Tech21 SansAmp XDI Direct Recording Interface

Bridging the Gap from Guitar to Computer.
Tech 21 has yet again redefined the term "direct box" with the development of SansAmp XDI, an instrument interface for SansAmp direct recording software (a SansAmp PSA-1 Plug-In* for Pro Tools co-developed by Tech 21 and California software company Bomb Factory), mixing consoles, and computer sound cards.

SansAmp XDI's unique design features advanced, low noise F.E.T. technology to provide a natural, transparent guitar signal to your computer. There are 2 outputs: a balanced XLR and a Lo Z 1/4 in., which eliminates the need for an XLR converter for sound cards that accept an unbalanced input; and there are two 1/4 in. inputs: Normal and Bright. Faithful to the original design of traditional tube amplifiers, these 1/4 in. inputs are high impedance 1M Ohm. The Bright input simulates the EQ curve found in traditional tube amplifiers with bright inputs. For general purposes, it can also function as a standard transparent active direct box to preserve signal integrity when transmitting a signal over long cable lengths.
