Zuma

High Current DC Power Supply

Strymon Zuma is the quietest and most powerful pedal power supply of its kind, capable of powering a huge number of guitar pedals silently and reliably with a staggering 500mA of current available at each output. With nine high-current, individually isolated, ultra-low-noise outputs – each with its own dedicated regulator and custom transformer – Zuma is the most advanced isolated pedal power supply available today.

A pedalboard can be a noisy place, and your choice of power supply can have a huge effect on the noise level and transparency of your guitar tone. We designed Zuma to address the main pain points guitarists face with dual-stage topology, pre-regulated outputs, optically isolated feedback and advanced multi-stage filtering – so you can rest easy at the gig, knowing that your pedals and rig will sound the absolute best that it can.

Never run out of outputs.

Have a growing rig? Or unique requirements that require distributed power?

Add more outputs to your Zuma by connecting a Strymon Ojai  or Ojai R30 (sold separately) with the 24V Out jack.

Use Zuma by itself if that’s all you need, or as 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.

Our ultra-low-noise design prevents power noise from bleeding into the audio signal, allowing your pedals to deliver the highest possible dynamic range.

World Tour Ready

Playing gigs all around the world? No need to purchase separate power supplies for your international tour.

Zuma 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 will deliver clean, reliable power to your pedals, even if the venue has dirty power.

12V and 18V Options

Do you have pedals that require 12V or 18V? Zuma has you covered. Two channels have 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

Zuma’s all analog circuitry offers two stages of isolation.

Each of the nine 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 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.

Energy Efficient

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