Yamaha P3500S Power Amplifier 350W

Condition: Excellent

The Yamaha P3500S is a serious professional power amplifier built for musicians, venues, DJs, churches, rehearsal spaces, and live-sound applications where dependable power matters. It delivers 350 watts per channel into 8 ohms and 450 watts per channel into 4 ohms, with 900 watts available in bridged 8-ohm operation. Yamaha equipped the P-Series with its EEEngine technology, designed to deliver high output while reducing power consumption and heat. With XLR and 1/4" TRS inputs, Speakon, binding-post and 1/4" outputs, stereo/parallel/bridge modes, filtering, protection circuitry, and a variable-speed cooling fan, this is a versatile 2U rackmount amp that was designed to work.

Yamaha is one of the most established names in professional music, with an artist roster that includes legendary players such as Billy Sheehan, John Patitucci, Dave Weckl, Nathan East, Steve Gadd, Peter Erskine, Joe Bonamassa, Mike Stern, and Lee Ritenour. These artists use various Yamaha instruments and equipment across the company's product lines—not necessarily this particular amplifier—but their association reflects the brand's long-standing presence at the professional level. The P3500S itself has earned a reputation as a straightforward, capable workhorse: substantial power, sensible engineering, excellent connectivity, and no gimmicks.

Yamaha has since discontinued the P-Series, making clean, properly functioning examples increasingly dependent on the used market. Whether you need power for passive mains, monitors, a rehearsal rig, mobile PA, or a permanent installation, the P3500S remains a very capable choice. If you've been looking for a proven Yamaha professional amplifier, this is an opportunity to add a well-engineered piece of pro-audio gear to your system—grab this one while it's available.

As shown in the pictures, there are a few scuffs and cosmetic blemishes on the unit (as is to be expected with a previously owned item). However, this unit has been tested and functions as intended.
