## Questions & Answers

**Q: It would be a good idea to add the specifications of this product ... volts, mA, polarity, etc**
A: 9 volts DC (direct current) output. 500ma. Regulated. Tip negative. Sleeve positive. 3 meter cord. Status light flashes to indicate grounding problems. "Space saving" design compared to traditional adapters to allow multiple adapters to connect adjacent to each other on common outlet strips.

**Q: Is this genuine Boss/Roland product or 3rd party copy?**
A: The box says "Roland Corporation" and "Made in China". If this is a 3rd party copy how would I know? It sure looks like its genuine to me.

**Q: Will BossPSA-120S power Adapter   power Boss Digital Recorder MICRO BR  (requires 3v dc)**
A: It works on the Boss Roland BR-80 Portable Digital Recorder (http://smile.amazon.com/gp/product/B0052W4188/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1).

### ⭐⭐⭐⭐⭐ A great and reliable power supply.
*by S***X on 10 June 2026*

In my opinion, the “Boss PSA-120S Power Adapter” is an industry leader in on-the-floor or desktop pedalboard power supplies. I own several and have never had any noise or wire interference, and the power is stable all the time. I would recommend this adapter to everyone looking for an easy-to-use 9V power supply for their pedalboard units. Just don't try to power several units at once for a long gig.
