Strymon Zuma R300 High Current DC Power Supply

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.

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

 
Expandable system

Add more outputs to your Zuma R300 by connecting a Strymon Ojai or Ojai R30 (sold separately) with the 24V Out jack.

Ultra low noise

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.

12v & 18v options

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 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.

World tour ready

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.

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.

Energy efficient

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.
