Yamaha STAGEPAS 400BT Portable PA System

The Yamaha STAGEPAS 400i transforms coffee houses, school gymnasiums, church fellowship halls, and outdoor festivals into professional performance venues—no sound engineer required. This isn't a compromise PA for musicians who can't afford "real" sound reinforcement; it's a meticulously engineered 400-watt system that delivers the clarity, power, and flexibility that Wisconsin's working musicians, educators, and presenters demand from De Pere to Fond du Lac.

Yamaha's detachable 8-channel powered mixer provides genuine versatility: four mono/line inputs plus four switchable mono/stereo line inputs handle everything from solo singer-songwriters to full worship bands. Hi-Z inputs accept guitars and basses directly—essential for acoustic acts and solo performers working without pedal boards. Switchable phantom power supports condenser microphones for vocals, acoustic instruments, and podcasting applications.

High-quality 8" woofers and 1" voice coil compression drivers deliver 200 watts per side with remarkable definition across the frequency spectrum. Yamaha's 1-Knob Master EQ with virtual bass boost lets you quickly adapt to room acoustics without extensive sound check—critical when you're setting up in unfamiliar venues. High-resolution SPX digital reverbs (four types with parameter control) add professional polish to vocals and acoustic instruments without the muddy, metallic quality of budget effects processors.

Bluetooth audio streaming lets you run backing tracks or provide interlude music from your smartphone—perfect for solo performers, presenters, and wedding ceremony musicians. The onboard feedback suppressor actively identifies and eliminates feedback frequencies before they become problems, while monitor and subwoofer outputs allow system expansion as your needs grow. Optional reverb footswitch enables hands-free effect control during performance.
