Read through this manual to familiarize yourself with features, applications, and precautions before you use these products. EVID Ceiling Series loudspeakers use innovative design and materials to provide premium-level performance in a f lush-mount ceiling format. [. . . ] Simply remove the existing fitting by unscrewing the two hold-down screws, exposing a 7/8-inch (22 mm) knockout hole. Make sure to always use a listed fitting in accordance with your area's building codes and regulations.

EVIDTM 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. EVIDTM 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 6: Connect an Auxiliary Support Line (Figure 18) 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 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 pushing the grille fastener into the hole in the front of the baff le (see Figure 20). Second, press the grille into place until the front of the grille is f lush with the rim of the baff le. 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. Figure 18: Attach auxiliary support line Step 7: Adjust Tap Selector (Figure 19) The tap selector switch is located on the front baff le. 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. 1 2 Figure 19: Adjust tap selector (left: C4. 2/C8. 2/C8. 2LP; right: C10. 1/C8. 2HC) 8 Figure 20: Attach the grille EVIDTM Ceiling Series Installation and Operation Manual 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 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. Also, don't use abrasives products such as sandpaper or steel wool. If you are spraying, hold the spray can at the angles shown in Figure 21. 180° 45° Baffle 180° 45° Can (do not paint) Figure 21: Spray-painting angles If you are painting the grille also, you must first remove the internal grille cloth. If the grille is rolled or brush painted, the grille may become clogged with paint and the sound quality will suffer. 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 baff le, paint the speaker, then remove the shield. EVIDTM Ceiling Series Installation and Operation Manual 9 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 EVIDTM Ceiling Series models accommodate each job, depending on how these criteria are specified. [. . . ] 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. Check the power tap setting under the speaker grille to ensure the setting is appropriate for the installation and amplifier chosen. Improper power tap setting Constant noise A faulty electronic such as buzzing, device in the hissing, or signal chain humming Poor system grounding Since 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. Poor lowfrequency 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 low-frequency output is the in-polarity condition. If none of the suggestions below solves your problem, contact your nearest EV© service center or EV distributor. 12 EVIDTM Ceiling Series Installation and Operation Manual Appendix D -- Warranty Uniform Limited Warranty Electro-Voice® speakers and speaker systems are guaranteed against malfunction due to defects in materials or workmanship for a period of five (5) years from the date of original purchase.
