## Questions & Answers

**Q: Will putting a 9v Pedal in the 12v or 18v slot kill the pedal? Shame to have 2 slots unused?**
A: Supplying 12V to 9V pedal is likely to be just fine.  ...18V is iffy, tho.  Proceed with caution.  

To do this safely, open the pedal,
find the power input regulator.  Check its datasheet to verify the absolute maximum input voltage (35V). Check any power input caps (prolly 16V or 35V).

***how-to below***

For many (most?  all? ) 9V pedals, 12V power supply is just fine.  Most analog and digital musicians' audio signals are 0-5V.  (0s and 1s arent real...?!!) PS volts are tamed by regulators and caps which can handle 16 or 35V inputs (rev polarity is blocked by a diode... usually.)

Often a 12V device may work ok on 9V, but you may get reduced headroom/distortion due to 0 to 7V or -5 to 5V.  A built in 12V battery will not charge with 9V.

Be very cautious supplying 9 or 12 ped 18V PS. It may work at first, but u will quickly fry a 16V cap, poof. (Which can be funny, and is easy to fix... if a pedal dies, check DC in caps first)
 
Generally you can safely plug an 18v pedal with 9 or 12 V but there is a good chance that it will work poorly... (although it might give an interesting distortion effect).  If an 18V ped has digital save data, better not chance it.  You may corrupt your sweet patch or loop.


***checking your voltage regulator***

Inside yer ped, the voltage regulator will be a thin black plastic box (maybe 2×2×0.2 cm) with 3 to 4 electrical connectors at the bottom.  There will be a metal heatsink protruding from the back-top. The heatsink may be connected to a larger heat spreader with a screw.  

Some text identifier will be on the front (LM805, for example).  Maybe your ped has an MC7805 made by ON Semicondoctor.  Maybe marked like: 

MC7805B
RM232
(ON)

If so, search for "ON mc7805 datasheet". If in doubt, search  all the text on yours + "...datasheet"

For such a common part, expect many search results from many companies.  Try to find the datasheet from the correct company (Motorola, fairchild, TI, Analog Devices, or perhaps a chinese company).  

One datasheet will likely cover a family of products.  On Semi's mc78xx datasheet covers many components... 

We are undaunted! Datasheets are actually quite friendly... (app notes are even better! ...so that's how they do it!) These companies know what we want!

On the first page, the first line of the first table reveals the absolute max voltage ratings we seek!  With ecstasy, we learn that a 5V regulator in the mc78xx family can accept a nominal voltage of 35V!!  

That looks good, but take care to consider the schematic on the right side of the page.  ON recomends low pass filter capacitors over the input and ouput terminals (to ground).  

Cout is no concern. It is being regulated to 5V.  *Cin*, if it exists, may be liable to pop, tho.

Cin will be easy to find.  It will likely be an elecrolytic (trash can) polar cap with 2 legs.    The negative leg is shown by a (-) and a vertical stripe along the cap.  This is the leg connected to ground.  You will notice the ground plane easily.  It will be much larger than the other electrical connections on the board.  

Cin, is given as .33uf, so if you find a .33uf cap connected over the power input, just check to see the voltage.  If it is 35V, you are innnn luck!  You may safely connect your pedal to even an 18V spot! 

Most likely, it will Cin will be 16V, which is a common value.  (Fine for a 12V power supply!!... ) i think 16v caps are common due to the ubiquity of car electric and now cheap solar (which is 11-14V...) 

So you can play with your pedals in your car...! (Not while driving..?)

If you *cant* find a Cin trashcan cap, look for a surface mount tantalum cap (a little yellow square).  These are increasingly common esp. in chinese circuit designs (like those cute Donner pedals!)

**Q: How is this different from the donner dp-1 power supply?**
A: Thanks for your questionsDP-2 is totally isolated and offer higher stable current,Output:--6 way 9V 100mA--2 way 9V 500mA--1 way 12V 500mA--1 way 18V 500mAwhile DP-1 only have 1 way 9V 500mA output ,the other output can just reach 100mA.

**Q: Funciona con pedales de la marca electro harmonix ? Tengo la duda por que mis pedales tienen un icono de -+ segun yo si se puede**
A: por supuesto que funciona con pedales harmonix, puedes conectarlo sin ningun problema.

