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.
Grill Removal If it is necessary to remove the protective grill, do so with care as to avoid bending or distorting the grill. 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.
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.
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 bushing nut, bushing, cover, and gasket before making connections.The input wiring cover is keyed to fit one way only! Be sure the keyed end is oriented toward the bottom of the loudspeaker cabinet. For proper sealing, we recommend #12 to #10 AWG (3.3 to 5.3mm2) stranded loudspeaker cable with a flat or twisted cross section.
Connection I-282H PASSIVE: Set the BI-AMP / PASSIVE selector switch to PASSIVE. Connect the full-range + input signal to Speakon pin 1+ and the full range input signal to Speakon pin 1-. The two Speakon connectors wired in parallel, allowing a second I-282H loudspeaker (also set for PASSIVE operation) to be connected directly to the remaining Speakon connector. I-282H Speakon pinout ACTIVE: Set the BI-AMP / PASSIVE selector switch to BI-AMP.

Painting the Loudspeaker The loudspeaker enclosure, grill, and mount can be painted to match any decor, provided the following precautions are observed. The cabinet is made of high impact polystyrene which requires controlled painting procedures in order to obtain good results. Use a paint “system” designed for high impact polystyrene from any reputable paint supplier. 1- Remove the grill. 2- If painting mount and loudspeaker as a unit: Attach the ball mount or yoke mount.
