Presonus Firestudio Tube ! - With the addition of the FireStudio Tube audio interface, PreSonus expands their successful FireStudio line.

The FireStudio Tube brings the best of the past (the tube preamp on two channels) and blends it with modern technology (low jitter clock and FireWire) to create an audio interface with a variety of sonic colors. FireStudio Tube is a perfect fit in any studio. GotoPresonus Firestudio Tube !
