PreSonus TubePre V2 

Mono Tube Preamp

Improving on a Great Sound
 
At PreSonus we’ve been designing preamps for a long time and we always focus on audio quality first. So when we decided to upgrade our popular TubePre V2 we focused on improving an already high-quality sound—without jacking up the price. Like the original TubePre the new version is a fully professional tube preamp with a dual-servo (no capacitors) gain stage that lets you boost the program signal to smoking hot levels 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.

Versatile and Feature-Rich

Housed in a rugged case the TubePre V2 rear panel sports separate unbalanced ¼” instrument and balanced XLR mic inputs and unbalanced ¼” and balanced XLR line outputs. We’ve 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 though.
 
Thanks to its separate instrument and mic inputs it also serves as a dynamite direct box (DI) for guitars and basses. And it’s small enough to carry almost anywhere although you also can screw-mount it to a standard rack tray.
 
So if you are a fan of our original TubePre you’re going to love the improved TubePre V2. And if you are checking out the TubePre for the first time your ears are in for a real treat. Then check out the amazing low price—but sit down first because you’re in for a shock. Because with PreSonus big sound does not have to cost big bucks.
