ART DTI

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 balanced, and RCA type phono jacks, Output Connection: XLR male balanced, 1/4" TRS balanced, and RCA type phono jacks, Dimensions 44.5mm x 107mm x 89mm, Weight 0,34 kg

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"

Good DI

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.

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...

Nice and finally quite.

I finally got reed of background noise. If you know of what I'm talking about I have no need to go further than that. If you have no idea of what I mean please turn on your PC sound system gear and listen if the speaker has any hum or background noise. If so you need one of these baby :o)

Thomann customer service suggested this to me and again they nailed it down :o)

I never thought this would work!

I have been suffering a high pitched whistle on my KRK monitors, since I bought them last month, I tried everything, new cables etc.
Using balanced cables did reduce the noise by 25% but still annoying!
Then a good friend told me about this box!

I have just connected it between my Interface (Mbox) and the monitors, and hey presto, SILENCE! the noise has gone completely.
I am very happy, best 30 quid I have spent in a while!

The unit is small & robust.

I really didn't believe it was gonna work!
