Overview

The Yamaha PX3 is a Class-D stereo power amplifier designed for professional audio applications. It delivers 300W per channel at 8 ohms and 500W per channel at 4 ohms, while being approximately 50% lighter than previous P-series models. The stainless steel chassis ensures durability for touring and fixed installations. Onboard features include D-Contour processing, a setup wizard, panel lock, and event logging, streamlining the workflow for sound engineers. Priced around ¥140,000 on Japan, it offers strong value in its class.

Connectivity & Compatibility

The PX3 accepts balanced audio via XLR/TRS combo jacks, making it compatible with mixers and audio interfaces. Outputs are on speakON-compatible terminals for passive speakers rated at 4 or 8 ohms. Optional expansion cards (sold separately) add Dante or analog input flexibility. Typical connected devices include passive PA speakers, monitor wedges, and installed sound systems. It is not designed for consumer hi-fi setups.

Product Info

The Yamaha PX3 is the entry-level model in the PX series, launched around 2016 and still in production. Warranty is typically one year (confirm with seller). Accessories are minimal: power cable and manual. Market positioning is entry-level professional. Compared to the higher-output PX5 and PX8, the PX3 suits small to medium venues. Its light weight is a key advantage for portable use.

Best Use Cases

Small venue sound engineers: 300W x 2ch covers 100-200 capacity rooms. Lightweight design eases load-in/out. Not sufficient for large halls or arenas. Mobile event crews: The 50% weight reduction significantly impacts transport and setup. D-Contour simplifies room compensation. For fixed installations where weight isn't a concern, cheaper alternatives may suffice. * System integrators for fixed installs: Stainless build and panel lock resist tampering and aging. Event logging aids troubleshooting. If networked audio (Dante) is required, an optional card must be added.
