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..

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.
