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 effi ciency of the cooling will depend on the immediate environment (e.g.
an enclosed rack, direct sunlight) and on whether the front fi lter 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 Indicators
On the front panel there are two yellow LEDs to indicate the mode that is set.
In stereo mode none of them will be lit. In Parallel-Mono the (PM) LED will be lit
and in Mono-Bridge, the (MB) LED will be lit.
