AEA TDI Active DI Box

The AEA TDI works by using an ultra-low-noise JFET to buffer the high impedance of your instrument-level signal. The JFET then drives a super-clean step-down transformer which balances the signal. There is a THRU jack paralleled to the input jack. The TDI allows for out- standing sonic performance while minimizing distortion, noise interference, and signal degradation from long cable runs. The TOI can handle extremely high input levels without clipping. Its durable steel chassis can withstand the toughest live or studio environments. The Phantom-Powered TDI pairs great with passive instruments like guitars, basses, piezo pickups, etc. Its 20dB pad can also flawlessly handle speaker level signals or active instruments such as synths. As with all AEA electronics, this circuit was designed by Fred Forssell.
