3.3 Mounting
Use four screws and washers when mounting the amplifier to the front rack rails.
For mobile use, the amplifier should also be secured using the 9” mounting
elements on the rear panel.
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 temperature of the cooling air will depend on the immediate environment
(e.g. an enclosed rack, direct sunlight) and on whether the front filter is clogged.
If the amp is installed in a case, the open area at the back of the case must be at
least 40 cm². This area should be in line with the amp.
If this can not be achived a forced ventilation system has to be used.
3.5 Ground Lift
Pin  for all 4 XLRs is tied to the ground potential in the mains supply. Opening
the ground lift switch causes this connection to be broken. This allows ground
loops that sometimes occur in practice to be eliminated. The ground potential
of the power amp and therefore of the loudspeaker outputs is independent of
the switch setting and remains at the ground potential of the mains supply.
Removing or taping the mains connector ground is illegal and dangerous.
