Ventilation (for all models)
The airflow direction is side-to-rear. In general, setting up or mounting the power amplifier
has to be done in a way that fresh air can enter unhindered at the side and exhausted air
can exit at the rear. When installing the power amp in a case or rack system, attention
should be paid to these details to provide sufficient ventilation.

Caution!
Blocking/closing the power amp's ventilation louvers is not permissible. Without sufficient
!
cooling/ventilation, the power amplifier may enter protect mode.
Keep ventilation louvers free from dust to ensure unhindered airflow.
Notice!
i
Do not use the power amplifier in direct sunlight or near heat sources, like heater blowers,
stoves, or any other heat radiating devices.

Allow for an air duct of at least 60 mm between the rear panel of the power amplifier
and the inner wall of the cabinet/rack case.
Make sure that the duct reaches up to the cabinets or the rack case's top ventilation
louvers.
Leave room of at least 100 mm above the cabinet/rack case for ventilation. Since
temperatures inside of the cabinet/rack case can easily rise up to 40 °C during
operation of the power amp, it is mandatory to bear in mind the maximum allowable
ambient temperature for all other appliances installed in the same cabinet/rack case.
