ART DTI 2-channel Hum Eliminator Reviews

It really does.

This Hum Eliminator does exactly what it says. It was as easy as plug-and-play. All thanks to Justin Dunn for helping us find exactly what we need.

I needed something to cut the hum from my monitor signal source to my IEM system. And pending on the venue this signal source can vary. This box, like all of the ART 'solution' products, is built like a tank and can be used in a variety of ways since it has two channels and accepts TRS, XLR and RCA. I tried all three options with my rig and for some reason the RCA circuit on the output side is the noticeably cleaner than the TRS outs. I'm not sure why that is but the hum is gone! This box should be in every electronic musician's toolbox.

We are actually using the ART DTI as a converter to go from XLR to 1/4 so that our streaming console can provide audio to our BMD Constellation 8k video mixer. It works flawlessly. I know it was the right choice for our setup and I would suggest it to anyone who needs to convert connectors instead of using a straight barrel converter.

Brendan Murphy is an outstanding sales engineer. He is extremely helpful and very knowledgeable. A pleasure to deal with and to assure success in tge proper equipment to order.

We were about 15 minutes from showtime at a new venue for us, (playing at one of the many marinas in our area), and still had a horrible hum in the lead singer's monitor. I had tried all of the usual fixes...changing cords, using a different outlet, power strip, etc... but nothing would get rid of the noise, and it was loud enough to make the monitor essentially unusable. Don't ask me why the noise wasn't also in the mains, or any of the other monitors. I don't know, but thankfully, all of those were fine.

Suffice to say, that electrical distribution at some marinas is a bit sketchy at best. There's a reason why they have those, "No swimming!! Risk of Electrocution!!" signs posted on the docks.

Anyway, I had literally just received the Art hum eliminator from Sweetwater a few hours earlier, and thought to myself, welp, we're gonna find out right now if this puppy really works. I hadn't even had a chance to read the instructions. But, since there are no controls on the unit, it is pretty much plug and play. Or in my case, plug and pray. It's either gonna work, or it's not.

I pulled it out of the box, and plugged the hum eliminator in line for the singer's monitor send (she has a Turbosound active monitor), and told the bass player to turn the monitor on. The bass player gave me an, "I don't believe it", kind of look, and said..."It is on"...and it was dead silent. I mean, not just a reduction in the hum, but no noise at all. Gone...and this was a loud hum.

The time, stress, and frustration this unit saved me at a new venue, and also saved us from starting late, really saved the day. It was absolutely worth the money I paid for the unit, just on this one gig alone.

I make no claim that it can take care of every hum problem, but it did this one, and did so in spectacular fashion. I'm sold.

Had a 60 cycle hum from a ground loop somewhere in my pedal board gadgets... Checked all grounds and determined I needed some sort of iso transformer... presented my dilemma to the Sweetwater sales engineers and as usual they came through. Hooked the ART DTi2 to the output of the pedal stream and NO MORE HUM... No degradation in bass frequency, signal or effects... This is has to be a definite, permanent, required addition for any rig...right alongside my Furman power distribution unit. Thank you again Sweetwater!

Everyone kept telling me a had a hum in system I but didn't know what to do about it. I'd tried everything I could think of but nothing seemed to help. Then I did some research and discovered the ART DTI and thought it might be answer to my prayers. After talking to a tech at Sweetwater he assured me this would be my last and best shot at solving my problem and advised me it was backed by their 30 day guarantee and if for any reason I wasn't satisfied I could return it. So with everything to gain and nothing to lose I made the purchase and boy am I glad I did. I would highly recommend the ART DTI to anyone having a problem with a hum in their setup and thanks to Sweetwater for their excellent service and products.

Initially did not remove all, but most of the noise, was pretty blown away by the difference but still had some noise at higher levels, which together with this device, and some tips on rearranging USB devices (I happened to group my USB input devices into one powered hub I also put the USB mixer on the same hub to see and have not removed it, also makes it easy to switch it all to laptop which has always been black-as-space quiet, and put it all into a different port on the motherboard of desktop PC)...

Anyway, the PC is built with gaming as a primary use, one of my pastimes. It is big, super noisy, etc. Was getting a lot of interference in the monitors. Just dreadful, had to turn the monitors way way down to make them usable. Now I can play games with my video overclocked at any level and there is no noise. Before the whining and the whirring and the mouse movements had my yamaha monitors at one notch up from minimum to get the noise low. This was with everything plugged into a basic furman; ear splitting, migraine/fatigue inducing digital noise. Now the Yamahas are in the "optimal" (the owners manual) position at center detent. I put it between USB mixer speaker output and monitors, and used it to convert final length to XLR for good measure, since the small behringer I am using does not have XLR out.

The noise from the desktop PC has been eliminated, by using this device, and refining the machines USB port arrangement as described above.

Could not be more satisfied with the result this device has helped me to achieve, and must BUMP the potential solution of rearranging/consolidating USB devices and/or using different port(s).

