The Perfect All-in-One Solution for Sound Reinforcement - STAGEPAS 400BT!
When mobile live-sound setups are required, there’s no better choice than STAGEPAS. With impressive power and sound quality, intuitive controls, and a comprehensive yet flexible feature set, this all-in-one PA system delivers the complete solution — now with wireless Bluetooth audio streaming. It turns any environment into your stage.
The STAGEPAS PA system is easy to take anywhere thanks to its compact dimensions and low weight. Two included speaker cables and the power cable link the lightweight speakers and the removable mixer unit into a compact system. It stays so portable that roadies will be jealous. Despite its size, you get consistent coverage even across large areas. STAGEPAS projects its high-quality sound very evenly over a wider area, which benefits larger events with more attendees in particular. Specially developed components ensure that the listening experience is the same for every guest.
Yamaha STAGEPAS is also an ideal sound solution for meetings and presentations. The solid power, great sound, and easy setup take your talks to a professional level.
Quick and Easy Setup
Thanks to its intuitive, straightforward design, the STAGEPAS system can be set up and ready to go in seconds. Even without much PA know-how, everything you need for first-class sound can be in place within a minute.
A PA for Every Occasion
STAGEPAS is flexible enough to handle a surprisingly wide range of tasks and situations. The system is just as suitable for artist monitoring as it is for audience reinforcement.

Intelligent DSP Enables Top Performance
STAGEPAS uses a digital signal processor (DSP) to deliver high-quality, low-distortion sound at any volume level—whether you’re running a corporate presentation or rocking a club. Yamaha’s intelligent DSP employs advanced limiter functions that protect key STAGEPAS components from damage. That means you’ll still get the most out of your system years from now.
High-Resolution SPX Digital Reverb
With a single control you can choose between four different high-quality reverb settings—perfect for vocals and instruments. Use the convenient combination control to change the reverb type and decay time, then precisely dial in the right amount of effect for each channel.
One-Knob Master EQ
This new feature gives you effortless command over your mix. It lets you tailor the sound perfectly to the PA situation. Simply turn one control to smoothly set the master EQ for either speech applications or music concerts. An additional control range adds extra punch via added bass. It’s never been easier to produce an optimal master sound.
Feedback Suppression
The feedback suppression prevents unpleasant howling that can trouble both PA novices and professionals. This intelligent feature is usually only found on high-end gear. It can automatically remove feedback at the push of a single button, giving you a clear, professional sound in any situation.

Flexible Connections
With ten and eight channels respectively, the STAGEPAS 400BT and 600BT offer versatile connectivity and full-featured channel configurations. The systems can also be expanded easily to meet the growing demands of different applications and environments.
Bluetooth Wireless Audio Streaming
The STAGEPAS-BT models include a Bluetooth input for wireless audio streaming from smartphones or tablets. That makes live shows, parties, conferences, and other events easy to support with appropriate sound reinforcement.
Lightweight Aluminum Speaker Stands
Stable support for PA speakers doesn’t have to be expensive. The new Pronomic speaker stands are the best proof. Their sturdy tripod construction gives secure support for your speakers whether on stage, in the rehearsal room, or in clubs. Various adjustment options guarantee maximum flexibility in positioning, and an additional metal splint secured with a nylon strap prevents accidental speaker drops.
Pronomic Bag for 2x Speaker Stands or Lighting Stands
Live use puts the toughest demands on gear. Stands in particular often suffer wear and tear. The new Pronomic carrying bag protects your stands—and the rest of your equipment—from transport scratches! The Pronomic stand bag is made from water-repellent, tear-resistant material and offers optimal protection. A sturdy zipper and reinforced carrying strap provide comfortable transport. The Pronomic BLT-125 stand bag fits two speaker or lighting stands and includes an integrated divider.
