I have an audio signal from a class-d 100V and 500W. amplifier.
I want to distribute this to 16 different sets of speakers and control the volume of each set individually. I am unable to find any solution for 100V.
If volume control isn't possible I would like to be able to switch ON/OFF.Relays are one of a solution but that will be taking a lot of board space ,which is limited for my application. I was interested in this Chip, but the availability is an issue and I cant find it.
Can someone please help me to find any solution for volume control, or finding me an alternate IC or any other solution.
