1 Ohm Capability Setting

It is possible to drive 1OHM load paralleling the outputs into a single channel.

In order to implement this feature, outputs are to be connected on the board as follows:

OUT1+ (PIN35 and PIN36) shorted to OUT2+ (PIN19 and PIN20)

OUT1- (PIN28 and PIN29) shorted to OUT2- (PIN26 and PIN27).
