Powering a Digitech XP-100

Sign in to disble this ad
Hi guys,

I've recently bought a Digitech Xp-100 and I'm not sure how to power it. As far as my research has shown me, it runs on 9v AC 500mA (although it doesn't say on the pedal itself) and all my other power supplies are DC.

So if I run it through an DC power supply, I'll fry the pedal right?

Do any of you guys own the Xp-100, or have any recommendations as to which powersupply would fit the Xp-100?

Thanks.

hmm first off im assuming the AC at the end of the first paragraph is meant to be a DC right? and the one in the second lol

Anyway yeah it would most definitely not be a good idea, DC operates off a positive and a negative whilst AC power just has two signals

You just need to find a 9v AC power supply with 500 or more mAh on tap, any lower and you will fry the power supply as current is drawn not sent. the 9v AC HAS to be 9v AC though is teh bottom line, you need another wall wart

the voodoo AC is not worth it for one pedal :P

Yeah, you're right TimmDX, I messed it up in my initial post.

I've just ordered a T-Rex Fueltank Classic which has an isolated 12v AC output - would that be a possibility?

I'm a complete n00b when it comes to electronics..

mmmm no the voltage can't be greater only the amperage.

basically with every power supply/pedal your going to get a Voltage and amperage number

Voltage the voltage will be X volts DC or X volts AC, it MUST have the right X value and it MUST have the right AC/DC, some pedals like the semaphore tremolo can take 9v or 18v DC but it is clearly indicated on the pedal, the whammy can't as it doesn't have this.

Amperage will given in mAh, this is what the pedal draw's on for power, it's how much juice the supply must have available. Thus it can be as high as you want. You can run a pedal that only needs 500mAh off a 1200mAh supply and it wont matter.

The current whammy power supply works just fine.

I found a powersupply in Germany that does the job.

...Damn I love that 1 up/5th up setting!
