Yamaha STAGEPAS400BT — 400W Portable PA System with Bluetooth

The Yamaha STAGEPAS400BT is a 400-watt portable PA system for musicians, presenters, and event hosts who need professional sound in a single carry-friendly package. Two 8" two-way speakers pair with a detachable 8-channel powered mixer to deliver clean, full-range audio for audiences of roughly 150–180 people. Mobile performers seeking studio-grade DSP, Bluetooth streaming, and fast setup will appreciate its flexibility.

What sets the STAGEPAS400BT apart

Advanced DSP developed by Yamaha runs limiter circuits that safeguard the amplifier and drivers at high SPL, and the one-button feedback suppressor automatically removes ringing. A 1-Knob Master EQ with virtual bass boost and SPX digital reverbs allow even non-technical users to achieve polished sound in seconds.

Power and speaker configuration

Built around a Class-D bi-amped design, the system delivers 400 watts total split between two cabinets, each pairing an 8" woofer with a 1" voice coil compression driver.

• Total Power Output: 400 W (200 W + 200 W) — true stereo coverage.
• LF Driver: 8" woofer — handles bass and low-mid warmth for vocals and acoustic instruments across the mix.
• This model's HF driver ensures crisp highs thanks to its 1" voice coil compression driver.

8-channel detachable mixer with Bluetooth

With a detachable 8-channel powered mixer, the setup includes four mono mic/line inputs, four mono or two stereo line inputs, Hi-Z switching, and phantom power, plus Bluetooth wireless audio streaming for backing tracks.

• Mixer Configuration: 8 channels (4 mono mic/line + 4 mono / 2 stereo line) — covers full bands, duos, and presenters.
• Use Bluetooth audio streaming to play backing tracks or break music without a cable.
• Channel EQ: 2-band per channel — quick tonal shaping for each source.

Effects, feedback control, and system expansion

SPX-derived digital reverbs deliver four high-resolution types with parameter control, while the onboard feedback suppressor removes problem frequencies at the press of a button.

• Reverb Engine: SPX digital reverb, 4 types with parameter control — pro-grade vocal and instrument ambience.
• Feedback Control: One-button intelligent feedback suppressor — eliminates squeal automatically.
• The system offers Monitor and Subwoofer outputs, so you can pair it with Yamaha DBR/DXR/DSR tops and DXS subs.

Who should choose the STAGEPAS400BT

The STAGEPAS400BT is a strong fit for solo acoustic musicians, mobile DJs, small bands, houses of worship, schools, and corporate presenters needing a self-contained sound system that fits in a car. Its 400-watt output covers audiences up to roughly 180 people in pubs, clubs, and conference rooms. Bluetooth streaming, phantom-powered mic inputs, and Hi-Z guitar channels let a single performer run vocals, an acoustic-electric guitar, and backing tracks from one mixer.

The STAGEPAS legacy

The STAGEPAS series has served as Yamaha's flagship all-in-one portable PA line for two decades, with the brand celebrating its 20th anniversary in 2025. Combining Yamaha's professional DSP heritage with Bluetooth connectivity in a single carry-ready package, the STAGEPAS400BT brings these strengths to today's mobile performers.
