Introduction

Thank you and congratulations on your purchase of the Acoustic Design AD-S82 Multi-Use, All-Weather Loudspeakers. These products represent the state-of-the-art in all-weather, lightweight SR (sound reinforcement) loudspeaker systems. To get the most from your investment, we encourage you to review this manual carefully.

The AD-S82 loudspeaker systems are full range, high output, two-way designs delivering superior sound quality and high SPL in a lightweight, all-weather enclosure. These loudspeakers make an excellent choice for a wide variety of SR applications.

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. Gently and evenly work the grill out of its retaining groove to avoid bending the grill.

2- Remove the eight waveguide retaining screws. A #2-size Phillips screwdriver is recom- mended.

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 counterclockwise and set it back in place. Make certain the wiring is not stressed or pulled loose from its connections when rotating the assembly.

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 install the screws. Do not overtighten.

6- Replace the grill.

Connection

Connect the amplifier’s + and - outputs directly to the loudspeaker’s + (red) and - (black) termi-

nals. If using optional ID-8 or YM-8 mounting hardware, refer to the instructions provided with the hardware.

Maintain proper speaker and amplifier connection polarity throughout the entire system. All positive-marked loudspeaker terminals should be connected to positive-marked amplifier output terminals. This will provide the best possible low-frequency output from your system.
