Having put a chip preamp upstream of my comertial power amp and a volume pot in front of the lot. I now get a huge startup thump. I didn't get it from running the commertial amp standalone, so the problem lies in the preamp which runs from its own 12V switch mode PSU.
Is there a very low power soft start circuit which doesn't require a relay?
I also didn't get so much when the volume pot was between the 2 amps. Have I just answered my own question?
