Is it possible to bridge 2 LM3886 mono boards by using a minidsp to send an inverted signal to one board and non inverted to the other without additional modification to the boards?
Yes -- but it seems a waste of a miniusb (unless you have channels to spare). could do the same with a simple inverter circuit (one op amp, two resistors plus whatever you need to power it up...) YMMV My 2 cents.
