3.8 Wiring
3.8.1 E.U.I. and XLR Connection
XLR: Pin 1 = Ground (or lifted via 15 Ω resistor)
Pin 2 = Hot (inphase)
Pin 3 = Cold (out of phase)
Always use symmetrical (balanced) shielded cable to connect the amplifier
3.8.2 Stereo Operation
Two fully independent amplifier channels (normal operating mode).
3.8.3 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 stereo). While the total output
of the amplifier remains the same and the output voltage level is also the
same as in stereo operation, the minimum impedance that can be con-
nected 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 exam-
ple, 3 identical loudspeakers are to be operated with the same power.
