Powers Eight Pedals and Your Mobile Device — at the Same Time

The ART ISO-8U pedalboard power supply gives you eight noise-isolated outlets, selectable voltages, and enough included connection cables (barrel jacks, 3.5mm, battery clip) to feed your whole pedal fleet. In addition to its impressive pedal-powering potency, the ISO-8U also gives you a 10-watt USB charging outlet to keep your phone or tablet juiced up for the soundcheck, gig, and return trip. It's slim enough to slip under a standard pedalboard, and even includes tie wrap slots for a clean installation. Fly date? The ART ISO-8U includes a universal power supply to keep your pedals juiced up from Burbank to Bangkok. All told, if you're chasing an 8-outlet isolated pedal power supply that doesn't break the bank, the ART ISO-8U is one unit that's worth a look.

Eight isolated pedal outlets

All eight outlets on the ART ISO-8U are isolated to remove ground loops and circuit protected to prevent damages from faults, shorts, current spikes, or temperature overloads.

Switchable 9–12V operation

Seven of the ART ISO-8U eight outlets can serve up standard 9V or less-common 12V DC. Just slide the DIP switches on the side to lock in your preferred settings, no matter where you pedals land on your board.

Worldwide compatibility

An included universal power supply keeps the ART ISO-8U rockin' in the free world to the most remote corners of the earth.

Main outlet with Voltage Adjust

Players like Eric Johnson insist on keeping boxes of dying batteries on hand to deliver the sputtery, saggy sweetness of a failing 9V into a fuzz or overdrive. The ART ISO-8U seeks to replicate this effect without batteries by giving you variable 4–9V output on outlet 1.

Two high-gain 250mA outlets

If you've got a pedal with a draw exceeding the 100mA allotted to outlets 1–6, outlets 7–8 net you a full 250mA of output to keep your current-hungry pedals well fed.

USB outlet for your phone or tablet

Many players throughout the industry— including many at Sweetwater — rely on mobile devices to supply backing tracks, amp modeling, MIDI conversion, and mobile photography in the heat of a performance. The ART ISO-8U gives you a fast-charging 10W USB-A outlet right on the front panel, allowing you to keep your phone or tablet charged during and after the gig.

ART ISO-8U Pedal Power Supply Features:

  • 8 isolated outlets eliminate ground loops between pedal effects
  • Switchable 9–12V operation supports most pedals on your board
  • Voltage Adjust on outlet 1 simulates the effect of a dying 9V battery — great for fuzz
  • 250mA outlets 7 and 8 keep current-hungry pedals well fed
  • Fast-charge 10W USB outlet for phones and tablets
  • Tie wrap slots for easy mounting on a pedalboard
  • Universal power supply for worldwide operation
  • Includes connector cables with 2.1mm barrel jacks, 3.5mm, and battery clip
