High Horsepower, Low Profile.
Zuma R300 is the highest horsepower, most technologically advanced low profile effects pedal power supply. You get clean, rock-steady power for your 9V, 12V and 18V 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.
Dual isolation.
Zuma R300’s all analog circuitry offers two stages of isolation, completely eliminating ground loop and AC line noise issues, allowing your pedals to sound like they were designed to sound.
Ultra-Low Profile.
Zuma R300’s ultra-low profile design means that it can fit under just about any pedalboard. With built in threaded hardware, mounting to your board is simple.
Never run out of outputs.
Have a growing rig? Zuma R300 is part of an expandable system. Add more outputs by connecting a Strymon Ojai or Ojai R30 (sold separately) with the 24V Out jack.
Expandable System
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 24V Out jack. Zuma R300 is part of a truly expandable, modular power distribution system that can grow with your pedalboard.
Ultra Low Noise
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. Their ultra-low-noise design prevents power noise from bleeding into the audio signal, allowing your pedals to deliver the highest possible dynamic range.
12V and 18V Option
12V and 18V option.
Do you have a pedal that requires 12V or 18V? Zuma R300 has you covered. One channel has selectable 9, 12, or 18V 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 12V or 18V. 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
Dual isolation.
Zuma R300’s all analog circuitry offers two stages of isolation. Each of the five output channels is individually isolated from the 24V DC, and the 24V 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
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 120V, 240V, 100V, or any variation in between, Zuma R300 will deliver clean, reliable power to your pedals, even if the venue has dirty power.
Energy Efficient
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.
Pedalboard Friendly
Pedalboard friendly.
Zuma R300’s ultra-low profile design means that it can fit under just about any pedalboard. It also features built in threaded hardware for easy mounting.
Design Team
Their power design team has over 25 years of experience in power system design, from developing mission-critical power systems for the aerospace industry, to developing best-in-class power supplies for top-selling power amplifiers, studio monitors, guitar amplifiers, and more. They’re using this vast experience to provide clean, dependable power to all of your effects pedals.
Breakthrough Technology
Strymon has solved the switching power supply problem. With their dual-stage topology, pre-regulated outputs, optically isolated feedback, and advanced multistage filtering, they have designed a switching power supply that is actually quieter than linear units.
Audio Testing
To make sure your pedalboard delivers the best sound quality possible when powered by Zuma R300, they did extensive listening tests with every pedal they could get their hands on. In fact, every Strymon power supply unit goes through the same rigorous Audio Precision testing that their pedals go through. With Zuma R300, your pedals will sound the way they were designed to sound.
