Overview

The ART DTI is a passive, stereo dual transformer isolator designed to eliminate hum and ground loop noise, providing a clean, neutral signal path. It converts unbalanced or balanced input from XLR, TRS, or RCA sources to fully isolated balanced outputs—making it ideal for connecting mixers, instruments, or playback devices to PA systems or recording interfaces. Its compact, anodized aluminum housing is road‑worthy and dependable for live sound, studio, installation, or playback applications.
