A balanced bargain
MuteMike, 08.06.2020
I've got to say I'm really impressed by this unit. Great value for money. I have used it in a 2 way DIY loudspeaker, and I've also used it to fine tune 2 pairs of loudspeakers in a recording studio.

I'll break down my thoughts...

The bad:
No on/off switch
Power light is too bright (blue)
Input headroom is not forgiving
Thomann's freebie included EU/UK adaptor doesn't actually fit with this PSU shape

The good:
nice form factor - useful holes to screw in place
Low noise (balanced in & out)
Software is easy and powerful
Excellent filters & EQ
Save and load your work
4 ins AND outs
A variety of useful processing
Works as a sine,white,pink noise generator

It seems to me that this unit is offering performance that you won't find anywhere else at this price point. This is a fantastic digital crossover, I'm getting better results than I was with a pricey passive crossover.

I am currently using this as a tool in my studio to minimise speaker/room inaccuracies. It's 4 channel meaning you can send it both your stereo main and mini feed, EQ each pair of speakers separately to remove any issues and even apply a limiter if you'd like, then you can mix without having to make allowances for your speakers/room.

I have been so curious about Sonarworks, however, my TDM Pro Tools HD system is way too old to support such software. This device is a really nice workaround for anyone using an old rig or an analogue mixing console. Although I would love to see an updated model with more headroom, an on/off switch and a more subtle light!

Thanks Thomann for this great device. The delivery for this item did take ages, but it was so worth the wait.

Great little unit!
Karmo7, 08.03.2020
I have two of them! Bought one to adjust my living room sound system and other we use at church as a PA processor.
Theres is a compressor/limiter, one 7 band parametric eq + LPF and HPF for every OUTPUT.
No processing but gate and phase flip for input channel.
EQs can be linked, for example, linking left and right eq, one follows another instantly, no need for copying settings.
Crossover works nice, different slopes can be selected.
Matrix/routing is very easily understandable.
PC software works well for me, didn't have any issues. You definitely need Windows computer to access this unit. No support for Apple or other os system.

This unit uses 12v power supply and this got me wondering... maybe I should buy a third one for my car?

Top crossover
Padarinho, 21.02.2020
Best dsp i ever seen. You can do with dsp whatever you want (crossover,limiter,compressor...) Very easy to conect and use it.I use it for limiter and crossover for 2 passive speakers and 2 passive subwoofers.
