3.8 Mode Selector
The switch on the rear panel changes the operating mode. Moving this switch
will shutdown the amplier and restart it in the new operating mode.
3.9 Wiring
3.9.1 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 amplier.
3.9.2 Stereo Operation
Two fully independent amplier channels (normal operating mode).
3.9.3 Parallel-Mono Operation
Parallel operation of the two channels together.
The output terminals of the two channels are congured 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 amplier
remains the same and the output voltage level is also the same as in stereo
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
