ART DTI Dual Transformer/Isolator - a high quality, totally passive audio interface that uses a pair of high performance transformers to totally separate input and output signal grounds, thereby isolating two systems and reducing hum and ground-loop noise. The DTI's audio transformers have an extremely flat and wide frequency response and can handle high signal levels while maintaining an isolated balanced output. This gives the DTI a very clean and neutral sound with a wide variety of signal sources. The transformers are wound for 1:1 unity gain and are designed to be used with impedances from 600 Ohms to 100 kOhms, Input Connections: XLR female balanced, 1/4" TRS, unbalanced, and RCA type phono jacks, Output Connection: XLR male balanced, 1/4" TRS, unbalanced, and RCA type phono jacks, Dimensions 44.5mm x 107mm x 89mm, Weight 0,34 kg

A small handy general purpose DI. It will not replace my Radial products, but at this price, I don't expect it to.

Handy for throwing into your gig bag, in case you get the dreaded ground loop hum. Also works on laptops.

Great product at a brilliant price.

This very solid bit of kit is as rugged as they come.

I bought this because I was having ground loop hums from my laptop while DJing, however I have to say the one downside of this unit is that it doesnt really come with accurate instructions for an idiot like me to use. I understand you can plug in one type of connector one side and take out another type on the other but as for reducing ground loop hums I never quite knew what to do. However, as I had stopped having the problem I never needed to.

So if you are looking for a very high quality transformer from one cable to another, this is the one to go for.

Nothing fancy. Does what it says on the box. Durable. Value for money

Great solution for the problems it is made to solve

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...
