Powerbox PRO - stompbox supply

Powerbox PRO guitar effects power supply

    You have too many effect pedals? And too many supply adapters for your guitar or bass effects which take up too much space and are nothing but trouble with currents and make a lot of noise? Are you looking for a convenient solution? You want your flexible guitar effects power supply to be quiet, stable, isolated and filtered, with individually separated power outputs, different output voltage options and with no ground-loop issues! You want to power your whole pedalboard with just one cable plugged directly into the socket and to be able to power on all of your effect pedals quickly? Then the new swiss army knife guitar effects power supply Powerbox PRO is what you need!

   N-audio Powerbox PRO is a 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 cheap adapters this power supply unit is based on a 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, Eventyde, 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 idealy high current DC effects like Strymon, Eventyde, TC electronics, Line6 etc, multi effect processors or loopers. Works great with any low power effects too.

9/15/18/24 VDC Outputs 9-10
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 simulates 9 volt alkaline battery and can deliver up to 100mA per group. They has less than 130dB noise at 5mA current consumption. They are ideal for any sensitive low power analog pedal like wah pedal, overdrive pedal, booster, distortion, compressor etc.

Customisation:
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 Instriments Ventilator and other wich requres 12VAC. Also there are some 16VAC effects like Blackstar HT tube effects. For these or other effects we offer customisation with your requirements.

Powerbox PRO mains switch
Powerbox 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 requrements, please contact us.
