6. PERIODIC CONTROLS
All the components of the system (loudspeakers,
amplifiers, cables, rigging hardware etc.) require a
number of periodic controls to be performed at re-
gular time intervals to be decided by the persons in
charge.
In-depth controls must be performed ar regular
time intervals (for example, every 6 or 12 months),
after prolonged use (e.g. after a tour or a festival) or
after particular working conditions (incorrect use,
wrong rigging, drop etc.)
The aim of these checks is to guarantee the best
possible performance and safety of the system from
all points of view. Any discrepancies found must be
corrected. If these discrepancies compromise the sa-
fety of the system, it must be immediately dismissed.
The in-depth checks are aimed to discover eventual
causes of possible problems that coud occur over
time and to check the parameters that are not me-
asurable during everyday use. These checks include:
• cables, connectors’ conformity, pinouts, cuts,
tears, cables’ safety etc.;
• amplifiers and their electrical and thermic
safety (always verify the amplifier does not
overheat during prolonged use)
• frequency response check of the electroacou-
stic components (using a measurement mi-
crophone and software that can measure the
frequency response of the loudspeakers, in or-
der to compare them to the reference curves);
• control of other electroacoustic components
(absence of vibrations, integrity of the panels
and so on);
• integity check of all components, absence of
deformations, cracks and roundnesses, signs
of damage) ;
• check of all accessories (wheelboards, tripods,
poles etc.)
The aim of these checks is to have a ready-to-use
system at any time. The results of these checks must
be reported on a paper or electronic sheet like the
one at the end of this manual in the appendix.
In case of difformities it will be necessary to proceed
with reparation which must be done by skilled per-
sonnel only. In case of doubts it is mandatory to con-
tact an Outline’s representative, distributor or Oultine
headquarters directly.
