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.

VORTEX

A

Z ≥ 2*Zmin

B

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 amplifier 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 specific cables may only be manufactured by qualified suppliers/personnel. All cabeling or rewiring work must be carried out by qualified personnel.

*Zmin = 2 Ω for VORTEX 6, 4 and 2.6 *Zmin = 4 Ω for VORTEX 200V

3.9.5 SPEAKON Connection

Both SPEAKON connectors are connected to channel A and channel B outputs.

The pin configuration 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-
