Complementing the boost in performance, the addition of iPod/ iPhone connectivity, SPX digital reverbs, an onboard feedback suppressor and more versatile EQ, has improved functionality and ease of use considerably, allowing STAGEPAS to meet the demands of a much wider range of applications and users.

The Ultimate All-in-One Portable PA System

The new STAGEPAS 400i and 600i are complete, all-in-one sound solutions that are extremely portable and easy to set up, allowing users to instantly add high quality sound reinforcement to virtually any environment.

New Mixer Features for a Streamlined Set-up

The new STAGEPAS was designed to offer high quality sound, simply and quickly to let you do what you do best. Whether you're giving a speech or playing a gig, STAGEPAS is equipped with intelligent new features that provide simple, intuitive control of optimized settings, making it easy to dial in your perfect sound in a matter of seconds.

A Flexible Mixer with Improved Functionality

Equipped with 10 channels or 8 channels respectively, the STAGEPAS 600i and 400i offer versatile connectivity, comprehensive channel functions, and seamless expandability that meet the growing demands of a wider range of applications and environments.

Higher Power Output, Higher Sound Quality, Higher Reliability

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.

- 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 Yamaha’s DXR lineup.

- Subwoofer out
Add more bottom 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 680 and 400 watts of power respectively, the STAGEPAS 600i and 400i offer a major boost in performance, allowing you to meet the demands of a wider range of situations.

New speaker design for an increased coverage area

The new speaker design lets you deliver evenly-distributed, high-quality sound to a greater coverage area, so that the entire audience shares the same sonic experience.

Intelligent DSP for peak performance that lasts

STAGEPAS utilizes digital signal processing (DSP) to offer the consistently high-quality, distortion-free sound at any volume level, whether you're giving a business presentation or cutting loose in a club. What’s more, Yamaha’s 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.

"Best In Class & In A Class By Itself"
Pros: Expandable,Compact,Easy To Use,Best in class,Lightweight,Versatile,Durable,Clear Sound
Cons: No Sweepable Channel Mid

Due to serious injury & permanent disability, I'm never hauling heavy gear again & it seemed my solo gigging nights were over. At festivals & venues with "in house," I've played thru many small/light systems - yes, even those very expensive "breakthroughs." I could never emulate my sound which I have carefully crafted through many years as a pro. 12" speakers were the minimum I required. Suddenly, I had no choice but to find a much lighter one - or hire a roadie (yea right). My search began.

I played my acoustic and sang thru every system I could find, A & B'ing all possible. Most were brutal, with a sound & FEELING akin to playing in or through a tin can & I was losing hope. I'd used Yamaha's earlier StagePas 300 & 500 and they came close but no cigar - with few but unacceptable limitations and very unlike Yamaha - terrible reverb with no ext. loop. Just as I began to loose hope, feeling a sound compromise was inevitable I discovered the new 400i and solo nights ahead were saved!

Several brands make similarly sized systems, however size is where the similarities begin and end. Yamaha's new StagePas PA's brilliance stands way out from every system similar in size/weight - regardless of price. They're brilliantly designed with nothing tinny about them, just warm, smooth clarity from guitar & vocals with shocking volume capability. The addition of outs for both powered monitors and a sub make for awesome versatility. At a showcase I hosted I added a 12" powered monitor and everyone was amazed. Even a loud duo with a keyboard was crystal clear. If you're in need of a compact, light, easy to use PA, I urge you to try the 400 or 600i before spending more than twice as much. You'll be glad you did.

As a producer as well as performer I'm extremely critical of sound quality and if there's a better system in this class I haven't heard it. In addition to solo, I work with several combo's including a 5 piece blues & rock band that quickly discovered the 400i serves as an outstanding addition or core of a large room system. We replaced heavy powered monitors with the StagePas 400i, making both setup and SOUND better.

Over 30 years, I've used tons of gear and always been pleased with most Yamaha gear, now I thank them for making it possible for me to keep working as a solo without compromising my sound. The only aspect I feel is a slight "con" is lack of sweepable mids for each channel or at least a 3 band system EQ. It's not a major issue and can be remedied easily by using a pre-amp with EQ. It's also worth noting that unlike most powered mixers there is virtually no hum from the amps when using the stereo record out. This is a long review and plenty of praise remains - Thank You YAMAHA!

System sounds great & super portable.
Pros: Easy To Use,Clear Sound,Versatile,Lightweight,Compact
Cons: Short Speaker Cables

The system was purchased by our church. I chose it due to it being so lightweight and portable. It works great, sounds great, easy to set up, and looks good. I wish the speaker cables were longer, but we manage with what it has and we have longer speaker cables if we need them.
We primarily use this every Sunday in the summer for our outdoor worship service under a picnic pavilion and it sounds great! We plan to use it for other outdoor events in the future as they come up and think this is a great system due to being so portable. We are happy with our purchase of this system.
