  For the price it is actually a 5 star product, but it could easy be made better.
  
  I use this filter for a 3 way horn system, LCR in a hometheater, with 8 outputs i am almost there.
  
  Bugs:
  It looses the USB connection to a windows PC, replug it and you are good to go.
  More serously, if you set the high pass filter to defeat, there is still a filter function present, so set the filter function to 6dB/octave, and then Defeat for best case scenario. I could not grasp why my speakers suddenly rolled of sooner with this component.
  
  Be carefull with the link function it copies settings, so if you linc a tweeter to a sub/midrange setting it could be last tweet... It is a smart function when you want a stereo setup or other speakers with same settings.
  
  There is no LR 48dB/octave settings, 24dB/octave is max.
  
  What i miss most is the posibilty of importing PEQ filters, that is a manual proces with this device.
  
  There is a bit of noise issues, it is better in some aspect than the ballanced minidsp...but in my horn system with 110dB sensitivity it is quit audible...It helps alot to connect unused RCA terminals with a cable to your amp, that lowers the humm noise by 6dB or so...
  
  For the price it is a great product, nothing on the market comes close, and for most people it is plenty good. I think the humming issue will not be audible for most people, and maybe i need to check for better RCA cables....

  For 180 EUR it is hard to beat!
  
  Is it perfect? No, not by any means...
  
  The iOS app is more or less useless on an iPhone SE so if you don't have the need to switch streaming on/off or setting different profiles, there is no point buying the Bluetooth dongle. I need to set different profiles for driving alone and for having kids back in the car so that is what I will use it for.
  
  The Windows app is OK, but it would have been nice to see live input levels and I would prefer to be able to disable both streaming and volume control so that it can't be set by the iOS app. I want to calibrate my system and then it should stay exactly as I intended.
  
  It is a shame the Dayton Audio haven't continued to develop and improve the apps. Both the iOS and the Windows version are quite old. The iOS app design is so poor that I can't even place my fingers on the correct control, it is also very difficult to adjust the sliders due to the small scale. Why not allow me to click one channels and be able to enter filter parameters in a simple way?
  
  The Windows user interface is, however, quite clear and it is simple enough to do the adjustments I need to do.
  
  The wiring harness is very tiny and I would prefer to have a separate plug for power and speakers (I'm using RCA input). Rather than an inline fuse holder, I would like to have seen a fuse in the case.
  
  The general build quality seems good and RCA connectors also seems of good quality. The mounting flanges could definitely be a bit larger or ideally integrated in the case.
  
  Sound wise, I can't really review it yet since I want to play around with the Windows software a bit more before doing some actual tuning. I haven't had any problems with hum or noise as others have reported so at least it hasn't made my system sound worse!. (I'm not using the remote control which some believe is the problem.)
  
  Conclusion: Worth the money, but be aware of its shortcomings!

  This DSP has a good amount of options, pretty much everything you could need for a complete car install or stereo home system. The build quality is also good. The bluetooth accessory is worth it, makes it easier to tune, especially in car. I would give it 5 stars, but the reason I'm knocking off a star I installed this in my car, and it had sent so much alternator whine through my speakers it was crazy. So if you have the same problem, what you have to do is buy something like a CUI PYBE20-Q24-S12-T, which will isolate the power coming into the unit. There is also a "pop" sound on your speakers when it turns on and off, which can be fixed with delay circuits. With these additions it really is a great DSP, but I feel like it should have come with them, or at least be available as extras, I had to figure this all out for myself, it would have been a better experience if I hadn't had to.

  Das Gerät funktioniert einwandfrei.
  Es gibt einem viele Möglichkeiten Boxen im Heimbereich aktiv zu nutzen.Der Netzteiladapter ist leider Schrott.Und der Bluetooth-Adapter ist im Verhältnis zum Gerät viel zu teuer.

  Werkt helemaal zoals ik had gehoopt twee weg los voor aangestuurd(tweeters en Mids) , kickbass in de deuren(2x6.5 subs stereo) en lage subs (2x 12"mono)achterin alles
  Klinkt geweldig en werkt makkelijk via een laptop

  my uk based company Stylz Kustom has purchased many of these processors for a multitude of different types of car audio projects,and for a budget processor it punches way above its pricetag!<br />
  the software is very easy to use,i would recommend using a laptop for the initial set up as its only 2 pages,the very handy app for phone or tablet "tweaking" after is a big selling point,along with the dual master bluetooth.<br />
  Overall its a good solution for my customers and not overly complicated,if its your first processor.<br />

  After experimenting with modifying analog loudspeaker filters in my high end speakers using expensive capacitors and coils, this DSP came as a beautiful surprise. No matter how good the components in your filter, the DSP simply sounds better. Much better. The old analog speaker filter was the bottleneck, at least in my system (Rotel RSP-1098, Rotel RMB-1095, Rotel RB-1090, Vandamme 55 low cap interlinks, Supra Ply 3.4s, tuned Marantz NA-8005 media player). I strongly suspect this applies to audio systems in general, especially with standard grade filter components. I highly recommend this DSP!

  Sehr empfehlenswerter Soundprozessor.
  Von der Haptik bis hin zur PC-Software als auch APP. Programmierung sehr einfach und intuitiv. Kleines erstes Setup aus Zuspieler, Verstärker und Lautsprecher aufgebaut. Software und APP auf Samsung Tablet installiert. Und los ging's mit der einfachen Bedienung. Klang des DSPs ist TOP! Sehr erfreulich, der DSP ist absolut rauschfrei. In den kommenden Tagen baue ich den DSP in meinen PKW ein und Berichte dann weiter.
  
  Bis jetzt viel Kaufempfehlung und 5 Sterne.
  
  Mein Huawei P10 Lite mag sich nicht über Bluetooth koppeln. Das liegt definitiv nicht am DSP! Dies ist ein bekanntes Huawei Problem. Daher auch keine Abzüge bei meiner Bewertung.
