TDI Duo
DI Box
From AEA:
With a proprietary circuit design by Fred Forssell and a superclean Lehle step-down transformer, the ultra-transparent TDI and TDI Duo capture outstanding sonic performances with minimal distortion, noise interference or signal loss from long cable runs.
Inspired by our straightforward design philosophy and our desire to offer outboard DI alternatives, we created the AEA TDI and TDI Duo.
The TDI and TDI 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.
