The signal sources should only be connected to the balanced XLR connectors of
Channel 1 and Channel 3.
For more information about how the loudspeakers should be connected in bridge
mode, refer to the “Output Connections” section of this user manual.
3) Parallel Mode:
In parallel mode (Right position of the switch), the amplifier is configured in a way
that only the signal applied to the XLR input connector of Channel 1 and Channel
3 will be used, and will be amplified by all four output channels. (input channel 1
through output channels one and two, and input channel three through output
channels three and four)
The output level of both channels can be individually controlled by means of the
rotary controls on front of the amplifier.
