Yamaha Stagepas 400BT Portable PA System

The Yamaha Stagepas 400BT is a completely all-in-one portable PA system that offers outstanding sound quality and a compact, lightweight design that can be transported with ease. The Stagepas 400BT consists of two passive 8'' speakers which deliver high-resolution audio reproduction and a detachable 8 channel 400W powered mixer. The new 400BT system is equipped Bluetooth connectivity which allows you to wirelessly stream audio from smartphones and tablets, ideal for applications that require high-quality background music. Complete with Yamaha's state-of-the-art DSP and extensive onboard functions, the Stagepas 400BT portable system provides reliability and versatility that is perfect for live performances, conferences, gigging musicians, parties and more.

The perfect blend of power and portability

PA systems have a reputation for being big, bulky, and difficult to manage. The Yamaha Stagepas 400BT changes all of that. With a compact design that's light enough to be carried by hand, this all-in-one portable PA system lets you take your sound with you wherever you go.

The Stagepas 400BT consists of two lightweight speakers complete with a detachable mixer. The package also comes complete with a pair of speaker cables and a power cord that can be conveniently stored in the rear compartment of one speaker. Combined with the system's intuitive design, you have everything you need to be set up and ready to go in an instant.

With 400W of power on tap, this compact system is capable of producing a massive SPL of 125dB. For comparison, that's louder than the typical noise levels recorded at the front row of a rock concert. With the Stagepas 400BT, you know you're going to be heard, and all without having to break your back just getting it to the venue...

Versatile connectivity and intuitive controls

With eight channels at your disposal, simply connect your equipment and enjoy high-quality performance. Channels 1 to 4 let you connect microphones, including condenser mics, or line-level devices. When it comes to instruments, you can engage the integrated Hi-Z switch on channel 4, letting you connect electric guitars, bass guitars or even electro-acoustic guitars.

The Stagepas 400BT also features two stereo channels. These can be quickly and easily switched between stereo and mono mode, giving you plenty of flexibility for any situation. Thanks to the dedicated Monitor and Subwoofer outputs, you're able to expand the system with additional powered speakers, stage monitors, and even powered subwoofers. Whether you have previous PA experience or not, the Stagepas system has been built so that you can pump out phenomenal sound in seconds.

Seamless Bluetooth® audio streaming

Smartphones and tablets have become an integral part of our lives. That's why the Stagepas 400BT lets you wirelessly stream audio straight from your device to your PA system. No matter what the event or situation may be, you can control the audio playback from your smartphone or tablet, whilst that incredible Stagepas sound ensures that you're heard with absolute clarity.

Intelligent processing for stunning sound

Consistent performance, every single night. The Yamaha Stagepas 400BT utilises intelligent digital signal processing to ensure that no matter what you're playing, you'll always sound your best. The DSP gives you high quality sound that's free from distortion at any volume level. Plus, with advanced limiter circuitry, your Stagepas components will remain safe for years to come.

The Stagepas 400BT also features Yamaha's powerful 1-Knob Master EQ™, letting you instantly optimise the sound of your system for different applications. All with the simple turn of a control knob. Whether it's for Speech, Music, or that extra Bass Boost, the 1-Knob Master EQ™ makes sure that your system is set up to suit your needs.

There's also another control knob that can give your sound a huge impact. The SPX Digital Reverb knob lets you quickly and easily select between Hall, Plate, Room, and Echo algorithms. Split into four parts, the single knob provides you with intuitive selection and control of the reverb algorithms to add space and atmosphere to any sound.
