Yes, I don't need a trigger, I'm searching a way to avoid pops and clicks so, if You have tried a logic that sequences mute-power on-mute-power off without success, the only way I know is to add a speaker protection circuit that disconnects speakers before power off and reconnects it after power on. The only thing that makes me puzzled is the declaration of Rouge audio and Kjfaudio of pop free power on and off with the control logic.
I built my nc122mp with ghent audio case last week, and I planned to add a 12V trigger to use standby feature and avoid pop/click on power off.
So it seems that even with mute/standby behavior the pop remains ?
The only solution is to let the amp main spms always on ?
Have You tried with a circuit that correctly implements startup sequence or simply with switches on standby and mute pins? I've no time to test these daysI confirm.
I made some tests this morning, and use standby mode don't resolve the "plop" sound.
If the preamp is on, the plop is quieter than if the pream if off. But stills plop
