Art Pro Audio CleanBOX II - Hum Eliminator

I read a few reviews of this hum elminator which were generally positive so I took the plunge and bought one. I have a few hum issues with my guitar rig, pedal board, etc. The unit reduces the volume of the guitar signal by at least a half, if not more, killing tone and making is almost unable to drive a valve amp. I then tried it after the pedal board, turing the output volume of the pedals up to try and boost the signal enough to try and get a reasonable signal going into the amp. Whilst that did help a bit, the tone is still all but destroyed. I can see this unit would be very useful for some applicaitons and some audio equipment so I'm going to keep it. The one thing it is not good for is a guitar rig.

This box is great. It eliminated the hum from my audio interface/ monitors. I used to use a 2 way DI box (2 channel with ground lift) for years and was fed up replacing batteries every so often. Now I will just let this sit... I was contemplating buying a new interface but now I'm glad I bought this as its much cheaper. This is only for ground loops... If your having problems with humming (not ground loop) this might not be ideal for your situation. Do the research!

So I purchased one of these units and was massively disappointed once it was connected between a Beringer Interface and a Pair of Alesis Studio monitors.Remove noise? No it more Increased the noise almost acting like an amplifier, I used all balanced cables which made absolutely no difference just an increased horrid noise so it was disconnected and the sound was greatly improved?OK still have this buzzing noise and some hiss which I am sure is down to the Beringer Interface anyway cannot get rid of it.Turning down the gain is not so much the answer as a lot of the sustain the guitar needs i lost by doing that.I really do not want to buy another interface as Its likely many of the interfaces won't be much different.There maybe nothing wrong with this box but soon as I know I will report back what was exactly causing this noise.New balanced cables fitted absolutely no difference.

I bought this because my studio montiors and my Scarlett 2i2 were buzzing when I plugged into a different outlet.After a solid 2 weeks of frustrated, mood altering testing... I went with this as a last purchase, given I didn't want the extra cordage an a big box. Well, it WORKS!HumX didn't work. Updating drivers didn't work. Different outlets didn't work. It wasn't a coil whine either.It was clear to me it was a ground loop when I unplugged my laptop from power and everything worked great.Now with my PC, everything sounds perfect!

E' arrivato in tempo record (se non ricordo male dall'Inghilterra) e, cosa ancor più gradita, si è rivelato efficacissimo per eliminare il rumore generato dal mio ampli valvolare per chitarra (Koch Twintone) quando interfacciato con una pedaliera digitale (Fractal Audio FX8). Qui potete vederlo all'opera: [...] non sono io, ma il rumore è identico a quello che avevo io, come identico è l'effetto di silenziamento. Non ho notato altri influssi sul suono.

Does not require a power source!Easy to set up and use!Reduced but did not eliminate the buzzing in my studio monitors which seems related to power fluctuations in my gpu.

Ilk prodotto esegue egregiamente il suo lavoro (uscita da scheda audio verso mixer) dove avevo un segnale di hum. Avendo un simile segnale ho provato il box tra ampli e casse ma non ha dato i risultati sperati, anzi distorcendo il segnale. Lo ritengo però un acquisto molto valido.

Worked great to remove ground noise in my setup using a Mac Mini to record two channels of audio off my sound board at church. Ignore the reviews of people using it for their guitars, that is not the main purpose of this device. If you have a guitar and ground issues connecting to a sound system, use a direct box and minimize the length of unbalanced TS 1/4" cables. The intent of this device is to be used with balanced cables on both sides. When used for those situations it is perfect for the job and the lowest price tool for the job!
