Maintenance; Safety Considerations - Genelec 4436A Operating Manual

Automatic protection circuits
The 4436 system has protection circuits
against loudspeaker driver thermal overload
and amplifier overheating. The protection
system resets automatically so the user only
has to turn the input level down to ensure
that it does not reactivate.
Driver thermal overload protection
protects the drivers from damage caused by
prolonged overdriving with excessively high
or distorted signal. If this occurs, the circuit
automatically reduces playback volume. To
avoid this, lower the listening volume if the
sound becomes harsh and distorted at high
sound pressure levels.

Maintenance

There are no user serviceable parts within
the loudspeaker. Any maintenance or repair
should only be undertaken by qualified
service personnel.
