Voodoo lab pedal power disaster!
 
Hi all

So i picked up a voodoo lab pedal power to power the 3 things on my Pedaltrain Jr. board. (Shure wireless receiver --> Peterson Tuner --> BBE acoustimax). At first I thought everything is working because everything lit up. I thought, "Cool!" But when I plug the board into my PA and plug in my guitar, I discovered that the wireless receiver was giving a huge "hum". Because the receiver goes ino the Peterson tuner, the tuner didn't work either. I tried every cable that came with the Voodoo Lab and tried every power outlet on the unit but nothing helped. Just as an experiment, I unplugged the voodoo lab and use the power adaptor that came with the Shure wireless unit and everything worked fine. I guess I should just take the voodoo lab back? Or am I missing something?

sounds like it could be a polatiry issue. make sure the polarities on the cable coming out of your power supply into your wireless system match. that's the only explanation i know enough about to explain what it could be.

If thats the case then there should be a reversed polarity adapter you can buy for your voodoolabs power supply

In addition to polarity, what is the volt requirements of the wireless unit? The PP defaults to 9v outputs, and you may need to change that in order to match what the wireless transmitter wants.

I checked my Shure wireless unit and it takes a 12V power supply. That was one of the things I checked before picking up the voodoo lab, that it supports 12V pedals.

can someone tell me more about the possibility of a polarity issue and what i can do to find out for sure?

But did you set that particular output on the power supply to 12v?

hm...i don't think there is anything to set on my voodoo lab unit (Pedal Power AC). There are two pairs of 9V/12V outputs and you simply choose which one to plug into, depending if you want 9 or 12.

Did you mean Pedal Power AC? If that's the case, that might be your problem - do your devices need AC, or DC?

stephenT 03-23-2010 09:35 AM

there are dip switches someplace on that unit.

here's a link to the manual

Thanks, but I only have the original version: the Pedal Power AC rather than the Pedal Power 2 Plus.

I have ALWAYS found that making a call to the Tech Support of any company is ALWAYS worth the call!

The BBE Acoustimax requires 12V AC.

I don't know which Shure wireless unit you have, but the three models I checked at random all need 12-18V DC.

Similarly for the tuner - I checked a couple of Peterson models, and they required 5V DC (StroboFlip) or 9V DC (StroboStomp).

Based on that, the Acoustimax is the only device you have that can be powered by the Pedal Power AC.

Thank you for your help...I guess the voodoo lab is going back to the store. Out of curioristy, is there something else out on the market (power supply for pedal boards) that can do what I need?

David Eastwood 03-23-2010 11:36 AM

The Voodoo Labs Pedal Power 2 Plus should do what you need, although it might be overkill for you. It's DC only, but it has an AC outlet built in which you could plug your BBE power supply into.

Don't know if it will fit in a Pedaltrain Jr, though.

Original Pedal Power Dip Switches (Hope this helps)
 
From what I understand the Original Pedal power has Dip switches on the underside. If they are in the ON position it is for the 9 volt supply, if the switch is in the OFF position it is for 12 volt supply. (Which is the complete opposite of the Pedal Power 2 version).
