AEA TDI Duo Stereo Active Direct Box

As with all DI boxes, the role of the phantom-poweredTDI is to facilitate impedance matching and a drop inlevel. The TDI works by using an ultra-low-noise JFETto buffer the high impedance of your instrument-levelsignal. The JFET then drives a super-clean step-downtransformer which balances the signal. There is a THRUjack paralleled to the input jack. The TDI allows for out-standing sonic performance while minimizing distortion,noise interference, and signal degradation from longcable runs. The TDI can handle extremely high inputlevels without clipping. Its durable steel chassis canwithstand the toughest live or studio environments. ThePhantom-Powered TDI pairs great with passive instruments like guitars, basses, piezo pickups, etc. Its 20 dBpad can also flawlessly handle speaker-level signals oractive instruments such as synths as well. As with all AEAelectronics, this circuit was designed by Fred Forssell.
