A "Switching" power supply is able to handle much more current than the older, transformer-based units. Therefore you needn't worry if your pedal's current draw slightly exceeds the stated amount on your output - so long as the total across the board doesn't exceed 1900mA. What's in the Box? Radial Tonebone 15Vdc pedals can be powered by an 18Vdc output, using the Reverse Polarity Converter (CYR) included with the 1 SPOT Pro. We recognize that not all guitar pedals run off 9V. That’s why all 1 SPOT Pro models have outputs that can put out 9Vdc, 12Vdc or 18Vdc. The CS12 even has a variable voltage output for old-style fuzz pedals, and a 9Vac output for certain Line6 and Digitech pedals. And if you need to change the voltage of an output, Truetone also makes inexpensive converter cables to help you. There’s the Voltage Doubler, which does exactly what its name says, and the 18V to 9V Converter... which also does what its name says. They don’t have the most clever names, but they get the job done!

Since pioneering the first switching power supply for musicians, the original 1 SPOT, we’ve gained many years of experience in creating very low noise power for pedals. When we started designing the 1 SPOT Pro, the first multiple output switching power supply, we worried a lot about how to eliminate noise completely. Isolation is part of the solution to noise elimination, but not all of it. Each output is galvanically isolated from the other to help give you pure, clean, noise-free operation of your pedals. However, we also provided an additional layer of pure analog regulation, taking advantage of the greater ability of analog circuits to provide the highest possible suppression of in-band audio noise. There is an artistry involved in these designs, and it’s come at the price of decades of hard work. But all of this put together is what we call Pure Isolation. Specifications: The most important decision you need to make when buying one of the best pedalboard power supplies is whether you need isolated outputs or not. Essentially, isolated outputs supply each pedal with its own individual power source, which removes hum from the equation – something you may experience when running digital and analog pedals together from the same daisy chain. Unless you’re only running a handful of analog units - which is highly unlikely these days - we’d always recommend an isolated pedal power supply wherever possible. Who knows how your rig might change in the future? What power supply do I need for my pedal board? Note: Outputs 1-11 can each handle more than the stated mA number. However, it is important to never exceed the max. current rating of all outputs simultaneously. Just like its bigger brothers in the 1 SPOT Pro line, the CS6 has a variety of DC voltages available to power just about any pedal on the market. Each output is completely isolated, regulated and filtered, eliminating crosstalk and noise. With no big transformer to hinder their performance, proximity noise is not an issue with any 1 SPOT Pro.With optional converter plugs, the 1 SPOT will work with virtually ANY 9V pedal! …even Line 6 modeling pedals! ** x CL6 – (5.5x2.1mm barrel input, 5.5x2.5 barrel output; reverse polarity) Green – for Line 6 DL4/M9/etc. and some Eventide pedals.

You can even use the 1 SPOT anywhere in the world without a voltage converter because it automatically converts voltage worldwide. No need to worry about AC hum interfering with your sound either... the 1 SPOT is one of the quietest power sources you can buy. Line 6 M9 may be powered by outputs 10-11, but will also require the CL6 converter. The M9 can also be powered directly by the 9Vac of output 12. You need to assess your pedals’ power requirements: do they all need 9V, or are some running at 12, 15 or 18V? It's worth noting that some overdrive pedals offer the ability to run at higher voltages for increased headroom, too. If more 9Vdc pedals need to be powered, a MC5 daisy chain (sold separately) may be plugged into any of the 9Vdc outputs depending on mA draw. Now available from Merchant City Music, online and in our Glasgow store, the Truetone 1 Spot pedal AC adaptor is the solution to your niggling pedal powering problems. We ship fast to the UK and Europe. Truetone 1 Spot Power Supplyx CL6 (5.5x2.1mm barrel input, 5.5x2.5 barrel output; reverse polarity) Green for Line 6 DL4/M9/etc. and some Eventide pedals. The Truetone 1 Spot Pro CS7 Power Supply compes complete with everything you need to simply plug-and-play.

Many of the power supplies in this guide offer switchable voltages, and some can even ‘sag’ below 9V to yield dying battery sounds from fuzz pedals. Clever. If you’re a touring musician, or even if you just play at the local pub regularly, you know how important it is to have road-worthy gear. No worries with the 1 SPOT Pro. The housing is all steel, with cleverly designed vents that should keep out the accidental beer spill, should that ever happen. And the CS6 is completely sealed for extra protection. This switching technology is able to handle much more current than the older, transformer-based power supplies. This means you don't have to worry if your pedal's current draw slightly exceeds the stated amount on your output - so long as the total across the board doesn't exceed 1600mA. The 1 SPOT Pro CS6 includes a generous assortment of cables and converter plugs. The cables are of various lengths, color-coded for easy cable management and with right angle plugs on the pedal end. True to the spirit of the original 1 Spot power supplies, the new 1 Spot Pro range uses exactly the same switching power supply technology.The Walrus Audio Phoenix is an absolute beast, giving you isolated power that can handle 9, 12 and 18V power in a total of 15 different pedals. Four 300mA outlets are available and made to handle larger pedals while keeping your signal clean and noise-free. Toroidal transformers assist in this process by providing noise filtering and clean power.
