The ART DTI (Dual Transformer/Isolator) is 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 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.
What further sets the DTI apart from other lesser isolation boxes is its connection versatility. We have 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.
