Thank you for choosing the AEA TDI phantom-powered
direct box. Your Active TDI is an indispensable tool for
both live and studio use, and we hope this box helps
you in capturing many wonderful sonic experiences.
TDI Overview
As with all DI boxes, the role of the phantom-powered
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 out-
standing 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 instru-
ments (guitars, basses, piezo pickups, etc.), but, with its
20 dB pad, can 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
The 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 an amplifiers). The through-put feature is also useful
for simultaneous wet/dry signal tracking.
