the t.racks DSP 4x4 Mini

Obviamente por este precio, no es un producto para audifilicos. Sin embargo trae un montón de opciones muy fáciles de configurar, con un ordenador siempre, eso sí.
Con este cacharro, el micro de medición de behringer, un sub de coche, una etapa de coche y dos tops vieta de hace 20 años que me regalaron porque no los usaban; he conseguido un bastante, bastante cariñoso. A mi parecer, mejor que muchos equipos hifi, puede que incluso hiciese dudar a un denominado audifilico con los ojos vendados.
Ah, un fallito, tiene un poco de latencia, si lo usas para pinchar o tocar en directo lo notarás, un pelín molesto pero nada preocupante.

I say it straight away, I have used more DSPs in my career than I drank coffees and anything under hundreds of euros would have been a laugh in those days. But wanted something on a budget for the project studio, ran across this thing and I'm honestly surprised.

It's not perfect. The eg is soft and not particularly precise. The delays only come in steps of fractions of a millisecond and the software UI looks like, well, a typical German app from the 90s.

But none of that matters for this price! It was good enough to match up against measurements using SMAART and the result is pretty pleasant. The sound is on par with much more expensive units and it's versatile enough to deal with a typical stereo + sub woofer situation. Not sure I would recommend it for an surround sound work since the delay is simply not precise enough for properly tuning multiple sources to cinema level but for the home studio it's simply ground breaking.

Only one gripe I have is the software. It's really 90s blocky cheap windows stuff. These days things such as being able to increment values via mouse scroll, proper save dialogs or even being able to sync two channels together is almost standard. As both a programmer and audio engineer I think that it's pure laziness and lack of vision making software this old school these days. Fix that and this unit could become world famous and not just some obscure German home brand!

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.
