ART DTI Dual Transformer/Isolator

The ART DTI (Dual Transformer/Isolator) is a high quality 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 when used 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 k ohms.

What further sets the DTI apart from other lesser isolation boxes is its connection versatility. ART has provided XLR, 1/4" phone, and RCA type phono connections on all inputs and outputs. This allows it to easily fit into virtually any audio system and be the clean patch point between all types of systems.

Whether you need an interface between a computer based audio workstation and your monitor system, isolation on long cable runs in a fixed installation, isolation of a signal source from your recording equipment, or in many cases, just a safer connection between two audio systems, the DTI can accommodate.

The compact black anodized all aluminum case and its passive design allow the DTI to provide years of trouble free service in Live Sound, Permanent/Fixed Install, D.J., and virtually any PA application. Its full feature set, rugged construction, and high-end specifications make the DTI the obvious choice.

Specifications: • Frequency response: 10Hz to 50 kHz • THD: 0.01% Typical @ 1kHz • Insertion loss: 0.4 dB @ 100 k ohm load, 5.5 dB @ 600 ohm load • 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 • Power requirements: None, passive • Dimensions: 1.75" x 4.2" x 3.5" • Weight: 0.75 lb.

ART DTI Dual Transformer/Isolator
ART DTI Dual Transformer/Isolator is rated 4.5 out of 5 by 6.
Rated 5 out of 5 by from A Great little boxThe front speakers of my Hi-End A/V system had a terrible hum that you could hear at low levels. After installing it between the pro-EQ and separate Amp that powered the front speakers the hum was eliminated. The ART DTI is an amazing product and perhaps the greatest price/value item in my system that includes a Marantz AV-7005 pre-amp processor and a pair of Magnepan 1.6Q/R (flatpanel) speakers.

Rated 4 out of 5 by from It worksBought this to connect a TV audio out to my sound system. Have had a lot of hum problems directly connecting the TV audio because of cable ground loop issues. Using this little box cured the ground loop hum, and now I can use my full high end audio system to listen to the TV. Not sure of the actual frequency response though, the bass sounds a bit thin for a claimed 10 Hz lower 3 dB point.

Rated 4 out of 5 by from Good interconnection box, solves problemsA useful problem solving box. I have used this to connect laptops to PA systems, to connect a line level signal from a stereo system to a USB recording device, and to connect a cheap consumer karaoke machine to a pro PA. In all cases there was a buzz in the background that dissappeared when I used the transformer isolator.The transformers are quite small, this is not a very high quality unit in audio terms, but for the price it's fine. Each time I have used this box it has made an unacceptable situation (buzz/noise bad enough for complaints from customers) into a 100% good result. I have some top end Radial and Whirlwind direct boxes in my arsenal too at 4x the price, they all have their place in different situations.

Rated 4 out of 5 by from Excellent product!I wish I thought of it first. It's just too convenient having the ability to connect two systems together in stereo and without the need for different adapters as well. Awesome!

Rated 5 out of 5 by from Great product.I am very impressed with this isolator. After a suitable break-in period, the unit is quite transparent. It resolved a host of noise issues when connecting my laptop to a pair of high-end powered loudspeakers.Between this unit and a couple of new cables I bought, it took several days of continuous use to break in. (The speakers were well used by this point.) Initially, the sound was a touch muffled, but all that resolved itself after the system was used for around three days.

Rated 5 out of 5 by from No muss, No fussWorks to remove ground hum when the components connected by the audio cables are not plugged into the same place. Just plug it in. No power needed
