4.1.4 Mono Bridge Operation
One-channel mono bridged operation.
The second amplifier 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 (see
below). While the total output of the amplifier remains the same, both the
available output voltage and the minimum impedance that can be con-
nected are doubled, as compared with stereo ope ration. Only channel A-
Input is active. A signal feeding channel B will have no effect on the output.
Turn the volume of channel B down to zero.
To connect loudspeakers in Mono Bridge always attach the loudspeaker
between:
Pin 1+ and 2- on the upper SPEAKON
® or
Pin 2+ and 1- on the lower SPEAKON ® connectors
See also chapter 3.4.2!
WARNING !
In Mono Bridge mode RMS output voltages are as high as 125 V. Wir-
ing to the speaker loads must conform to NEC Class 2 safety stand-
ards or its equivalent that meets all national and local electric codes.
All customer specific cables may only be manufactured by qualified
suppliers/personnel. All cabling or rewiring work must be carried out
by qualified personnel.
4.2 Indicators
4.2.1 On LEDs
Under normal operation, after the amp has started, the green power LEDs
are permanently lit.
4.2.2 Signal/Protect LEDs (multifunctional)
The green Signal LEDs are illuminated when the voltage level at the output
reaches approx. 4 V; this corresponds to a power of approx. 4 W into a 4
Ohm load. The channel signal LEDs are illuminated red when the amplifier
is in Protect Mode (Mute), for example because of persistent DC-voltage
at the outputs or overheating.
