I've got a Pioneer 'audio digital timer' in my Hifi stack. It's original
use is switching the mains supply to my cassette, tuner and minidisc
decks for autostart unattended recording. However, I've also added the
power supply for my turntable, it's preamp and the dac-in-the-box, all
wall warts.

So, to turn on all of those - i just hit the timer over ride button.
