Hi there. I am making a DIY build with some Hypex Ncore NC500MP boards. There will be a couple of amp modules in a box with custom input PCB for signal detect auto power on, 12V trigger IO, and temperature monitoring.
I was thinking of adding some kind of soft start functionality, i.e. have the amp modules muted on turn on/off, to reduce pops and/or speaker damage. At the moment, this is done by using the amp power good signal to control the amp mute input. Is there any point in doing this if I am controlling the amp ps enable line to bring amp modules in and out of standby mode. For reference, the amp module datasheet is here: https://www.hypex.nl/media/90/08/74/1646057938/NC500MP_04xx.pdf.
If anyone has any comments, suggestions, advice, that'd be much appreciated.
