Q: What devices is the Roland PSB-120 power supply compatible with?

The Roland PSB-120 is designed for a wide range of Roland devices that require a 9V DC power supply with a current draw of up to 2000mA. It features a center-negative polarity, which is standard for many Roland pedals, keyboards, and other electronic instruments. Always check your specific device's power requirements to ensure proper compatibility and safe operation.

Q: Can I use the PSB-120 with devices that require less than 2000mA?

Yes, absolutely. The PSB-120 provides up to 2000mA of current, but your device will only draw the amount of current it needs. For example, if your Roland pedal requires 9V DC and 500mA, the PSB-120 will safely supply that amount without issue, leaving plenty of headroom and ensuring stable power.

Q: What are the voltage and current specifications of the PSB-120?

The Roland PSB-120 delivers a stable 9V DC output with a maximum current of 2000mA (2 Amps). It features a universal input voltage range of 100-240V AC, 50-60Hz, making it suitable for international use with the appropriate plug adapter. The polarity is center-negative (tip: negative, sleeve: positive).

Q: How do I know if the PSB-120 has the correct polarity for my device?

The PSB-120 has a center-negative polarity (tip is negative, sleeve is positive). Most Roland devices use this standard. You should always check the power input jack or the owner's manual of your specific device for its required voltage, current, and polarity to ensure safe and correct operation. Using the wrong polarity can damage your equipment.

Need additional help?

Q: Can I use this power supply with non-Roland equipment?

While the PSB-120 is designed for Roland products, it can power other brands' devices if they require 9V DC, draw 2000mA or less, and specifically use a center-negative polarity. It's crucial to verify all three specifications for your non-Roland gear to prevent damage. When in doubt, consult a Sweetwater Sales Engineer for personalized gear advice.

As usual the products I received from Sweetwater are always up to standard! Same as the original! And it's never a problem! And the 2-year warranty is the best! Only at Sweetwater babe, where musicians get treated like kings! The only place to shop for great musical equipment and the best warranty ever! Unfortunately, my product was delivered and someone took the package off my door steps, so I notified Sweetwater and with no problem the product was replaced. I thank you guys as Sweetwater, Marshall,Doug and Robb with 2 bb's! Im back up and running!

I'm lazy, so don't like unplugging the power adaptor before I head out for rehearsal. So, I bought a second power adaptor so I can leave one at home and the other in the bag, ready for rehearsal. This works like a charm. Exactly what I needed for my Boss GT 1000.

Experienced a little water damage in the studio a few months back. Any power supply laying on the floor was damaged. I was happy to find the exact replacement (at a great price) I needed to get my practice kit up and running until everything else can be returned to normal.

Purchased as a backup and works as advertised.

When it comes to the music industry, there are many resources to utilize for what you're looking for but few are trustworthy & none are as professional as Tyler and crew at Sweetwater.

Simply put, modern electronic music wouldn't exist without Roland. Many of the electronic musicians here at Sweetwater cut our teeth on TR Rhythm machines and fondly remember programming our first TB-303s. We owe a good part of our careers to this amazing and innovative company. It's been fun to watch and grow right alongside Roland, as they've introduced wave after wave of revolutionary keyboards, digital pianos, and more. For example, Roland's V-Drum Kits continuously redefine the possibilities of electronic drums, beginning with SuperNATURAL technology to the latest Prismatic Sound Modeling. We're huge fans, and we'd love to tell you all about them. Whether you want a pocket-sized synth or a cutting-edge video mixer, if Roland makes it, then Sweetwater is 100% behind it.
