3.2 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 both
the immediate environment (e.g. an enclosed rack, direct sunlight) and
that 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 cannot be achieved, a forced ventilation system
has to be used.
3.3 Wiring
3.3.1 Analog Input - XLR Connection
XLR: Pin 1 = Ground (or lifted via 15 Ω resistor)
Pin 2 = Hot (in-phase)
Pin 3 = Cold (out of phase)
Always use symmetrically (balanced) shielded cable to connect the ampli-
fier.
3.3.2 Dual Channel Operation
Two fully independent amplifier channels (normal operating mode).
3.3.3 Parallel Mono Operation
Parallel operation of the two channels together.
The output terminals of the two channels are configured in parallel using an
internal relay. The (single) load is connected either to the output of channel
A or to that of channel B (as if in dual channel). While the total output of the
amplifier remains the same and the output voltage level is also the same as
in dual channel operation, the minimum impedance that can be connected
is reduced by half due to the fact that current capability is doubled. Only
channel A-Input is active. The channel B-Input is inactive – turn the volume
on channel B down to zero. This mode is useful when for example 3 identi-
cal loudspeakers are to be operated with the same power.
