USER MANUAL
VORTEX 6, 4, 2.6 and 200V P.15
mode is useful when, for example, 3 identical loudspeakers are to be operated
with the same power.
3.9.4 Mono-Bridge Operation
One-channel mono bridged operation.
The second channel processes the same input signal, but with reversed phase.
The (single) load is connected between the two positive channel outputs using
a suitable connected SPEAKON connector. While the total output of the ampli fi er
remains the same, both the available output voltage and the minimum impedance
that can be connected are doubled, as compared with stereo operation. Only
channel A-Input is active – turn the volume on channel B down to zero.
WARNING !
In Mono-Bridge mode RMS output voltages are as high as 230 V. Wiring
to the speaker loads must conform to NEC Class 3 safety standards or its
equivalent that meets all national and local electric codes.
All customer specifi c cables may only be manufactured by qualifi ed
suppliers/personnel. All cabeling or rewiring work must be carried out by
qualifi ed personnel.

3.9.5 SPEAKON Connection
Both SPEAKON connectors are connected to channel A and channel B outputs.
The pin confi guration of the SPEAKON-connectors is as follows:
Upper SPEAKON: Pin 1+ Channel A signal
Pin 1- Channel A ground
Pin 2+ Channel B signal
Pin 2- Channel B ground
Bottom SPEAKON: Pin 1+ Channel B signal
Pin 1- Channel B ground
Pin 2+ Channel A signal
Pin 2- Channel A ground
