What's the power outlet on the back of the Mark IV for?

[SonVolt]

On the back of the head there's a 3 prong electrical outlet. What's it there for? Can I plug my pedal power supply into it? Cain I plug another head into it?

Pedal power yes, another head, no. Unless your Mark IV has been modified, the outlet is rated for 200 watts. Although the Mark IV's output power is rated at 15-85 watts rms, it's power consumption is more than 200 watts. You might want to add up the power requirements of all of your pedals if you have an extensive set-up, but a simple "pedal power" unit doesn't eat too much. Even a bunch of foot pedals add up to only a couple of watts.

I have a Voodoo Pedal Power 2 Plus. Would this cause extra noise if I plug it into the amp?

No extra noise.
