Excellent power supply

20.09.2015
This is supplied in a neat cardboard box. Inside lurks the Powerplant Junior, a bag of cables and manuals in English and German. The unit is a robust pedal-sized folded steel box held together with screws. It comes with a captive 135cm mains cable terminated in a Schuko mains plug. As I'm in the UK, Thomann supplied a Schuko to UK adapter with it free of charge. This adapter is robust and works very well. On plugging in, an LED shows the power is on. The unit hums very slightly acoustically, but this is not audible from a few feet away. The black foam feet on the base help with this aspect.

The five 9V DC ouputs are all tip negative, as most pedals require, and are ideal for powering a reasonable sized selection of pedals. Each output is isolated from each other, so this stops ground loops forming, which usually result in obnoxious hum.

A good selection of power cables are provided. There are two sets of standard DC cables (5 short and 5 long), terminated with barrel connectors (right angle at one end and straight at the other). Having both lengths make for neater wiring on a pedal board, without excess cable needing to be coiled up. A "Y" cable is supplied, for powering pedals that need more than 120mA of current. Lastly, a daisy chain cable is included so you can power more than 5 pedals. Some pedals suffer less with ground loops, and the daisy chain will work for those.

In use, my pedals are super clean and quiet with the PowerPlant Junior. It's a huge improvement over batteries, a daisy chain cable, or using multiple power supplies. 120mA per output seems fine for my pedals. It might struggle on some power hungry pedals but the current doubler cable is there for those situations. The standard 120mA output powered a digital delay of mine with no problems.

In conclusion, this is a great product at a bargain price. I should have bought one of these ages ago.

Small and silent

DominicJ, 13.10.2014
Many people, especially beginners but also the more advanced ones, often seem to struggle when it comes to powering their effects and pedalboards. The most common problem is noise and hiss appearing in different situations. These effects often appear when people power their pedals with several wall warts, when using analog and digital pedals on a single power supply or when using effects in front of the amp and in the FX-Loop on single power supply. I really think powering your pedals isn't that hard to do. Although I often use a Visual Sound One Spot Power Supply when I need to supply one or two effects with power, I think one should use a regulated power supply like the Harley Benton PowerPlant Junior when you need to supply a bigger pedalboard. The advantage is that you get regulated power which is far less prone to noise and every single output is isolated. The isolation of every output is a very important thing especially when you want to use digital and analog effects at the same time or pedals in front of the amp and in the FX-Loop at the same time, because the isolation avoids ground-loops that can appear if the grounds of every output aren't isolated from each other. With the Harley Benton PowerPlant Junior you get five single isolated outputs. That's enough for a smaller pedalboard but you could use a daisy chain to multiply the outputs. You should consider that the current of every output is limited to about 120mA. That's enough current for most analog pedals but digital pedals often tend to draw more than 120mA. If you need more current you need to put two outputs in parallel. The output could also be used to double the voltage by putting them in series. There are cables from Voodoo Lab etc. for that purpose. All in all it's a great product that you should consider if you are looking out for a new power supply.
