Hey,
I am trying to control the output volume from a 70V constant voltage audio system using a digital pot but I cannot find a pot that I think will work for such high voltage.
I also don't really understand the 70V constant voltage speaker system signals. Is the output 0V-70V? Is the output differential around 35V or 0V? If anyone has a graph of what the output looks like that would be amazing.
I'm pretty sure the output of my audio amplifier will not go beyond 10W but if possible, I would like to find a digital pot that can handle up to 35W. Do digital pots exist for such high power or is there a way to setup a normal digi pot to handle the signal but still allow for a full range of volume control?
If possible, I would like to use SPI to control the pot.
Thanks in advance.
