FM3 pops too and nice that FXIII has this circuit. And it seems the FM9 too ?!
With my FM9 I didn't noticed that, because I got it for 3 days and regardless of used hardware I always switch on preamp at first and then power amp.
Mixer first, then PA power-amp
Fractal first, then monitors, FRFR, poweramp with cab.
In addition my poweramp at rehearsal room has a mute switch, that is activated until I've booted up all other things or at breaks.
That's a habit automated over the years, so I didn't notice if some hardware may have such a mute circuit.
Is there any written proof that only the FX 3 has this cricuitry?
I mean even the Scarlett 18i8 a $369 interface has this
