ART DTI Dual Transformer / Isolator
Featuring a multitude of possible input/output types, this two channel passive interface is used to eliminate hum caused by the presence of ground loops. 3 types of inputs and outputs make it incredibly versatile and it's high capacity transformers leave the signal true to source.

Ground Loops
Vast expanses of electrical wiring interconnected through equally vast expanses of audio equipment will invariably cause what is known as "hum". This is a 60hZ drone caused most commonly by a "ground loop", that is a link between one power outlet socket's grounding connection and another's, via connected audio equipment.

Eliminates ground loop noise without affecting signal
The DTI is a high-quality totally passive audio interface that uses two 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 100k Ohms.

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

Sturdy all-aluminium case requires no power
The DTI's compact black anodised all-aluminium case will stand up to the rigours of road use. Thanks to its passive design, you don't need to worry about power connections. This box will provide years of trouble free service!

Works great in any studio, live sound or fixed installation
Whether you need an interface between a computer-based audio workstation and your monitors, 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. In live sound, permanent/fixed installations, DJ booths and virtually any PA application, the DTI's full feature set, rugged construction, and high-end specifications make it an audio essential!

This is a magic box

I had a small 50hz hum from earth leakage with my powered speakers. It took 2 min to install and like magic the hum was gone. Speakers still have heaps of headroom and full frequency response. I am a very happy camper!!
