Like PreSonus' original TubePre, the v2 is a fully professional tube preamp, with a dual-servo (no capacitors) gain stage that lets you boost the program signal without significantly increasing the background noise.  Discrete components and high-voltage operation offer dynamic range and detail not found in other single-channel tube preamps in its class.

But the TubePre V2 provides an even wider palette of sound options, and a much more focused tube saturation, than the original TubePre.  It has been upgraded to employ PreSonus' popular XMAX Class A solid-state preamp, which is followed in the signal path by a 12AX7 vacuum-tube stage.  Twist the TubePre V2 Drive saturation control to add the "color" that only a hand-selected 12AX7 vacuum tube can deliver — from gentle warmth to total fuzz.

Housed in a rugged case, the TubePre V2 rear panel sports separate unbalanced, 1/4" instrument and balanced, XLR mic inputs and unbalanced 1/4" and balanced XLR line outputs.  PreSonus has included all of the extras you need for professional operation including a high-pass filter, phantom power for condenser mics, polarity reverse switch and a backlit VU meter.

The TubePre V2 is more than a mic preamp.  Thanks to its separate instrument and mic inputs, it also serves as a direct box (DI) for guitars and basses.  And it's small enough to carry almost anywhere, although it can also be screw-mounted it to a standard rack tray.
