I am currently making a Class D amplifier. Four channels powered by + -92 volts. The power supply is toroidal transformer with 40,000uF per rail ( 80 000 for all PSU ) .
Since I don't want to use relays in the output, do you think it is dangerous for the speakers if these capacitors are discharged through the speakers?
The DC protection at the output will stop the power supply to the transformer ....

The class d IC should take care of all that.
It will continue running until it sees power down then shut off both mosfets.
I got caught out with an IRS2092 amp that on power down gave out a siren noise for a couple of seconds then a massive thump through the speaker.
I got in touch with IR and they said I had too much smoothing and it was upsetting the 2092. So I added a reset circuit that held 2092 in reset if VCC dropped below 10 volts.
That fixed the problem.
