MPA82000 Power Amplifier
Dust and debris can accumulate in fan-cooled equipment over time. Therefore it is recommended that
every 2 years the amplifier is disconnected from the mains supply and the lid removed so that dust
can be carefully removed. One method is to use a high-pressure airline to blow dust from the amplifier
chassis. Care should be taken to ensure airflow is not excessive and also the airline should be clean
and dry (i.e. oiled machine tool airlines are not suitable for this operation). Safety goggles must be
worn at all times when using high-pressure air. Alternatively a vacuum cleaner and a soft paintbrush
can be used, with care, to remove built up dust within the unit.
The amplifier case can be cleaned with 3M Stainless Steel Cleaner & Polish or similar products
suitable for delicate electronic equipment. Do not spray cleaning products directly at grilles or
connectors.
Replacement of an amplifier module
Because of the simple modular layout of the MPA82000 it is very straightforward to replace an
amplifier module by following these simple steps:

amplifier casing
1. Switch off power and disconnect mains lead from supply
2. Remove 4 x 6mm screws and 4 x 4mm screws from rear panel, noting screw positions
3. Remove rear panel and disconnect power connections to modules
4. To remove a module push it backwards and slide it out
5. Slide replacement module into position
6. Reconnect all power connectors
7. Refit rear panel with 8 screws
