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 prob-
lem. The air is taken in from the front and out through the back. It is essential
that while the amplifier is running the 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 40 cm². This area should be in line with
the amplifier.
If this cannot be achieved a forced ventilation system has to be used.
3.5 Ground Lift
The input signal ground (pin for all 4 XLRs) is connected to the ground of
the mains supply. In order to avoid ground loops, this connection can be sepa-
rated 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.
