Under the circumstances of all LED lights on, LED light of the short-circuited channel will off, while lights in the other normal channels are still on. This helps locating the faults when there were short circuits among many effectors. Attention: Incorrect polarity would damage this unit, please make sure correct positive and negative polar before wiring. Package included: 1 x Donner DP-1 Supply 1 x Power Adapter 10 x DC Power Cable 2 x Polarity Reversal Cable 1 x User Manual Review: Good Product - Used it with my set of pedals. Less Noise. Durable. Affordable and Quality Product. I suggest using a spike guard before using this power supply. Review: Dont Buy non isolated fake chinise power supply - using it for around 3 months. I heard a rattle noise come from this. I opened it and found that a capacitor drysold inside, and also it's NOT Isolated it's a daisy chain with a series connection .worst product. my, all money drained .beaware of this fraud product of Chiana. ## Features - 10 ISOLATED OUTPUTS:Donner DP-1 9V Guitar Pedal Power Supply has 10 outputs ,which includes 7 ways 9V 100mA, 1 way 9V 500mA, 1 way 12V 100mA, 1 way 18V 100mA - NOISE REDUCTION CIRCUIT DESIGN：Donner Guitar Pedal Power Supply Quality is made of aluminum alloy material, which makes it light, and portable.

Due to the difference of production batches, the Donner logo on the product you received may be different】 - Note: Donner uses circuit simulation technology and circuit design on the switching power supply to achieve the isolation effect of the independent power supply of the effector. However, it does not mean absolute isolation in the circuit. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00WHLLDWO | | Amperage | 500 Milliamps | | Best Sellers Rank | #1,613 in Musical Instruments ( See Top 100 in Musical Instruments ) #1 in Guitar & Bass Effect Accessories | | Box Contents | Adapter | | Brand | Donner | | Brand Name | Donner | | Colour | Black | | Connector Type | 9V, 12V, 18V Barrel Jack | | Connector Type Used on Cable | 9V, 12V, 18V Barrel Jack | | Customer Reviews | 4.5 out of 5 stars 7,177 Reviews | | Enclosure Material | Aluminium | | Form Factor | Compact rectangular box | | Input Voltage | 12 Volts | | Item Dimensions | 15.2 x 5.1 x 182.9 Centimeters | | Item Weight | 6.9 Ounces | | Item Weight Unit of Measure | 6.9 Ounces | | Manufacturer Part Number | DP-1 | | Material | Aluminium | | Maximum Power | 9 Watts | | Model Number | AS2401A | | Output Current | 12 Amps | | Output Wattage | 9 Watts | | UPC | 708302975773 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Donner - **Colour:** Black - **Connector Type:** 9V, 12V, 18V Barrel Jack - **Item Weight:** 6.9 Ounces - **Material:** Aluminium ## Images ![Donner Dp-1 Guitar Pedal Power Supply 10 Isolated DC Output for 9V/12V/18V Effect Pedal - Image 1](https://m.media-amazon.com/images/I/71zv85gC7JL.jpg) ![Donner Dp-1 Guitar Pedal Power Supply 10 Isolated DC Output for 9V/12V/18V Effect Pedal - Image 2](https://m.media-amazon.com/images/I/71-HqH+ryKL.jpg) ![Donner Dp-1 Guitar Pedal Power Supply 10 Isolated DC Output for 9V/12V/18V Effect Pedal - Image 3](https://m.media-amazon.com/images/I/71REwrLvocL.jpg) ![Donner Dp-1 Guitar Pedal Power Supply 10 Isolated DC Output for 9V/12V/18V Effect Pedal - Image 4](https://m.media-amazon.com/images/I/61TQBEaahIL.jpg) ![Donner Dp-1 Guitar Pedal Power Supply 10 Isolated DC Output for 9V/12V/18V Effect Pedal - Image 5](https://m.media-amazon.com/images/I/71VCGBxIaoL.jpg) ## 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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good Product *by R***L on 15 January 2019* Used it with my set of pedals.
