P.14
3.8 Mode Selector
The switch on the rear panel changes the operating mode. Moving this switch will shutdown the amplifier 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 amplifier.

USER MANUAL
VORTEX 6, 4, 2.6 and 200V
3.9.2 Stereo Operation
Two fully independent amplifier channels (normal operating mode).

3.9.3
Parallel operation of the two channels together.
VORTEX
Zres ≥ 0,5*Zmin

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 op- eration, the minimum impedance that can be connected is reduced by half due to the fact that current capability is doubled. Only channel
