PreSonus has been designing preamps for a long time, and focuses on audio quality first. The recent upgrade of the popular TubePre V2 focuses on improving an already high-quality sound-without increasing 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, 1/4" instrument and balanced, XLR mic inputs and unbalanced 1/4" 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. Additional Features: - 80 Hz high-pass filter