As for potential overall fidelity or signal degradation; any sonic signature characteristics that may be compromised, are easily outweighed by the fact that now it is *useful* rather than disgustingly tedious and/or uninspiring. End result, sounds way way better. More bluntly, before I had an incomplete, even broken experience, now it is fixed.

We use several of these in a 40-year old school cafeteria with a 'filthy' power supply -- mixing board is in back, powered monitors in front, and speakers/amps for the front of the house. These boxes, in conjunction with some isolated power boxes have significantly cleaned up the annoying 60 cycle hum that was hard to get rid of.

This is my second one. My 10 year old one still works perfectly [home studio], but I needed one for my home entertainment set up. The DTI totally eliminates ground hum.

I purchased this box to go between my computer and my speakers. I had noticed ground hum on the line and, after various troubleshooting methods, I settled on this box. The effect was very dramatic, like someone just turned off a switch. The warning, though, comes with the fact that this box solves a very specific problem. Later, I switched computers and found that this box in the loop actually *added* noise. Then I installed a Furman M8S power sequencer to the setup and the box was totally ineffective, requiring me to use a ground lift to get rid of the noise. The bottom line is that the box is worth its weight in gold to solve the problem it was designed for, but if that is not your problem, then this is not a bad product, just the wrong product for the job.

I'm not an electrician and therefore have spent hours and hours trying to figure out what was causing humming in our chapel's main and monitor speakers. The problem was exacerbated by inconsistent presence and loudness of the humming. Sometimes it's there and other times not at all. After speaking to my Sweetwater tech, Bob Furlong, he suggested using this ART DTI boxes. I inserted them inline after the signal leaves the mixer and, like a miracle, total silence!!! I literally had to put my ear within 12" of the floor monitors to hear a very faint hum. Unbelievable!!! I order three then and buying another one today. As the pictures shows, it accepts all the standard connections.

I was having some VERY strange issues with mouse movements and graphics making noise through a Focusrite USB Saffire 6 and some Yamaha studio monitors. After weeks of troubleshooting with Focusrite they suggested a product like this. I ordered this item with great skepticism. I was anxious to plug it in when it finally arrived and the clouds parted and sunshine came through! The noise is GONE! Very happy!!! WOOHOO!!!

Does the Job!!

There is still a faint hum at my desired levels, that is a different problem to resolve(?). Transformational(!) reduction in noise. Substantial(!!!) increase in usable level. Small room, PC based, USB mixer, near-field monitors, PC Gamer. No electricity/battery required.

Seeking elegant(...?) solution to problem. Have not tested just lifting the ground of the furman strip to socket because I do not want to do that, yet. Next step in seeking ideal is to add a ground-lift solution, or go whole enchilada (eventually) with something else from PC to monitors for reproduction use (like a middle high DAC with balanced outputs & ground lift). This is sufficiently resolved for most of my current "pro" usage.

My PC is close, and pretty big, and super noisy (video optimally overclocked & fan sets to 100% early). It was built with gaming as an important task.

This box has satisfied 96% of my ideal and typical use.

Does exactly what it is meant to, but is also an amazingly versatile piece of equipment. I'm using it to convert an unbalaced stereo signal; to two balanced signals for sending across an electronically noisy space, which works like a charm... because of the flexible/multiple connectors on both ends, it also allows me to interconnect other equiipment as needed. All that is missing is the ability to bolt it down easily - but that's what duck tape is for I guess.

We had a system noise issue when connecting any computer to the mixer. Now, we have eliminated probably 98% of that noise by simply inserting the ART DTI in the signal path.

i bought it because i have some hum when i use my keyboard with my audio interface. when i connected it through the ART DTI 2 the hum went down a lot but not completely eliminated.

The hum eliminator worked perfectly. I was chasing a ground loop on our live feed from the sanctuary board (via a matrix out from a Mackie onyx 24.4) to the board that feeds the radio transmitter and online feed. This worked great without affecting the levels. I'm glad and my other sound guy is as well. Thanks again

This is a good tool to have to get a jo done. Note you still have a problem in your chain. I have found xlr's that have been either poirly made or broken down over time due to not being wrapped properly. Ac wires can break down the same. Power supply's internally can hace issues. Last but not least. An outlet on a wall wired to a different breaker can introduce issues as well. As well as computer equipment and hard drives and cheap sound cards not meant for audio. If your lab is in your home and csn afford it. Pay for an electrition to come wire your room correctly. You can open your walls run the lines and lay them next to the breaker and let them finish to save u some paper.. U just have to know how to close and refinish your walls.. Just something to think about. I was on a live gig in a cafeteria every week for a church. Refrigerators all of the sudden were a problem.. So your issue can be many problem..

I bought this for our church because the keyboard had an annoying hum when plugged straight into the mixer.
This did not only NOT eliminate the hum--it actually amplified it.
I wish Samson still made DI boxes--they worked better than anything ART makes.

Not worth it. Added alot of hum/static.

It's a nicely built unit but it didn't work for me. I guess the hum is getting in from somewhere else.

Got it quickly, as usual, from Sweetwater. I have a little electrical noise with my bass and some effects, so I thought I'd give this unit a try. It actually *added* noise. Oh well.
