CAMCO USER MANUAL
VORTEX POWER AMP SERIES
P.14
3.6.5 Stereo Operation
Two fully independent amplier channels (normal operating mode).
3.6.6 Bridge-Mono 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-
er remains the same, both the available output voltage and the minimum
impedance that can be connected are doubled, as compared with stereo oper-
ation. Only Channel A-Input is active. A signal feeding Channel B will have no
effect on the output.
WARNING!
RMS output voltages as high as 230 V are available at the output.
Wiring to the speaker loads must conform to NEC Class 3 safety standards.
3.6.7 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 1
or to that of channel 2 (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. This mode is useful when powering 3 speaker cabinets in parallel. A load
balancing is achieved in this case.
NOTE: For parallel mono operation, to prevent damage of one SPEAKON
connector and to reduce loss of power because of contact or cable
resistance, it is highly recommended to wire speaker loads using
both 2 channel SPEAKON connectors with all contacts connected.
