ART DTI Dual Input Inline Transformer/Isolator Box w/Balanced and Unbalanced ConnectorsThe DTI (Dual Transformer Isolater) from ART 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 unit'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
