AEA TDI DUO Dual Phantom-Powered Stereo Direct Box

AEA TDI DUO Dual Phantom-Powered Direct Box

As with all DI boxes, the role of the phantom-powered AEA TDI is to facilitate impedance matching and a drop in level. The 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 outstanding sonic performance while minimizing distortion, noise interference, and signal degradation from long cable runs. The TDI 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 20 dB pad can also flawlessly handle speaker-level signals or active instruments such as synths as well. As with all AEA electronics, this circuit was designed by Fred Forssell.

Application

TThe straight-forward design of the TDI makes set-up and usage simple. Power for the TDI is supplied with standard 48V to the XLR output. Simply plug the 1/4″ cable from your instrument into the INPUT jack of the TDI, and connect the OUTPUT via XLR to the next device in your signal chain (preamp, PA, audio interface, etc.), then engage phantom power. Optionally, you can also use the THRU-put to send your instrument signal to other instrument-level sources (such as amplifiers). The THRU-put feature is also useful for simultaneous wet/dry signal tracking.
