With a proprietary circuit design by Fred Forssell and a superclean Lehle step-down transformer, the ultra-transparent TDI Duo captures outstanding sonic performances with minimal distortion, noise interference or signal loss from long cable runs.
 
The Duo's active circuitry delivers top-grade sound quality while minimizing distortion and noise interference and maximizing your signal over long cable runs. A ground-lift switch eliminates any remaining hum or noise that can arise from grounding loops.
 
Though designed for instrument-level signals generated by passive pickups, the TDI Duo is also perfect for line-level signals from drum machines, samplers, and synths.
 
The TDI Duo is built to last with a rugged steel chassis, ideal for tours, stage backlines, and years of rigorous studio use. You can also mount three TDI Duos onto a standard 19-inch universal rack tray to create a six-channel 1U DI station.
