When using a IRS2092 based class d amp in BTL, the 2 inputs are 180° out of phase. If I use 2 IRS2092 amps, using a 90° phase shifter on the inputs, what would the output phase be for the 2 amps? I'm trying to understand what the phase shift does to the output when the inputs are already 180° out of phase.

Be kind, I'm a slow learner :D
