About PreSonus TubePre V2

Explore the world of superior audio quality with the TubePre V2 Mono Tube Preamp (1/3U) from Presonus, a brand synonymous with professional and high-quality audio equipment. This innovative tube preamplifier is the upgraded version of the popular TubePre, designed with an unwavering focus on enhancing the already impressive sound quality.

The TubePre V2 stands out in its class, thanks to its fully professional tube preamp and a dual-servo gain stage. This unique design allows you to amplify the program signal to extreme levels without a significant increase in background noise. The use of discrete components and high-voltage operation ensures an unmatched dynamic range and detail, setting this tube preamp apart from its competitors.

Experience a broader spectrum of sound options with the TubePre V2. It boasts a more concentrated tube saturation than its predecessor, achieved through the integration of Presonus' renowned XMAX Class A solid-state preamp. This is followed in the signal path by a 12Ax7 vacuum-tube stage. The TubePre V2 Drive saturation control allows you to add the distinct color that only a hand-selected 12Ax7 vacuum tube can provide, ranging from gentle warmth to intense fuzz.

The TubePre V2 is not just versatile but also feature-rich. Encased in a durable and rugged case, its rear panel features separate unbalanced, 1/4" instrument and balanced, XLR mic inputs, along with unbalanced 1/4" and balanced XLR line outputs. It comes equipped with professional-grade extras such as a high-pass filter, phantom power for condenser mics, a polarity reverse switch, and a backlit VU meter.

But the TubePre V2 is more than just a mic preamp. With its separate instrument and mic inputs, it doubles as a powerful direct box (DI) for guitars and basses. Its compact size makes it portable and easy to carry, yet it can also be securely mounted to a standard rack tray.

Whether you're a fan of the original TubePre or discovering the TubePre V2 for the first time, prepare to be amazed by the rich, warm sound this reliable and innovative tube preamp can deliver. With Presonus, you can enjoy big, professional sound without the big price tag.
