DTI Dual Transformer / Isolator Hum Eliminator Dual Wireless Mic Systems the D112 MkII features anThe DTI (Dual Transformer Isolater) 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 DTIs audio transformers have an extremely flat and wide frequency response and can handle high signal levels while an isolated balanced output. This gives the DTI a very clean and neutral
