11.2. PERIODIC CHECKS
More in-depth checks will carried out to identify
the causes of possible problems that could occur
through time, and all the parameters that are difficult
to measure or not completely measurable in day-to-
day checks. It is therefore necessary to give priority to
the following checks on:
• cables, connectors’ compliance, relative wir-
ing, no cuts, tears, cabling safety, etc...;
• amplifiers (for which the relative documenta-
tion must be referred to);
• switchboards, electrical distro panels, cabling
panels and auxiliary components;
• enclosures’ impedances (e.g. using the X8 am-
plifiers’ Live Impedance function);
• frequency response of the electroacoustic ele-
ments (using a measurement microphone and
analysis software that enables to measure the
enclosures’ frequency response, which must
be compared with the reference curves);
• other electroacoustic components (check that
there is no vibration, that the panels are in
good condition, etc...);
• each element’s hardware (perfect conditions
and presence of all the components, no defor-
mation, cracks or ovalization, search for signs
of damage);
• external hardware/mechanism (rigging frame,
rigging accessories, motors, etc.);
• accessory elements (trolleys, flight cases,
trunks, etc.).
The objective of these checks is to have a system
ready for use in a perfect safe manner at any time.
The result of these inspections/tests must be report-
ed in printed/written or electronic format, in a table
such as that in the appendix.
If defects are found, the appropriate repair work
must be carried out. This must be done by special-
ized staff, with care and attention, ensuring that the
device’s operation and safety are not compromised.
In the event of any doubts, it is indispensable to con-
tact the Outline representative or distributor or Out-
line itself.
