: C4.2/C8.2/C8.2LP; right: C10.1/C8.2HC)
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
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 portion at a time until the grille is removed.

Troubleshooting
Problem Possible Causes Action
No output Amplifier Ensure the amplifier channel is being fed an input signal (preferably
via a signal input indicator on the amplifier).
Verify the amplifier channel’s volume is turned up.
Connect the loudspeaker and cable, which had no output to another
amplifier channel, ensuring an input signal is fed to the new amplifier
channel. If you then get output, the problem was the amplifier
channel. If not, then the problem is either the cable or the
loudspeaker.
Loudspeaker
cables(s)
Replace the cable(s) connecting the loudspeaker system and
amplifier.
Questionable or
intermittent output,
such as crackling
Faulty connection Ensure all cabling for proper connector contact. A bad connection can
result in intermittent contact or dramatically increased resistance,
which in turn can cause reduces output or noises unrelated to the
signal.
Improper power
tap setting
Verify the power tap setting under the loudspeaker grille is
appropriate for the installation and amplifier chosen.
Constant noise
such as buzzing,
hissing, or
humming
A faulty electronic
device in the signal
chain
Loudspeakers cannot generate these sounds by themselves; you may
have a faulty electronic device in the signal chain.
Poor system
grounding
Check and correct the system grounding, as required.
Poor low-frequency
output
Out-of-polarity
hookup between
multiple
loudspeakers
When two (2) loudspeakers are hooked up out of polarity (out of
phase), the low frequencies cancel each other out. Try reversing the
polarity of one (1) of the loudspeakers either by turning around a
dual-banana plug at the amplifier or by reversing the tip/sleeve leads
on the jack. Which ever condition results in greater low-frequency
output is the in-polarity condition.
If these suggestions do not solve your problem, contact your nearest Electro-Voice dealer or
Electro-Voice distributor.
