"QSC" and the QSC logo are registered with the U.S. Patent and Trademark Office 2 Speakon® is a registered trademark of Neutrik AG, OmniMount® is a registered trademark of OmniMount Systems, Phoenix, AZ, USA Introduction Thank you and congratulations on your purchase of the I-282H, AD-S282H, or AD-S282HT multi-use, weather resistant loudspeakers. These products represent the state-of-the-art in lightweight sound reinforcement loudspeaker systems. To get the most from your investment, we encourage you to review this manual carefully. These loudspeaker systems are full range, high output, two-way designs delivering superior sound quality and high SPL in a weather resistant enclosure. The low frequency drivers feature neodymium magnets, while the high frequency driver features a ferrite magnet. The included yoke mount provides secure and versatile installation. These loudspeakers make an excellent choice for a wide variety of applications. All models include an adapter plate for users who desire to use OmniMount®'s suitable loudspeaker mounting options. The I-282H features two Speakon® connectors wired in parallel for fast, reliable connection and easy parallel connection of multiple loudspeakers. The Speakon connectors are wired for passive or bi-amp use and have a selector switch for bypassing the crossover when used in bi-amp applications. Additionally, the I-282H includes two swivel "outrigger" feet for converting the yoke mount to a floor monitor application. The AD-S282H and AD-S282HT models feature weather resistant input wiring covers and wiring strain relief bushings. They also include socket head screws for applications where enhanced mounting security may be desired (used in place of the yoke mount retaining knobs). The AD-S282H model is bi-amp capable and features a crossover bypass switch. The AD-S282HT is 70V/100V matching transformer equipped complete with an integral power-tap selector switch. The transformer may be bypassed for low impedance (8 ohm) application versatility. Two sets of parallel-connected input wiring barrier-strip terminals are provided for connecting multiple loudspeakers.

The grill is held in place by two retaining screws, one at the front edge of the top of the cabinet and one at the front edge of the bottom. Removing the Grill 1- Using a #2 Phillips-head screwdriver, remove the two grill retaining screws. 2- Carefully pry the grill from its retaining groove using a plastic flat-blade tool such as a plastic putty knife. Gently and evenly work the grill out of its retaining groove to avoid bending the grill. Coverage Angles Before mounting the loudspeaker, determine the mounting orientation and desired coverage angles. As supplied from the factory, the loudspeaker's coverage angles are 90° (horizontal) x 60° (vertical) with the cabinet oriented vertically. The waveguide can be rotated to interchange the coverage angles. Rotating the Waveguide to Alter HF Coverage Pattern 1- Remove the grill as outlined, above. 2- Remove the eight waveguide retaining screws. A #2-size Phillips screwdriver is recommended. 3- Reach into the waveguide's port and pull gently to remove the waveguide. Be careful not to damage the connections, wiring, or the gasket between the waveguide and the cabinet. 4- Rotate the horn 90° clockwise or counter clockwise and set it back in place. Make certain the wiring is not stressed or pulled loose from its connections. 5- Before reinstalling the waveguide screws, lift the assembly a small distance and make sure that the gasket is properly in place. Reposition it, if required. Set the waveguide in place and reinstall the screws. Do not overtighten. 6- Replace the grill and install the upper and lower grill retaining screws. 4 Mounting IMPORTANT! ENSURE THAT THE LOUDSPEAKER IS MOUNTED PROPERLY AND A SAFETY CABLE IS INSTALLED TO RETAIN THE LOUDSPEAKER IN THE EVENT OF A MOUNTING FAILURE. CONSULT A LICENSED, PROFESSIONAL ENGINEER WHEN ANY DOUBT OR QUESTIONS ARISE REGARDING A PHYSICAL EQUIPMENT INSTALLATION. Attach safety cable here Safety Cable Attachment (all models) On the back of the loudspeaker, near the bottom, is a safety cable attachment point. Install a safety cable strong enough to support several times the weight of the loudspeaker assembly in the event it may fall. The cable must be secured to a secondary support point which is also strong enough to support several times the loudspeaker's weight. Yoke Mount (all models) The included yoke mount handles most surface mounting applications. It is constructed of light, strong alloy and pre-drilled for ease of use. Integral bushings at the cabinet contact points ensure ease of positioning. A large center-hole is provided on the mounting surface side for wiring pass-through. Mount the yoke to a surface strong enough to support the weight of the loudspeaker assembly using suitable hardware (not included). If any doubt exists as to the suitability or strength of the mounting surface, consult a qualified professional engineer. After securing the yoke to the mounting surface, have an assistant hold the loudspeaker in place while installing either the retaining knobs or socket head screws with flat and lock washers (AD-S282H and AD-S282HT only). Once the loudspeaker has been positioned for desired acoustic coverage, tighten the hardware securely. For enhanced security, use the included M10 socket head screws to secure the loudspeaker to the yoke mount. Floor Monitor (I-282H only) The I-282H yoke mount comes with two swivel feet, four self-adhesive rubber feet, and retaining knobs. Attach the two of the rubber feet to each of the two swivel outrigger bars, one at each end. Press firmly in place to ensure adhesion. Then attach each of the two swivel outrigger bars to the yoke mount using the two small retaining knobs included. The rubber feet should be oriented away from the yoke mount. Swivel the outrigger bars perpendicular to the long axis of the yoke and tighten the retaining knobs. Set the completed yoke assembly on the floor, resting on the rubber feet. Place the loudspeaker into the yoke and secure using the two large retaining knobs provided. Position the loudspeaker for desire acoustic coverage and tighten the retaining knobs securely. Pole Mounting (I-282H only) On the bottom of the I-282H is a pole cup that accepts 1.375" or 1.500" (35 mm or 38 mm) pole diameters. For pole mounting, lift the loudspeaker into position over the pole end and set it onto the pole. Ensure the pole is fully and firmly seated into the pole cup of the loudspeaker. OmniMount (all models) For applications requiring the use of OmniMount's Pro 60.0 mount, there is an adapter plate included. The adapter plate is used between the OmniMount bracket and the loudspeaker cabinet. Orient the plate with it's curved side toward the loudspeaker and its safety cable access cut-out toward the bottom of the loudspeaker. Attach to cabinet using the provided M4 x 18mm self-tapping screw. Consult OmniMount's literature and installation recommendations for proper and safe application of their product. We recommend the use of M8 x 1.25 x 50mm bolts with a flat washer 1.8mm thick and a split-lock washer 1.9mm thick for securing the OmniMount bracket to the loudspeaker cabinet. OmniMount adapter plateAttach to cabinet using provided M4 x 18mm self tapping screw, then attach OmniMount following manufacturer's recommendations. 5 Input Connection Cover (AD-S282H/HT models) The loudspeaker includes a weather resistant cover for the input terminals. If using the cover, be sure to pass the wiring through the bushi ...
