Carl Martin Pro Power V2 Power Supply

Innovative Music | (03) 9540 0658 | | RRP: $269

Pedal usage for guitarists seems to have boomed again over the last few years, and although there are some dedicated battery users out there the majority of players then need a power supply to handle their boards. Plus you have to factor in the multitude of voltages, requirements and the fact that a lot of pedals only run on mains power these days. The Carl Martin Pro Power V2 seems to offer a lot as a solution for your pedal power needs, let’s delve a little further.


Hailing from Denmark, Carl Martin produce a host of effects, amps and accessories including switchers, buffers and power supplies. Following on from their original Pro Power, the upgraded V2 sees 8 individual isolated and regulated 9v – 12v outputs (150mA each) with outputs 7 and 8 able to be extended to 350mA at 9v or 300mA at 12v. The whole unit is housed in a tough casing (in you guessed the colour – black) and can be switched between 110v or 230v, meaning it’ll be compatible in a range of countries too.


So you’ve got your board together and you want to incorporate a power supply. The Pro Power V2 will sit comfortably under a lot of mass produced boards which often come pre-slotted for brackets and the like. Otherwise it’s easy enough these days to afix it securely whilst still giving you access to the outputs. I’ve also often sat a power supply on top of my board with Velcro like you would a pedal and even sat a tuner on top of it. The Pro Power V2 is about the average size for a power supply of this ilk (17cm x 9 x 4.5) so you should have no problems however you want to attach it. Once it’s in place you then get your power options cracking – 2.1mm jack, battery clip, 1/8 jack, 2.1mm jack (negative barrel, positive tip) and some 2.5mm jack plugs (neg/pos and pos/neg polarity) plus some voltage doubling cables. These should cover a lot of ground with your effects and it’s then as easy as selecting 9 or 12 v for each output via the DIP switches on the back.


If you’re running multiple pedals you really owe it to yourself to get a power supply. It centralises the whole power thing, performs better than a daisy chain, is generally quieter and really – think about the amount of money players spend on their pedals to only power them with a $3 daisy chain and wall wart from your local electronics store. Doesn’t really make a lot sense.
