The possible output connections, depends on the configuration of the switch MONO/
STEREO/ BRIDGE of the power amplifier:
CAUTION:
Do not change the configuration of MONO/STEREO/BRIDGE switch unless the
power amplifier is first turned off. Before turn on the power amplifier, make sure that the
mains, input and output connections are correct. If doesn't follow these recommendations,
could cause a power amplifier and/or loudspeakers breakdown.
STEREO MODE OPERATION: In this mode the two channels of the power amplifier are totally
independent, for what the two inputs signal, and the two power outputs will be wiring inde-
pendently. In order to configure the power amplifier in STEREO mode, turn the amplifier off,
slide the MONO/ STEREO/ BRIDGE switch to the center position, and wire the input and output
connections according to the next picture:
MONO MODE OPERATION: In the mode MONO, the input signal should be carried out for one
any of the XLR connectors or Jack 1/ 4" (only for MF8 and MF12) of the CHANNEL 1 (CH1). The
input signal is routed to both channels, being the power outputs totally independent. In the
models MF16 and MF24, the input attenuators could configure internally, so that the CH1
input attenuator governs both channels, or that each input attenuator affects to their corre-
sponding channel (for more information consults the section SPECIAL OPERATIONS - INPUT
ATTENUATORS CONFIGURATION IN MONO MODE), in the models MF8 MF12 the input attenu-
ators of the two channels are totally independent in MONO mode. In order to configure the
power amplifier in MONO mode, turn the amplifier off, slide MONO/ STEREO/ BRIDGE switch
toward the left (as you face the rear panel), and wire the input and output connections
according to the next picture:
