****** Page 10 ****** 10 4 en I Installation and Wiring Installation and Wiring EVID Ceiling Speaker Systems 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 4.1: 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. 2018.091 11 1 F.01U.177.705 Installation manual Electro-Voice

****** Page 11 ****** EVID Ceiling Speaker Systems Figure 4.2: RPK mounting system INSTALLATION NOTE: CONTROLLING VIBRATION Installation and Wiring I en 11 4.1 4.2 Electro-Voice 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 4.3: 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 the illustration. 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. Figure 4.4: Secure rails to C-Ring Installation manual 2018.091 11 1 F.01U.177.705

****** Page 12 ****** 12 4.3 en I Installation and Wiring INSTALLATION NOTE: TILE RAILS AND C-RING EVID Ceiling Speaker Systems 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 1— Attach Wiring to the Terminal Connector Insert the bare end of wire into the appropriate connector terminals and screw down the hold- down screw until tight, using a small screwdriver. INSTALLATION NOTE: CONNECTOR Figure 4.5: Tighten with screwdriver WIRING GUIDELINES The input connector’s four 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. There are two possible layouts for wiring a group of speakers; wiring in parallel or Daisy- Chaining. 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. 2018.091 11 1 F.01U.177.705 Installation manual Electro-Voice

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. 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. Installation manual 2018.091 11 1 F.01U.177.705 ****** Page 18 ****** 18 en I Installation and Wiring EVID Ceiling Speaker Systems 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. 1 2 Figure 4.17: Attach the grille 2018.091 11 1 F.01U.177.705 Installation manual Electro-Voice ****** Page 19 ****** EVID Ceiling Speaker Systems Troubleshooting I en 19 5 Problem No output Questionable or intermittent output, such as crackling Constant noise such as buzzing, hissing, or humming Troubleshooting Possible Causes Amplifier Loudspeaker cables(s) Faulty connection Improper power tap setting A faulty electronic device in the signal chain Poor system grounding Poor low-frequency Out-of-polarity Action 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. Replace the cable(s) connecting the loudspeaker system and amplifier. 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. Verify the power tap setting under the loudspeaker grille is appropriate for the installation and amplifier chosen. Loudspeakers cannot generate these sounds by themselves; you may have a faulty electronic device in the signal chain. Check and correct the system grounding, as required. When two loudspeakers are hooked up out of polarity (out of phase), the low frequencies cancel each other out. Try reversing the polarity of one 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. output Electro-Voice hookup between multiple loudspeakers If these suggestions do not solve your problem, contact your nearest Electro-Voice dealer or Electro-Voice distributor.

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 ceiling. 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 the illustration. 450 Baffle Figure 7.1: Spray-painting angles 1800 1800 450 Can (do not paint) 7.2 7.2.1 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 ceiling 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, and then remove the shield. Do not paint the steel back can. Appendix B System Design Guide Selecting and Positioning Ceiling Loudspeakers Several key criteria determine the type and quantity of ceiling speakers to employ in a job. Specific EVID Ceiling Series models accommodate each job, depending on how these criteria are specified. Room size Coverage density desired Coverage angle specification of the speaker Ceiling height Audio program material being played 2018.091 11 1 F.01U.177.705 Installation manual Electro-Voice ****** Page 25 ****** EVID Ceiling Speaker Systems The information below, and the free design program downloadable from Appendices I en 25 electrovoice.com, will help you optimize your EVID design. In the traditional approach to overhead distributed systems, loudspeakers are placed in a grid whose dimensions are dictated by the room height and the directivity of the speaker elements. Two basic placement patterns prevail: square spacing and hexagonal (or crisscross) spacing. Grid Edge-to-edge Minimum overlap 3 o Figure 7.2: Coverage patterns Center-to- center 7.202 Electro-Voice In addition to the spacing pattern, the designer must choose between three coverage density types, designated respectively as edge-to-edge, minimum overlap and center-to-center. The greater the overlap, the more uniform the coverage. The , page 26 illustration shows these various layout patterns. Ceiling Systems: Size vs. Coverage In the past, system designers usually specified 8-inch cone loudspeakers for distributed overhead systems, at least in part because they represented the traditional choice. EVID systems, however, allow for far more flexible options. In many cases, you can achieve excellent results at a significant savings — by using a-inch transducers. This is especially true in jobs that do not require extended low-end response or high SPL levels. Four-inch transducers, such as those used in the C4.2, offer wider dispersion to allow for fewer speakers to be employed in the job. For example, due to its smaller cone diameter, the C4.2 exhibits significantly wider dispersion (130 degrees) than the C8.2 (110 degrees) at the -6 dB points. The effect of this characteristic on an overhead system is indicated in the , page 26 illustration. In replacement applications where existing speaker positions are used, the C4.2 (shown in angle A) offers greater overlap and, thus, more uniform coverage than an older conventional 8-inch unit (shown in angle B). When specifying a new system, you can take advantage of the C4.2's wider dispersion to decrease the number of speakers required to cover a given area. This will result in even greater savings. Installation manual 2018.091 11 1 F.01U.177.705 ****** Page 26 ****** 26 en I Appendices Ceiling Figure 7.3: Size vs coverage EVID Ceiling Speaker Systems Of course, the C4.2 is somewhat less sensitive than the 8-inch C8.2. The difference is – 5 dB. The C4.2 will also have slightly reduced low-frequency capabilities below 65 Hz. However, neither of these factors is a significant problem in many distributed systems. The C4.2 is conservatively rated to handle 80 watts of continuous power equal to or greater than most other brands of 8-inch units, so its continuous SPL output will be more than adequate. Moreover, its low-frequency output can easily be augmented with the addition of the CIO.I subwoofer. For these reasons, the C4.2 represents a great way for you to provide good audio coverage while maintaining a competitive edge in price quotes in installations that do not need the extended performance of the larger models. Reverberant Rooms and High Ceilings Situations arise, however, in which controlled coverage is more desirable than broad dispersion. Very large live spaces such as gymnasiums, convention centers, shopping mall atriums, and the like all benefit from more controlled sound projection. In such installations, the EVID C8.2HC is the best choice. Its 75-degree coverage pattern above 1 kHz provides more intelligibility in large, acoustically live spaces. It also has a high 93 dB sensitivity rating for optimum efficiency. SPL Requirements: How Loud? The EVID C8.2 is a great speaker to use when higher SPL is required. The fidelity and bandwidth of the unit is substantial and is ideal for applications requiring high quality foreground music reproduction. The C8.2 has substantial low frequency energy down below 60 Hz. This is more than sufficient for most applications. Layout: How Many? The Coverage Diameter by Ceiling Height chart shows the effective coverage diameter of the EVID models assuming a a-foot listening plane height. Using these figures you can lay out a coverage pattern for the job after deciding the overlap criteria.

It is important to note that the CIO.I subwoofer depends on the ceiling and walls to properly load itself and to reinforce its bass output. Correct positioning is important to get maximum impact. In smaller rooms when a single CIO.I is used, a center or near-center position is best. This gives the most even coverage. For larger rooms where more than one CIO.I are employed, the added effect of the room's walls can be used. In such a space, position the subwoofers evenly throughout the room and a few feet from the wall or corners. The added loading of the walls will enhance the response in these larger areas.
