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 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 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) terminals. 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.

Mounting

If using the loudspeaker only (no optional mount), the loudspeaker can be set on any appropriate surface. The cabinet will lean back at a slight angle when set on a flat surface.

When operated at high output levels, the cabinet can generate sufficient vibration, causing the cabinet to move or creep if set on a hard surface. Use anti-slip matting under the cabinet or self-adhesive rubber feet to keep the cabinet from creeping.

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.

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.

Optional Mounts Available

ID-8 and ID-8T IntelliDock™ Mounts (YM-8 models, see p.6)

This mount features a quick-connect/disconnect latch which provides electrical connections and a highly-adjustable balltype mount. This mount allows for all mounts and wiring to be fully installed and the loudspeakers to be placed at the last possible moment.

A security retaining screw for the latch in included, making speaker removal impossible without the correct Allen (hex) bit to remove the screw. The IntelliDock mount and its wiring feed-through bushing provide maximum weather resistance and maximum acoustic coverage range adjustment.

Ensure the mounting surface and supporting structure are appropriately strong enough to support the loudspeaker assembly and any potential vibration or seismic activity.

Attach a safety cable to the attachment point on the bottom-back of the loudspeaker. Ensure the safety cable, cable attachment technique, securing hardware, and attachment points are strong enough to support several times the weight of the loudspeaker in the event of a primary-mount failure.

The ID-8T is identical to the ID-8, but equipped with an audio matching transformer with 70V and 100V distributed audio input capability.

Refer to the instructions included with the mount for detailed information.

Optional ID-8 and ID-8T Mounting Procedure

1- Secure the ball mount bracket to the mounting surface.

The adapter plate can be removed if desired, however, we recommend its use. Ensure the mounting surface and supporting structure are appropriately strong enough to support the loudspeaker assembly and any potential vibration or seismic activity.

2- Feed the speaker wire through the cover. Secure the cover to the ball-mount assembly.

Optional ID-8 and ID-8T Mounting Procedure (continued)

3- Choose the appropriate rubber sealing gasket and thread

the speaker wire through it. Make sure the tapered side of the gasket is toward the cover. Push the gasket into its seat, and thread the nut over the speaker wire and tighten.

4- Trim the wires to the appropriate length. Strip the wires and secure them to the terminals.

5- With the latch open, align the loudspeaker with the IntelliDock and slide the loudspeaker into place. Push the latch down until in engages with the locking tab.

6- Aim the loudspeaker in the desired direction and tighten the Allen (hex) retaining screw using the tool provided. Snug the bolt then tighten exactly 5/8 of a turn (225° rotation) to positively secure the ball- mount. If a torque wrench and appropriate hex bit are available, tighten the bolt to 16 N-m (12 lbs-ft). If extra theft deterrence is required, install the provided security screw. Attach a safety cable to the loudspeaker’s safety cable attachment point.

Optional YM-8 and YM-8T Yoke Mounts

The YM-8 and YM-8T yoke mounts provide for mounting on most any surface and are adjustable on one axis. A cover plate is provided for the loudspeaker’s rear recess and is secured with a retaining screw. The cover plate has a wiring feed-through hole, complete with rubber grommet and compression nut to prevent water from wicking down the cable and into the electrical connections.

The YM-8T yoke mount’s cover plate is equipped with an audio matching transformer with 70V and 100V distributed audio input capability.

Refer to the instructions included with the mount for detailed information.

Optional YM-8 and YM-8T Mounting Procedure

1- Secure the yoke bracket to the mounting surface. Ensure

the mounting surface and supporting structure are appropriately strong enough to support the loudspeaker assembly and any potential vibration or seismic activity.

3- Thread the speaker wiring through the cover plate.

2- Secure the loudspeaker to the yoke bracket.

4- Choose the appropriate rubber sealing gasket and thread

the speaker wire through it. Make sure the tapered side of the gasket is toward the cover. Push the gasket into its seat, and thread the nut over the speaker wire and tighten.

Optional YM-8 and YM-8T Mounting Procedure (continued)

5- Strip the speaker wiring ends and connect the wires. If

using the YM-8, connect the wires directly to the binding posts. If using the YM-8T, connect the 70V/100V terminals in the cover assembly.

5a- The YM-8T cover assembly is equipped with the 70V/ 100V matching transformer, a 4-position power selection switch, and all required connections pre-wired. Just connect the speaker wires to the appropriate terminals inside the cover, then install the cover onto the loudspeaker. Coverto-loudspeaker connections are made by the banana plugs in the YM-8T assembly.

6- Align the cover on the back of the loudspeaker and slide into place. The cover is designed to fit only one way. Install the cover retaining screw to prevent the cover from vibrating loose and to keep the connections weather-tight. Attach a safety cable to the attachment point on the bottom-back of the loudspeaker. Ensure the safety cable, cable attachment technique, securing hardware, and attachment points are strong enough to support the weight of the loudspeaker in the event of a primary-mount failure.

IMPORTANT! PLEASE READ AND ENSURE THAT THE LOUDSPEAKER IS MOUNTED PROPERLY AND A SAFETY CABLE IS INSTALLED TO RETAIN THE LOUDSPEAKER IN THE EVENT OF A MOUNTING FAILURE.

Ensure the mounting surface and supporting structure are appropriately strong enough to support the loudspeaker assembly and any potential vibration or seismic activity.
