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