Overall Impression

A compact, mixer-equipped PA that keyboard players find convenient for gigs and home setups. Multiple commenters use the 400BT as an amp and small PA for keyboards like the Nord Stage 3, Roland FA08, Korg SV2, and Roland Juno D6. They value the onboard mixer with effects on channels 1-4, and one long-time Stagepas 300 owner saw the 400BT as a natural upgrade. Another liked the mixer function enough to wish the cabinets clipped together for single-unit carrying, similar to a Fender Passport.

Some keyboard-focused users found the sound reproduction fell short for critical use. One user paired the Stagepas 400i with a Nord Stage 3 and felt the speakers lacked a flat frequency response, not doing justice to the piano sounds, eventually switching to QSC K8.2 monitors. Another warned against pairing it with a CP88 at home, saying the speakers amplified resonant frequencies from the keyboard's rich samples, and noted the lack of a stereo XLR input and limited headroom, opting instead for Yamaha DBR10 speakers.

A handful of reliability, power, and connectivity complaints surfaced among users. One buyer reported the unit powering on briefly then cutting out, with Bluetooth no longer working either, despite being used lightly for under ten months. Another criticized the mains-only power design, wishing for 12V/solar compatibility. A separate user struggled to get Bluetooth discoverable on their device, and a Genos keyboard owner paired with the 600BT reported unclear sound.

Commenters describe it as a great, compact system for pairing with keyboards like the Nord Stage 3 and as a worthwhile upgrade from an older Stagepas 300 unit. Its all-in-one form factor suits small setups and rehearsals.

I've got the earlier Stagepas 300 which I bought about 15 years ago. It's a great PA, but it's getting old so I've decided to get a newer system. The 400BT looks ideal for me.

@RikHoward.

I got the 600 model. It's a great compact system and the sound quality is awesome but sometimes I could do with a bit more power (volume). They should make an 800BT or a 1000BT MODEL now that would be cool.

Great video. Just a couple of additional comments:\n- The OP is correct to use the CH1 and CH2 output for left and right stereo for his Nord keyboard; however, for users of other keyboards you may only have a keyboard jack socket available, and in this case you'll need to buy a cable with a stereo jack on one end for the keyboard, and two mono 1/4 inch jacks at the other. \n- On the Stagepas 400 and 600, you can use channel 5/6 as either stereo (two input jacks) or mono (top input jack only). Be sure to set the stereo/mono push button for the channel strip to the desired mode. \n- Also on the Stagepas 400 and 600, the internal effects are available for channels 1 to 4 only. So anything you plug into the remaining channel strips needs reverb added separately. This isn't a problem for most keyboards. In theory, you could plug the left and right mono plugs into channels 3 and 4, which would allow you to add effects, but you'd lose stereo positioning since there are no pan pots on the mixer. I've overcome this issue with my Stagepas 400BT by getting a separate stereo mixer with effects (Mackie MIX12FX), which I can plug into channel 5/6. This gives me a separate stereo sub-mix with effects at a reasonable price. Another option is the Behringer Xenyx 1202SFX.

A detailed comment explains that internal effects are available for channels 1 to 4, useful for adding reverb to keyboard or vocal signals directly through the mixer without external processors.

Frequently criticized

A 600BT owner wanted more power/volume at times, and another user noted the system lacks headroom compared to dedicated active speakers, suggesting output can be a constraint in demanding situations.

@fraterdeusestveritas2022

If you have a CP88 do not under any circumstance buy a stagepas for it. If you use it at home the speakers amplify all the resonant frequencies of the room from the CP88s very rich sample library. I found this out the hard way. You need active speakers with circuitry that prevents speaker resonance. Also the stagepas has no stereo xlr input and you'll lack headroom. I bought Yamaha DBR10s. They amplify the noise floor of the class D amplifiers but they do portray the richness of the sample library.

One user felt the Stagepas 400i's monitors lacked a flat frequency response and didn't do justice to Nord piano sounds, while another found it amplified resonant frequencies from a CP88's rich sample library, both eventually switching to separate active speakers.

@f.ziegler9950

Certainly, this is a big step upwards. You may experience, however, that you are not fully satisfied on the long run. I used my Stagepas 400i with a Nord Stage 3 and wasn't happy. The monitors were lacking a flat frequency response: They didn't do justice to the quality of the Nord piano sounds. I now use a pair of QSC K8.2 and am quiet happy - CP8 would be OK, too. There may be some other products at the price level of the Stagepas 400 which sound much more natural - neither them nor the more expensive have that nice mixing module of the Stagepas series, though.

One buyer described the unit powering on for only a couple seconds before shutting off, with Bluetooth also failing, after less than ten months of light use.

@le_Ach

Mine turns on but no sound anymore, the on indicator lights up for 2 seconds then turns off... even the bluetooth device doesn't turn on anymore.. when I press the phantom button it lights up but no sound. Used less than 10 times (less than an hour each time) what should I do? Reset? How? Bought 10 months ago. Thanks

A commenter criticized the system for requiring mains power, wishing for a 12V-compatible version that could run off a lithium battery and solar panel for portable use.

@Dream-Academy

Pathethic! It's mains power! If it's not battery operated you may as well plug in a full PA system! How about making it 12V Yamaha so we can run it forever off a 12 V lithium battery and a solar panel?
