d:24 owner‘s manual

3.2   Air flow and thermal management

The d:24 is a powerful amplifier. Due to the idle loss and the heat 

arising under heavy working conditions, it is necessary to cool the 
circuits adequately. Therefore, the amp is equipped with three fans 
with an air flow direction “front-to-rear“. 

For adequate cooling, it is mandatory to ensure an unrestricted air-

flow of the cooling system. When installing the amplifier in a rack, 

it is important that fresh/cool air can enter the front panel of the 

amplifier and warm air can be exhausted from the rear.

(

NOTE

: Never attempt to reverse the airflow in any case!)

Never block the ventilation louvers of the d:24! Without sufficient cooling, the amplifier

 

will automatically enter a protection mode and shut down the power supply for the amplifier modules.
