Installation and Wiring

INSTALLATION NOTE: CONTROLLING VIBRATION

Because of their high performance, EVID FM Series loudspeakers can generate substantial vibration, which can cause buzzing in loose sections of the wall, depending on the character of the wall and related components.

Step 1: Cut the Hole

For sheetrock walls, cut out the hole by tracing the cardboard template

(See Figure 4). If the wire has been pre-installed, pull the wiring through the cutout hole.

Step 2: 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.

Figure 4:

Cutting Hole

Figure 5:

Tighten with Screwdriver

INSTALLATION NOTE: CONNECTOR 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 4 inside the speaker.)

Pins 1 and 4 are used as daisy-chain connections to other loudspeakers.

Installation and Wiring

INSTALLATION NOTE: CONNECTOR WIRING GUIDELINES

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 6.

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 7.

Step 3: Mount the Speaker Into the Wall

Push the speaker into the hole until the front baffle rim is flush with the wall. Tighten the mounting tabs by turning the screw clockwise until the speaker is secure. Please note that the first clockwise quarterturn rotates the attachment tabs outward. The remaining turns tighten the tabs down onto the back of the wall (see Figure 10).

INSTALLATION NOTE: MOUNTING TABS

For each attachment screw, first turn one halfturn counterclockwise to release the mounting tab from its guide.

Step 4: Adjust Tap Selector

The tap selector switch is located on the front baffle. Adjust the speak er 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.

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 5: 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 12). 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.

Appendix A - Painting the Speaker

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 mounting into the wall.

Painting Process

Clean the rim and grille with mineral spirits or other light solvent. Do not use harsh solvents 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 13. 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 wall after installation, insert a plastic or cardboard paint shield into the front of the speaker to mask the drivers and internal baffle, paint the speaker, then remove the shield.

Problem

No Output

Questionable or Intermittent

Output such as

Crackling

Possible Causes

Amplifier

Speaker Cable(s)

Faulty Connection

Action

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, mak ing 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.

Replace the cable(s) connecting the loudspeaker system and amplifier.

Check all cabling for proper connector contact. A bad connection can result in intermittent contact or dramatically increased resistance, which in turn can cause reduced output or noises unrelated to the signal.

Constant Noise such as Buzzing, Hissing, or

Humming

Improper Power Tap

Setting

A Faulty Electronic

Device in the Signal

Chain

Check the power tap setting under the speaker grille to ensure the setting is appropriate for the installation and amplifier chosen.

Since 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-

Frequncy

Output

Out-of-Polarity

Hookup Between

Multiple Speakers

When two speakers are hooked up out of polarity (out of phase), the low frequencies cancel each other out. Try reversing the polarity of one of the speakers either by turning around a dual-banana plug at the amplifier or by reversing the tip/sleeve leads on the jack.

Whichever condition results in greater lowfrequency output is the in-polarity condition.

If none of the suggestions above solves your problem, contact your nearest EV service center or EV distributor.
