Zuma R300
$229Reference price
The Zuma R300 is a low-profile, high-power supply for effects pedals. It delivers clean, stable power to each pedal. Connecting an Ojai extension unit allows the system to be expanded.
A low-profile, high-power supply that hides under the board
A slim power supply with five high-current outputs of 500mA each. Every output has its own independent regulation circuit and custom transformer, delivering ultra-low-noise power to your pedals.
Solving the noise problems of switching power supplies
A two-stage design of pre-regulated outputs, optocoupler-based isolation circuitry, and multi-stage filtering achieves a switching power supply that is more efficient than a linear supply while staying clean. The fully isolated outputs suit boards that mix DSP-based digital pedals with analog pedals.
Voltage switching and expansion
One of the five outputs can be switched between 9V, 12V, and 18V, accommodating pedals that gain headroom at higher voltages. Connecting an optional Ojai-X or OR30-X extension kit to the 24V output adds more isolated outputs.
A slim 30mm-tall design
Thin enough to mount directly under most popular pedalboards, with a power input that accepts 100-240VAC. The chassis is lightweight, rugged anodized aluminum.
