TDI

Featuring a proprietary circuit designed by Fred Forssel, the TDI from AEA Ribbon Mics is a phantom-powered DI box that supports perfectly transparent conversion from unbalanced Hi-Z to balanced mic-level signals. With a Thru jack for amplifiers and a -20 dB pad for handling hot signals, the TDI is an indispensable tool for the studio or stage. The TDI offers extremely low noise, interference, and distortion thanks to its JFET analog buffer and superclean Lehle stepdown transformer. A ground-lift switch is also provided for eliminating any remaining hum or noise that can arise from grounding loops. Though designed for instrument-level signals generated by passive pickups, the TDI also works great with line-level signals from drum machines, samplers, and synths. Made in the USA, the TDI is built to last with a durable steel chassis, ideal for tours, stage backlines, and years of rigorous studio use.
