## Questions & Answers

**Q: Is this actually isolated? Ive seen others in this price range that appear to be isolated but the reviews have said they arent.**
A: The outputs are isolated. Looking at the photos posted by one reviewer, there is a separate voltage regulator for each output. While all the regulators get their power from the same 18 volt power pack, there is no way noise (or a short circuit) from one stomp box can feed backwards through its regulator and cause problems with the 18 volt supply or any of the other outputs. OK, maybe a lightning strike or some other catastrophic power surge in a stomp box might do it, but something that powerful could also travel through the signal cables. In other words, even though there is only one 18 volt power source, all the outputs are isolated from each other by their voltage regulator circuits. Even if they all had their own 18 volt power sources, those would all be plugged into the same 115 volt outlet, so still not 100% isolated.

**Q: Before I purchase,...some of my pedals are reverse polarity. "center pin negative" and others are "center pin positive" Will this power supply work?**
A: Mine came with two short (about three inch) cables for this purpose.  They have female connections on one end and male connections on the other end, so you would simply plug the cable coming from the power supply (the one that you want to reverse polarity on) into the female end of this cable, then plug the male end into your effects pedal.  If you have a meter handy, I would check the output of this cable before I plugged it into the pedal, just to be sure the polarity has been reversed properly.  (better safe than sorry)

**Q: Can someone enlighten me what is the 9v 500ma is for? can i use it on regular 9v boss pedal like boss cs-3?**
A: Just bought this and it looks like it won’t turn on with my RC-500 off of the 500 port.  You can plug it in once the other pedals are powered up, but it won’t power them all up together which is hella annoying.

**Q: I lost the power adapter for mine (I think someone took it) how do I replace without buying an entirely new rig?**
A: Just buy new power adapter home skillet .Just make sure the output is 18 V

### ⭐⭐⭐⭐⭐ Great product

### ⭐⭐⭐⭐⭐ Power to the people

Perfect choice for the price.

### ⭐⭐⭐⭐⭐ BAD POWER CABLE→ An UPDATE 10/15/24
*by M***R on September 26, 2024*

I just received my unit. It does not work. After some troubleshooting, determined that it is the power cord/adapter. The unit itself does work with a different power supply. However, the flow of current or electricity is not proper for some of the units because some are "ON" but don't work at all and one goes off after a few seconds. There's something very specific about the power distribution and this specific cord. I shouldn't have to research this and spend time/effort finding one when I've already purchased something for that purpose. I've contacted the company for a cord solution. Now we wait... 10/15/2024 UPDATE Donner Music (the company), ended up reaching out to me after I had sent them a note and followed the proper channels for product support. I had unfortunately already returned the item as it had been several days with no response. Long story short, they apologized for the delayed response, offered to help (if I still had it) and offered to send me a new unit to try out. The new one showed up a couple of days later. It worked just as expected. I've been able to plug in all the pedals I'm currently using for my rig, making the entire thing more efficient and "clean" which is what I wanted. Thank you DONNER MUSIC for stepping up and making things right. It is a "no brainer" type of product and so far, it works for me as intended. If you have multiple stomp-boxes, pedals, etc., to your instrument rig, I seriously recommend taking a look at one of these units and giving it a try. The LED lights give it a nice touch not just cosmetically (as it does look nice), but it gives some much-needed light when you're in a dark stage, studio room or other situation like that. I hope this helps those of you who are researching it or on the fence about getting one.
