DTI
Dual Transformer / Isolator

"I was so impressed that the DTI is now permanently in my problem-solving kit box. Highly recommended." - Sound on Sound (Link)

The DTI Dual Transformer / Isolator uses a pair of high-performance transformers to reduce hum and ground loop noise, separating the input and output signal grounds for total isolation between two systems.

The transformers are wound for 1:1 unity gain, and have an extremely flat and wide frequency response. Even at high signal levels, they provide clean, transparent sound.

With XLR, 1/4” TRS, and RCA connectors on all inputs and outputs, the DTI is flexible and easy to integrate. Featuring a rugged aluminum enclosure and a passive design that doesn’t require external power, the DTI is built for years of reliable use.
