I really have no clue what I'm doing wrong here! Help!

The only thing I can think of is your power supply may be delivering the correct voltage just not enough current That would be why it works on it's own power supply.

 

My money's on you being out of juice. The Moskey power supplies get mixed reviews, including some accusations of corporatespeak fluffing of features... and while I see it draws 1000mA current, I can't find info on its total output. It may deliver less than that.

And, seeing you've got a healthy set of pedals on it already, I'd suggest testing it by bypassing/unplugging a couple other pedals and seeing if you can get a good signal out of the WTDI then.

Or are you saying that you've already tried that, and the WTDI only works on the Moskey when run by itself?

 

Some of those other ones are light loads and the Pre probably wants more than what is left over for it

 

The WTDI asks for 400ma and uses about 90 when on.
Polarity is tip +.

 

To me the reason sounds as described above.

The power supply can't provide adequate juice.

Check the milliamps needed by the pedal against that supplied at each power tap on the power supply. I'm pretty sure you'll find the unit simply can't provide the 400ma necessary per output. The popping noise sounds like the pedal can't effectively turn itself on due to starved voltage.

 

Read The Friendly Manual:

Output:
1 to 7 Output : 9V 100mA
8 Output :9V 500mA
9 Output :12V 100mA
10 Output :18V 100mA

 

Well according to the above you do not have the current to run that pedal at 12 or 18 volts. Both only supply 100mA and you need 400 mA.

 

On the other hand, it's possible for units to "fudge" those numbers apparently. I found that out when seeing if I could run a Two Notes Le Bass on my OneSpot CS12; I should not have been, as its 12V output is rated 100mA vs the Le Bass wanting 500mA. However, I read that it'll draw as much as it needs as long as the whole unit doesn't get overdrawn, and sure enough, it ran fine.

That could certainly depend on the specific power supply, of course.


& I wonder if some of the other pedals, if not actively processing signal, take reduced amounts of power to run? TC Electronic pedals are essentially tiny computers, so it wouldn't be out of the realm of reason.

 

That makes sense also maybe the Powersupply is not functioning properly? Try turning off a pedal at a time and see when the WTDI starts working. If all the pedals have to be off for it to work either the power supply is Wonky or it just does not produce the juice to run them all.

 

The WTDI comes with its own 15volt 400mA power supply. You shouldn't have to buy another one, just use the one that came with it. I love mine. I don't have a peddle board though. I have Eden and DNA gear and I just use mine when I'm forced to use a backline or go direct "into the board". When using it in a backline amp I just plug the 1/4" output into the effects-return of the backline amp. That bypasses the backline amp's preamp and I get instant Eden sound. I recently used it at a recording session and the engineer had to come out and get a good look at what I was using that sounded so good.

 

I had a similar experience with another pedal pre. Turned out the mA rating wasn’t high enough on the supply I was using. I’m thinking that might be the issue, which others have also mentioned.

 

OP, if you have the power supply for the unit and you have a AC out on the power brick on your board, if there is room, plug power supply into the bower brick and you are good to go.

 

For starters your pedalboard has too much stuff.

Here's mine... Less is more

 

Always has to be one in every effects forum crowd.

Anyway, stuff like your WTDI wanting special power requirements and reversed power plugs in today's world really bugs me. There are a million preamps out there that don't require 400 mA and center positive. What could it possibly do that requires 400 mA, and why, in a world where center neg is the standard, are companies still building pedals like this?
