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) 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 140 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
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.
Removing or taping the mains connector ground is illegal and dangerous.
3.6 Optional Feature
Could be activated with future released software versions.
3.7 Mode Selector
The switch on the rear panel changes the operating mode. Moving this
switch will shutdown the amplifier and restart it in the new operating mode.
