Multi-effects, power and isolation: supply rail decoupling ?
Posted: 07 Mar 2012, 19:04
Now then lads,
Just had one of those lightbulb moments. Trying to cram a bunch pedals and a power supply on a shelf in my rack might not be such a brilliant plan after all. The enclosures take up a lot of room with all the space they need for batteries and footswitches, features that will be useless to me once I get everything hooked up. So instead of that, I might as well buy a rack-mountable enclosure to rehouse the effects I already have and don't bother with enclosures for the ones I still have to build.
That's all very nice, but then comes the tricky bit. Or at least, tricky to me: getting power to these effects in a way that doesn't introduce any unwanted noise. Can I get away with using a single powerful power supply and applying supply rail decoupling (100r + 100 or 220 µF ?) or should I do something else ? I could stick a Pedal Power or a different power supply unit in my rack, or buy proper loads of individual transformers to build something like the GEOfex Spyder.
thank you for your help !
