Chapter 8 - Appendices

8.1 Inspections and Maintenance

8.1.1 PERIODIC PHYSICAL INSPECTIONS

Complete and thorough inspections should be done on a routine,

periodic basis. The interval between inspections and scope of the

inspections will depend on the conditions of use. This interval must

not exceed 1 year.

All mountings and enclosures should be visually examined for any

condition that may affect mounting integrity. A complete inspection

should include, but not be limited to, looking for these types of

damage to DSA Series loudspeakers and parts:

bends

breaks

broken parts

corrosion

cracks

cracks in welded joints

deformation

DANGER: Should any of the above listed types of damage exist,

immediately remove the affected part from service for repair or

replacement. If there is any question about the integrity or capability

of any mounting or rigging part to perform its intended function, it

must be immediately removed from service for repair or replacement.

8.1.2 PERFORMANCE TESTING

Listening tests and/or formal measurements should be done

periodically. The interval between such tests will depend on the

frequency of system usage and the conditions of use. All transducers

should be tested for functionality and proper performance.

Careful listening will usually reveal transducer and/or enclosure

problems in the form of distortion, buzzes, rattles, or non-function.

8.1.3 CLEANING

The sides and rear of the enclosure function as a heat sink for the

internal amplifiers. Because of this, they must remain relatively free of

dust and dirt to ensure good heat transfer to the surrounding air. If

these surfaces need cleaning, use a vacuum and/or damp cloth to

remove any dust or dirt.

CAUTION: To avoid damaging the exterior finishes do not use cleaning

solvents or abrasives.
