Routine Maintenance
MTI MPA82000 Amplifiers are designed to give long and reliable operation and require very little
maintenance.
SAFETY NOTICE: Please note that power to the amplifier modules is ALWAYS on when the
amplifier is connected to the mains supply.
Therefore when carrying out any maintenance the
amplifier must be disconnected from the mains supply.
As with all power amplifiers it is important to ensure that the cooling vents are not blocked and that
adequate airflow is maintained through the amplifier. Periodically check that no obstructions exist
around any of the amplifier ventilation paths. This is particularly important when the amplifier is in a
rack or case.
