Strymon Zuma R300 Pedal Power Supply

Ultra low-profile DC pedal power supply
MFR# Z12A-R300

Product Description

High Horsepower, Low Profile

The Strymon Zuma R300 is the highest horsepower, most technologically advanced low profile effects pedal power supply. You get clean, rock-steady power for your 9, 12 and 18 V effects pedals in a pedalboard friendly, expandable package, giving you room to grow. Zuma R300’s ultra-low profile design means that it can fit under just about any pedalboard. Dual-stage topology, pre-regulated outputs, optically isolated feedback, and advanced multistage filtering result in a power supply that allows your pedals to achieve their highest possible dynamic range.

Never run out of outputs

Is your pedalboard growing? Add more outputs to your Zuma R300 by connecting a Strymon Ojai or Ojai R30 (sold separately) with the 24 V Out jack. Zuma R300 is part of a truly expandable, modular power distribution system that can grow with your pedalboard.

Hear your pedals, not your power

Many popular guitar pedals were originally designed to work with batteries. Since batteries are inherently very low noise and not susceptible to ground loops, these pedals often were not designed to be resistant to noise from power supplies. The ultra-low-noise design prevents power noise from bleeding into the audio signal, allowing your pedals to deliver the highest possible dynamic range.

12 and 18 V option

Do you have a pedal that requires 12 V or 18 V? Zuma R300 has you covered. One channel has selectable 9, 12, or 18 V output voltages. Some analog pedals designed for 9V operation may provide higher output and/or more clean headroom when run at higher voltages such as 12 or 18 V. However, others will simply start smoking and melting, so please check with the manufacturer of your pedal before operating at a higher-than-standard voltage!

Dual isolation

Zuma R300’s all analog circuitry offers two stages of isolation. Each of the five output channels is individually isolated from the 24 V DC, and the 24 V DC is isolated from the AC input power, eliminating ground loop and AC line noise issues. Zuma R300 also provides dual power regulation: Wide-bandwidth optically isolated feedback loops on each channel, as well as on the input, allow both the input and outputs to adjust for changes, ensuring solid output under changing load conditions.

World tour ready

Playing gigs all around the world? No need to purchase separate power supplies for your international tour. Zuma R300 has automatic worldwide power compatibility built-in (when connected with the appropriate IEC cable). Whether you’re on 120 V, 240 V, 100 V, or any variation in between, Zuma R300 will deliver clean, reliable power to your pedals, even if the venue has dirty power.

Energy efficient

Don’t let the blue chassis fool you: Zuma R300 is green at heart. Significantly more efficient than linear power supplies, Zuma R300 is able to deliver substantially more current while handling a much wider range of input voltages. The high efficiency design delivers high-current power distribution in a compact unit, for a small carbon footprint and a small pedalboard footprint.

I/O:

  • 5 high-current, fully isolated outputs with center-negative polarity - 4 dedicated 9 V outputs (500 mA), and 1 adjustable output offers 9 V (500 mA), 12 V (375 mA), or 18 V (250 mA) DC options
  • 500 mA per 9 V output powers nearly any pedal
  • Delivers a maximum of 36 W
  • 5 pedal cables included (5.5 mm x 2.1 mm barrel connectors, right angle to right angle, 18″ length)
  • IEC cable included
  • 24 V Thru jack allows connection to Strymon Ojai or Ojai R30 (sold separately)

love it, took care of my pedal board noise issue with its isolated power supplies, plus less wall warts to carry and set up a gig.

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.

From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
