Pedal Power Supply Adapter DPA-1, Donner 9V DC 1A Tip Negative 5 Way Daisy Chain Cables for Effect Pedal

I have just ordered another of these adaptors making it four I have in total. I have noticed quite a number of reviews mentioning a “high pitched electrical whining” but must admit I haven’t had any such issue. My main set-up (I have two in other rooms, but they are much smaller) consists of a number of different manufacturer pedals supplied by two of these supplies. Two pedals (Behringer Digital Reverb and Digital multi Effects) are placed in the effects loop and another seven running before the amp (Donner DT Deluxe Tuner, Behringer Compressor / Sustainer, Behringer Hell Babe Wah, Donner Tube Drive, Behringer Vintage Tube O/D, Behringer Tube Amp Modeler and Behringer Noise Reducer. There is also a Neewer pedal switching the amp’s own overdrive and refurb separately. This is plugged into the amp by it’s own dedicated jack socket and as a switch only, has no requirement of a power supply. I only mention the pedals by manufacturer and type in order to make the point that this is hardly a top end set-up and these pedals and powers supplies are the type you would expect to hear of users having noise issues and constant other problems besides. I have purchased this gear over the last twelve months as I’d returned to playing after a long break and wasn’t 100% sure I’d keep it up. On and off I have been playing for around thirty six years, so I’m not a Newbie. I’m very pleased to be able to say here that I’ve had no problems whatsoever with any one item (the pedals are also linked together with two different types of Donner patch cables). My personal experience with all the Donner kit purchased has been excellent. I really can’t praise the equipment highly enough and the value for money is unbelievable. I can only go by my findings but I’d certainly have no hesitation recommending the company’s gear and if required in the future I would again save myself some cash (possibly quite a bit actually) and buy Donner stuff from Amazon with confidence.

Geat unit ! Great price ! Works really well. I have had this for some years now, with no problems

It's a daisy chain power supply, and as such you can expect there to be noise. If it's for a rehearsal or practice board then you cant knock the quality of it. But if you're going to be going out on stage you might want to look at spending more money on a high quality fully isolated power supply. Low quality power = low quality sound. If the power isnt right, your pedals won't sound right. It's that simple. But for what this is and for the price, you cant knock it

Great addition for pedals ..

PSU works well. I'm always loathe to pay for the brand name or more expensive power supplies if I can avoid it. This one works perfectly well for my fender marine reverb, boss dd3 delay, fender compressor and twinote chorus. It buzzes when connected to my ehx hot wax but so does a more expensive boss psu I own. Interestingly there is no discernible difference in hum noise, even with a compressor between this power supply and the boss one so it does a pretty good job. I can't hear humming so I'm happy. I bought some additional ferrite clip on thingies to see if I can clean up the buzz and improve the hot wax pedal but didn't work. Now looking at separate leads as think the gain on OD pedals is amplifying digital noise from another pedal since they're daisy chained.

I bought this to go with my Pedaltrain and to distribute power to pedals it is excellent because it introduces no noise. The power supply itself is not perfect but I did not have need for this anyway so not concerned.

It works. Powers 5 pedals witout issues.

Needed a second power supply for a small 5 pedal pedalboard with daisy chain for open mics. Had a 500ma power supply - but it had a serious hum. This 1000ma power supply has no hum but hisses seriously loudly with digital pedals. So not so impressed.
