Why did twoleftears dog run out of the room when it was turned on??
Anyone stating class D is "noisy as hell" very obviously doesn’t know what the heck they’re talking about.
Go near one with a portable am radio tuned off station around 600khz (or whatever your switching frequency is) and see what you get out of the radio.
If you look at their output on a oscilloscope they are more than just noisy as heck! And that (undetectable to human) noise goes through to the tweeter if it’s not Zobel’ed as many hi-end ones aren’t
Take the output filter off the output and they are an abomination of noise that the military could almost use as a mind altering stun weapon.
Not noisy at all. sure Cheers George
