8 CARE AND MAINTENANCE
8.1 Maintenance information
L-ACOUSTICS amplified controller are quality units and should provide years of trouble-free services when operated
under normal conditions. The only maintenance required is to clean the anti-dust cover on a regular basis (see section 8.2).
In some cases it may be necessary for authorized service personnel to clean the inside of the controller, especially after
long operation periods in very dusty or cracked-oil smoke machines environments.
Cleaning and servicing the inside of an amplified controller must be done by qualified personnel.
An amplifier that is considered to be unsafe must be labelled accordingly and stored in a safe place
to prevent this amplifier being used mistakenly.
8.2 Filter cleaning

clogged the unit will not cool as efficiently as it should and may result in reduced output power
