Inspection and preventive maintenance

How to do preventive maintenance

Inspect the system before any deployment and after any corrective maintenance operation.
Perform preventive maintenance at least once a year.
Refer to the maintenance manuals for advanced maintenance.

Rigging and hardware

Perform the

Rigging part inspection

(p.42) on each rigging part.

Use the

Mechanical system overview

(p.42) to identify critical parts of the system and apply the specic checks

described in the

Inspection references

(p.50).

Do the

Rigging check

(p.53).

If any parts are damaged, contact your L-Acoustics representative for further instructions.

Acoustics

Perform the

Enclosure check

(p.57).

Perform the

Listening test

(p.59) to detect any degradation in sound quality.
