Consult an experienced rigger or engineer when it comes to rig-

ging practices, methods, required materials, or other details. The

kinetic energy from a 214 lb. object falling 40 feet onto a solid surface is truly

astounding. Injury or loss of life could occur, even to those who are not in

close proximity, let alone the injuries or deaths that may result from a pan-

icked crowd. Safety is the most important part of the job! Take the extra time

to obtain the proper rigging materials and components, or keep the system on

the ground! All rigging fittings, slings, Spansets™, shackles, bolts, and other

equipment should be inspected carefully before each use. Questionable com-

ponents or materials should immediately be discarded where they won’t be

found and re-used by someone else. In particular, forged eyebolts, shackles,

pins, and other high-carbon steel components are susceptible to fracture, if

they fall even a few feet onto a hard surface like a concrete floor. Play it safe

and do not use any questionable components or materials!

(1) General

Troubleshooting the APL-10/12 is a simple process. With an integrated sys-

tem, there’s really not much that can go wrong. If a problem does arise, it

usually can be solved quickly by performing the processes described below.

All repair work that involves dismantling the APL-10/12 must be performed

by a qualified, trained service technician. The power cable must be discon-

nected before attempting any repair work. Lethal voltages are present inside

the APL-10/12 when the power cable is connected!

(2) Drivers

The APL-10 employs dual 15" high power cone drivers and the APL-12, dual

18" high power cone drivers. All are treated with Ferrofluid

™ as a dampen-

ing and heat conduction agent. Additionally, the cone surfaces are treated

with a proprietary compound that makes them highly resistant to water

damage. This compound has an important secondary purpose: the cones will

not change mass due to moisture absorption in humid weather, making the

system’s sonic qualities exceptionally stable when used in varying climactic

conditions.

Occasionally, due to mechanical shock or abusive operation, a driver may

become dysfunctional. Drivers can fail completely, or they can fail in such a

way that they continue to reproduce sound but their output becomes

noticeably distorted. The latter is usually due to deformation of the voice

coil, resulting in the coil rubbing against the gap. In either case, driver replace-

ment is warranted.
