3.4 Cooling
Under normal operation of the power amp, overheating should never be a problem. The air is taken in from the front and out through the back, it is of course essential that while the power amp is running air is able to circulate around it freely.
The efficiency of the cooling will depend on the immediate environment (e.g. an enclosed rack, direct sunlight). If the amp is installed in a case, the open area at the back of the case must be at least 140 cm².This area should be in line with the amp.
If this can not be achieved a forced ventilation system has to be used.
3.5 Ground Lift
The input signal ground (pin 1 for all 4 XLRs) is connected to the ground of the mains supply. In order to avoid ground loops, this connection can be separated via a resistor. The ground potential of the power amp and the ground of the loudspeaker always remain connected to the ground of the mains supply regardless of the setting of this switch.
