Powerbox PRO

N-audio Powerbox PRO is a linear power supply for effect pedals. It is based on our bestseller Powerbox Mk2, but the PRO version has two more isolated high current switchable AC/DC output groups. Unlike most of the adapters, this power supply unit is based on high-quality transformers with a reduced flux density to reduce noise and gives you 7 independent galvanically isolated output groups. Each group can supply two effects pedals (14 pedals in total). The output voltage of most output groups can be changed via DIP switches at the top of the unit. All DC outputs are short circuit protected.  Due to the galvanically isolated groups, Powerbox PRO power supply for effect pedals guarantees a significant decrease of noise and ground loop problems. Additionally, thanks to the galvanic isolation, you can use it for supplying pedals that require AC effects, 18 or 24 VDC guitar effects or effects with center positive supply, for instance, fuzz faces, germanium boosters, tycobrahe octavia style octavers and others.

Powerbox PRO pedalboard power supply for effect features:

9 VAC, 9/12 VDC (Outputs 1-4)

Four high current AC or DC outputs. Each of these output groups can deliver maximum 1500mA for 9VAC effects like a Digitech Whammy, JamMan, Line6 pedals, ISP Theta and many more. Can be used also as a high current DC supply for your Strymon, Eventide, TC electronics, Line6 etc, multi-effect processors or loopers. Works great with any low power effects too.

9/12 VDC (Outputs 5-8)
These outputs can deliver up to 520mA current per group. They are ideally high current DC effects like Strymon, Eventide, TC electronics, Line6 etc, multi-effect processors or loopers. Works great with any low power effects too.

9/15/18/24 VDC (Outputs 9 and 10)
These outputs are ideally for some 24 volt Electro-Harmonics effects, 18 volt boosters/overdrive pedals like Cmat mods Browne. Can power 15 volt Radial Tonebone effects and also high current 9 VDC effects. Works great with any low power effects too.

Ultra low noise 9.5 VDC  (Outputs 11-14)
These ultra low noise outputs simulate 9 volt alkaline battery and can deliver up to 100mA per group. They have less than 130dB noise at 5mA current consumption. They are ideal for any sensitive low power analog pedal like a wah pedal, overdrive pedal, booster, distortion, compressor etc.

What's in the box:
Powerbox PRO is available in a kit of all necessary cables for powering effects, which content:
  • Standard IEC power cord with EU, UK or US plug 
  • Eight standard black cables with a diameter of ø5.5/ø2.1 mm and  length of 50 cm
  • Two (red and blue) cables with a diameter of ø5.5/ø2.5 mm and length of 35 cm
  • One black cable with 3.5 mm mono jack output and length of 35 cm
  • Three reverse polarity cables with a length of 15 cm
  • One current doubler Y parallel cable

Outputs voltage and maximum current consumption:

The AC output voltage of Powerbox PRO is fixed to 9VAC. There are some guitar effects like Mesa boogie V-twin, Hughs & Kettner Tubeman, Electro-Harmonics Tube Zipper, English Muff'n and Wiggler, Neo Instruments Ventilator and other which requires 12VAC. Also, there are some 16VAC effects like Blackstar HT tube effects. For these or other effects we offer customization with your requirements.
Powerbox PRO comes with fixed mains supply 115 or 230VAC, but we can add a voltage selector: 115-230VAC, placed on the bottom of the supply on request. For these or any other specific requirements, please contact us.
