The Ultimate All-in-One Portable PA System

The two lightweight speakers and a detachable mixer, along with one pair of speaker cables and a power cord, combine into a compact package that provides the kind of portability that no roadie would ever dare to dream of.

Fast and easy set-up

With its intuitive, simple design, STAGEPAS can be set up and ready to go in a matter of seconds. Even users with no PA operation experience will be able to produce high-quality sound in under a minute.

A PA for any occasion

Flexible enough to be used in a truly impressive range of environments and applications, STAGEPAS systems can be set up in a variety of PA and monitoring configurations.

Bluetooth Audio

Equipped with Bluetooth input for wireless audio streaming from smartphones or tablets, the STAGEPAS 400BT lets you seamlessly play backing tracks for gigs, or set the tone of parties, conferences, or events with the audio playback of your choice.

SPX digital reverb

One knob gives you access to four different high-quality reverb settings, perfect for vocals and acoustic instruments. Simply turn the knob to change the reverb type and time, and then you’re ready to apply just the right amount of high-resolution effect to each channel.

1-Knob Master EQ

This new function gives you instant mastery of your mix, allowing you to match your sound to your surroundings. Simply turn the knob to optimize the EQ for speaking engagements, musical performances, or just to kick in more bass; getting your sound right has never been so easy.

Feedback suppressor

Avoid the uncomfortable feedback that plagues so many sound reinforcement novices and professionals alike. Usually found only on high-end gear, this intelligent function removes feedback automatically with the push of a button, giving you a clear, professional sound.

Channel EQ

Assign detailed EQ settings to each channel for precise management of your final sound. Great sounding 2-band EQ on the STAGEPAS 400BT makes setup easy and precise.

Hi-Z switch

Connect electro-acoustic guitars and basses to enjoy high-quality performance with low distortion. Passive pickup instruments can be connected hassle-free, without a DI box.

Switchable stereo/mono inputs

A versatile new feature that allows you to transform each stereo channel input into two independent mono inputs, giving you the flexibility to adapt to the needs of a broad range of performance requirements.

Phantom power

Connect condenser microphones directly to STAGEPAS to get the best sound quality possible. Phantom power also means you won’t have to worry about DI boxes losing their charge during a performance.

Reverb footswitch

For hands-free control of your reverb, connecting an optional footswitch allows you to turn the reverb on and off instantly – perfect for MC-ing events or speaking during solo performances.

Monitor out

Expand your front-of-house system or set up a monitoring system by using the STAGEPAS together with other powered speakers such as our DBR, DXR and DSR powered speaker lines.

Subwoofer out

Add more low-end to your system by connecting a powered subwoofer such as the Yamaha DXS Series. Simply plugging in a subwoofer will assign a high-pass filter to the STAGEPAS speakers automatically.

More power. More possibilities

Delivering 400 watts of power, the STAGEPAS 400BT offers a major boost in performance, allowing you to meet the demands of a wider range of situations.

Same sonic experience throughout a wider coverage area

For use in larger spaces with a sizable audience, STAGEPAS is capable of delivering consistent high-quality sound throughout a greater coverage area than ever before with custom-designed speaker components that ensure the entire audience shares the same sonic experience.

Intelligent DSP for peak performance that lasts

STAGEPAS utilises digital signal processing (DSP) to consistently produce high-quality, distortionfree sound at any volume level, whether you’re giving a business presentation or cutting loose in a club. What’s more, our intelligent DSP incorporates the use of advanced limiter circuits to protect vital STAGEPAS components, ensuring that you get the most out of your gear for years to come.
