Horizontal Suspension
The loudspeaker can also hang horizontally, facing down (Figure 13). Install two
M6 eyebolts into the holes at each end of the rear panel. The loudspeaker comes
with one clear finish eyebolt; additional eyebolts are available from QSC Technical
Services Group: QSC part # HW-000323-01.
Each suspension line and the structural member it is attached to must be rated
adequately in accordance with local codes. Consult a structural engineer for
guidance.

Power and Dispersion Selection
Use the selector switch in the input cup to either select the desired power for the loudspeaker or bypass the transformer altogether and directly connect the
loudspeaker as a low impedance load. The switch is labeled for both 70 and 100-volt lines.
The AD-S162T (Figure 14) offers a choice of the loudspeaker’s dispersion. The default setting is wide; the other selection is narrow, which is suitable for highly
reverberant environments.
After you have completed the power and dispersion selection, install the weather cover, if necessary.
WARNING
Read and follow these instructions carefully. If the loudspeakers are not suspended
properly they could fall, causing personal injury and damage.
Rules for Suspension
• Consult a professional mechanical or structural engineer—who is licensed in the
jurisdiction of the sound system installation—to review, verify, and approve all
attachments to the building or structure.
• Employ the services of a professional rigger for hoisting, positioning, and attaching the
equipment to the supporting structure.
• Use all suspension hardware and components correctly.
• Before installing equipment, always calculate the suspended loads and make sure
they do not exceed the limits of any suspension components and hardware.
• Consult local codes and regulations that govern the facility that you install the
equipment in and comply with all their requirements for suspended loads.
• Use only the appropriate M6 eyebolts for suspending the loudspeaker.
• Be absolutely certain of the integrity of any structural member intended to support
suspended loads. Structural members can have hidden structural weakness.
• Never assume anything! Owner- or third-party-supplied suspension attachment points
might not be adequate for suspending the loads.
• Before lifting, always inspect all components (enclosures, suspension brackets, pins,
frames, bolts, nuts, slings, shackles, etc.) for cracks, wear, deformation, and corrosion,
as well as missing, loose, or damaged parts, which could reduce the strength of the
assembly. Discard any worn, defective, or suspect parts and replace them with new
appropriately load-rated parts.
Shock Loading
Moving or stopping a load magnifies its static weight, and sudden actions will magnify the
static weight greatly. This magnification is called
shock loading
and it can be dangerous
to people and equipment. The effects of shock loading can be instantaneous but can
also be gradual, remaining undetected until the equipment becomes visibly damaged or
fails. Precautions for shock loading require careful planning, knowing the equipment's
suspension requirements, and using proper lifting practices. Shock loading on equipment
and structures occurs most often during lifting and installation, but natural forces (winds,
earthquakes, and so on) can also impose shock loads that are several times greater than
the static load. Therefore, structures and suspension equipment must always be rated at
several times the weight of the suspended equipment.
