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).
