ART DTI

I have two of these and will probably end up with more! Hum loops can be a pain when setting up a PA rig in "unknown territory" and it wouldnt be the first time that earth wires have been temporarily removed from mains plugs etc, which whilst solving one problem creates another with regards to potential safety. These little beaties put all that behind us. With just about every possibly combination of in and out through phono, jack and xlr you can isolate 95% of all known audio connections. It is also possible with a little cunning to use it as a balanced signal generator/splitter, by using a short phono to phono link on the input side a single xlr or jack input can be fed to both internal transformers producing two separate, balanced outputs. A trick I have used a few times now.

Sturdy and well built a couople of these should be in every sound techs "goody bag"

I've used this DI to connect from my digital piano to a mixer and to a monitor speaker. Two channel inputs and outputs: two mono jack outputs from the piano to the XLR inputs of the DI, and XLR outputs to the mixer and the monitor. Removed nasty humming and buzzing to the 'minimum' (didn't quite completely eliminated the unwanted sound). But I can only hear it when I stick my ear right next to the speakers. The only issue I found was since the male XLR cables do not click or lock on the input female channels, they seemed to slip off sometimes which made me to check regularly if they are plugged in properly. But overall happy about the item and the price.

We got an old mixer for free. A large beast, but it was free. It turned out that if you hook a microphone directly to it, you can feel a small, electric jolt on your lips. Not good, it can even be dangerous. Enter the ART DTI. With this baby the jolts went away, and it can even to a small extent solve hum problems caused by ground loops too. I simply love this little thing, and having two separate channels means you can have two microphones instead of one connected or use it for stereo. It is also an adapter, by the way. It now is in permanent use in our rehearsal room. Maybe I'll get one more...

Absolutely a wonderful device !!!
It was just what I was looking for in my Home studio.
Got rid of all that terrible, static, high pitched noise that was coming out of my Studio Monitors.
It is a really impressive noise killer.
I can Highly recommend this for live use as well as home use.
If you're sick of of ground loops, this is the thing you need !
Now I can work in a complete silence.
I am very impressed with the high quality and not so expensive solution.

Also (Thomann quick delivery always surprises me) :-)

All the Best.
