is there any way to eliminate the annoying "click" the speakers make when my sound board gets powered up.
it's an adafruit fx sound board with built in amp 2 x 2. any ideas appreciated.
The "normal" way is to have a relay switch the speaker onto the amp outputs after a start up delay. It is an Anti Thump board. http://www.redcircuits.com/Page171.htm
Here is just one example.
