300W 6x LM3886 bridged-paralleled power amplifier

300W 6x LM3886 bridged-paralleled power amplifier

The goal of this design is to create a audio power amplifier that can deliver 300W into my 4-ohm DIY speaker with low distortion.
The function of DRV134 is to convert the un-balanced input signal to a balanced signal, so that the non-inverted signal is fed to one PA150, and the inverted signal is fed the another PA150. One of the PA150 is connected to the speaker’s positive input, and the other PA150 is connected to the speaker’s negative input. Because of this push-pull configuration, the total gain of the amplifier is doubled. Each PA150 has a gain of 20, so the gain of the BPA300 is 40.
