The Strymon Ojai R30 is a high-current DC power supply designed for powering effects pedals, offering a modular and expandable solution for pedalboards. Its primary function is to deliver clean, isolated power to multiple pedals, minimizing noise and ensuring consistent performance.
Function Description:
The Ojai R30 serves as a central power hub for effects pedals. It takes a 24V DC input from an external power adapter and distributes it to five isolated outputs, each designed to power a single pedal. The isolation of each output is a key feature, preventing ground loops and electrical interference that can introduce unwanted noise into the audio signal. This makes it particularly suitable for complex pedalboard setups where multiple pedals, especially digital ones, might otherwise create noise issues. The unit is designed to be highly efficient and compact, allowing for easy integration into various pedalboard configurations. Its expandability is another core aspect, allowing users to link multiple Ojai units together to power a growing number of pedals from a single 24V power source.

- Isolation: Five (5) individual custom transformers, one per channel, for clean and consistent power.
- Chassis: Lightweight and rugged anodized midnight blue aluminum.
- Included Cables: Five (5) 2.1mm x 5.5mm pedal cables (18” long, right angle to right angle connectors), one (1) IEC cable (region-specific), one (1) EIAJ-05 power adapter cable.
- Mounting Hardware: Two (2) #4 3/8” wide pan head screws for mounting.
Usage Features:
- Pedal Connection: Connects to up to five DC pedals using the included 5.5mm x 2.1mm pedal cables.
- Output Versatility:
- Three fixed 9V outputs are ideal for standard 9V pedals, providing a generous 500mA of current per output.
- Two adjustable outputs offer flexibility for pedals requiring higher voltages (12V or 18V) or for optimizing current draw. Users must ensure these are set to 9V for Strymon pedals or other pedals requiring 9V.
- LED Indicators: Each output features an LED that illuminates green when a pedal cable is plugged in and receiving power. The LED turns off if the cable is unplugged or if the current draw exceeds the maximum available for that output, providing a quick visual diagnostic tool.
- Expandability (24V THRU Jack): The Ojai R30 is part of a modular power distribution system. Additional Ojai units (sold separately) can be linked via the 24V THRU jack to expand the number of available outputs. This allows for powering a large number of pedals (up to 35 with 7 linked Ojai units) from a single 24V power adapter. It can also be linked with a Strymon Zuma power supply for ultimate power and flexibility.
- Mounting Options: Features built-in threaded hardware for easy mounting to the top or bottom of most pedalboards. A drill template is provided for precise installation.
- Worldwide Compatibility: The included PS-124 power adapter supports 100-240V AC input, making the Ojai R30 suitable for international touring without the need for voltage converters.
- Low Profile Design: Its compact and ultra-low-profile design allows it to fit under most pedalboards, saving space and maintaining a tidy setup.
Maintenance Features:
- Robust Construction: The lightweight and rugged anodized midnight blue aluminum chassis ensures durability and protection for internal components, reducing the need for frequent repairs due to physical damage.
- Isolated Outputs: The individual isolation transformers for each output contribute to the longevity of connected pedals by protecting them from power fluctuations and noise, which can sometimes lead to premature wear or malfunction.
- Diagnostic LEDs: The LED indicators on each output serve as a basic diagnostic tool, allowing users to quickly identify if an output is active or if a pedal is drawing too much current, which can help in troubleshooting and preventing potential damage to pedals or the power supply.
- Warranty: Strymon offers a five (5) year limited warranty from the original date of purchase (when bought new from an authorized dealer in the USA or Canada) against defects in material and workmanship. This provides peace of mind and covers potential manufacturing issues.
- Support Resources: Strymon provides online support resources (strymon.net/support/ojai-r30) and email support (support@strymon.net) for setup, connections, power, and mounting, facilitating user maintenance and troubleshooting.
- Designed and Built in the USA: This often implies a higher standard of quality control and access to repair services, should they be needed.
