9 Maintenance
The mixer amplifier has been designed to function without problems for a long time with a
minimum of maintenance.
In order to guarantee trouble-free operation, clean the unit with a damp lint free cloth,
especially the air intake holes on the front. Have a technician clean the dust from the fan and
the inside at regular intervals for the models that have a fan. Base the interval on the actual
situation and dust build up, start with an interval of at least once per year. Periodically check
the connectors for corrosion and check the screw terminals to make sure that they have not
become loosened.
