    Die Ware wurde schnell geliefert. Leider liegt kein deutsches Manual bei und es bedarf einiges an mehr Zeit, den DSP 408 einzustellen. Ansonsten sehr gutes Gerät!

    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.

    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....
