Bridge Mono: the signal of both inputs is combined,
and fed through the bridge mono outputs at twice
the power. The channel 2 gain control should be set
to a minimum, and a rated load must be used for the
higher output power. To set bridge mono mode, DIP
switches 4, 5, 6, and 7 should all be set to the right.
The loading of the speaker in bridge mono mode
should be above 4 ohms. Always use the channel
1 VR to achieve the desired gain, and leave the
channel 2 VR at the minimum level.
Please consult setup diagrams for correct speaker
conguration.
