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
ing options.

®’s suitable loudspeaker mount-

The I-282H features two Speakon
tion 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.

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. 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.

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.

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.

cable here

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.

OmniMount adapter plate­Attach to cabinet using provided M4 x 18mm
self tapping screw, then attach OmniMount
following manufacturer’s recommendations.

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.
