8.6 Mains operation & resulting temperature

The power drawn from the mains network is converted into output power to feed the

connected loudspeaker systems and into heat. The difference between power consumption

and dispensed power is called power dissipation (Pd). The amount of heat resulting from

power dissipation might remain inside of a rack-shelf and needs to be diverted using

appropriate measures.

For further details refer to the mains operation & resulting temperature tables.
