Turn on one thing, have another thing turn on 10 seconds later

Does anyone know how I can make a routine where a thing is actiavted and then 10 seconds later another thing is activated? I have speakers and a sound board. The sound board must be powered on first to prevent a speaker pop. Likewise, the speakers must be turned off first before the sound board. I tried a routine where I would turn on the board and then another routine that would turn on the speakers when it sees the board is on. But it happens too fast and still pops. Any ideas?

You should use CoRe rule machine to setup a piston.
