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. ? Read More About XMAX Preamps