**Q: How do i power my strymon big sky with this power brick? i tried the 500ma jack but nothing?**
A: Try the other 500ma jack, if that doesn't work, try a different power cord, if that doesn't work, put a different pedal in one of the 500ma jacks and see if it works. If nothing works on either 500ma jack, the problem is with the power supply. If the other pedal works, the problem is in your Big Sky. The Big Sky may work on battery power, but not through the direct power input. The big sky uses a negative center style power cable, which is common and uses 300ma You just have to narrow it down a piece at a time.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Affordable and versatile power supply!
*by J***R on November 19, 2020*

This is fantastic I'm super excited about it. It came in well packaged and everything you need. I have a Dunlop Slash Wah pedal that requires an 18v supply. All the others are standard 9v. So I would need to run separate supplies or batteries. This fits my needs perfectly.It goes well with my new Donner pedal boards. It also comes with 2 reverse polarity extensions if needed.I wish the adapter was longer. It is really designed for an outlet on stage or a power strip. I happen to have one so it's no worries for me. I spent a little time playing through and have experienced zero noise. Donner has been reliable for me so far. I have used daisy chains, pedals, and other products that have held up well. So I have no concerns with reliability. It's sturdy and fits well. I definetely recommend it and think it's a great value.

### ⭐⭐⭐⭐⭐ Extremely low noise, as in none.
*by C***Y on December 5, 2021*

My rig that was always horribly noisy is completely silent now. I was running on an ispot and it was demoralizing. Seriously , zero noise. You could spend a lot I guess on a big brand name, to get less than zero noise, ha!. I am pulling a lot of current on every port plus pedals that are getting power from other pedals. Including 18v to my Clone Centaur and 12 to my WAH. No issues. Now that it has proven itself out, getting second unit for my 2nd board. Small, lightweight easy to Velcro on. Good cables supplied. High quality unit, pretty jazzed about it. Shocked by how eerily quiet it is for this cheap. For giggles I plugged a daisy chain cable into it to power 3 more pedals off the 500ma port. Works, no noise. Very cool since I would rather blow money on pedals and my GAS than on power.

### ⭐⭐⭐⭐ Great except for the AC adapter.
*by A***N on January 2, 2017*

I largely agree with the 5/10/16 review by tdundas, but I would be one star more generous. The power brick itself works extremely well: it's quiet and compact, comes with a full set of connectors (including polarity reversing), and its ability to power a 12V and an 18V pedal in addition to eight 9V pedals makes it very useful and versatile. I am using it with a small Gator GPB-LAK pedalboard, which has an underside bracket that holds it securely. I don't know what more you could reasonably want from a pedalboard power supply, with one exception: the AC adaptor.One of the reasons I was attracted to this unit is its ability to power an 18V pedal. I have a Pigtronix boost pedal, which can be run at either 9V or 18V. When I connected it to the Donner's 18V output, I got a loud howling sound from the amp. I got no noise when I connected it, or any of my 9V pedals, to a 9V output. I was able to confirm that the problem was with the Donner's AC adapter, since I got no noise when I used the Pigtonix 18V adapter to power the boost pedal and the Donner to power the rest of my pedals.The seller, DonnerDirect, was very responsive and promptly sent me a replacement. Unfortunately, I still got the same loud noise when connecting my Pigtronix pedal to the 18V output. So I bought a Dunlop ECB004 US AC adapter from Amazon, which has the same specifications as the Donner AC adapter. With the Dunlop adapter, everything worked perfectly with no noise when the Pigtronix pedal was connected to the Donner's 18V output and my other pedals were connected to the Donner's 9V outputs.So be prepared for the possibility that you will have to buy another AC adapter to use with this unit. Based solely on my experience, that shouldn't be necessary if you're only using 9V pedals, and it's at least possible that you wouldn't have the problem with an 18V pedal that I had (I don't have any 12V pedals to use for a test). Worst case, you would have to spend an additional $14 for a Dunlop AC adapter, which would still leave the total cost of the unit far below any alternative. And the seller's responsiveness to my contact is reassuring. Maybe the adapter problem will be cured in future production runs.
