CARE AND MAINTENANCE

8.1

Maintenance information

The L-ACOUSTICS ® 115XT HiQ enclosure is a technical product designed for intensive and various indoor and
outdoor sound reinforcement applications. To fulfill such demanding conditions, L-ACOUSTICS has designed 115XT
HiQ with high grade and reliable components:
• Weather-proof transducers engineered using materials with high immunity to oxidation.
• Baltic birch plywood-made cabinet.
• High resistance, non biodegradable Airnet front grill fabric.
• Screws and rigging points resistant to oxidation.
However, in order to ensure safety and product performance, it is essential to proceed to a frequent inspection of the
115XT HiQ cabinet and its internal components. The check frequency varies upon the conditions of system use and
comprises three steps (see section 8.2).

Testing procedure

a. Check of transducer and enclosure acoustic behavior. Use a sweep frequency generator with a maximum
voltage of 0.2 volts (-12 dBu, -14 dBV), connected to the active input of the LA4 amplified controller. Apply a
sweep from 50 Hz to 20 kHz: the sound should remain pure and free of any unwanted noise. If not, check the
mechanical assemblies and if necessary contact an L-ACOUSTICS authorized representative to repair damaged
components.
!
0.2 volts is a maximum value.
This can generate very high sound levels at given frequencies.
Use ear protection for operation.
WARNING
b. Check of mechanical assembly and rigging parts inspection. Inspect the general aspect of assembly and
check that screws are locked tight. Also check the integrity of rigging elements (no signs of deformation, indents,
or rust). If necessary contact an L-ACOUSTICS authorized representative to repair damaged components.
c. Check of external aspect. Check for absence of cracks on the cabinetry. Remove the dust from the front fabric
with a vacuum device.
!
If paint is applied, protect mechanical parts and do not apply paint to the front grill fabric.
This could fill the fabric holes and deteriorate the acoustic transparency of the material.
