一个具有令人印象深刻的动态范围和细节的前置放大器。

设计紧凑且负担得起，一直流行的 TubePre V2 专业电子管前置放大器采用我们广受赞誉的 XMAX  A 级固态前置放大器，在信号路径后跟着一个 12AX7 真空管阶段。双伺服(无电容器)增益阶段，即便是提高信号到冒烟的热水平也不会有明显增加的噪音。离散元件和高压操作提供了动态范围和细节，这在同类的单通道管前置放大器中是没有的。TubePre V2 质地坚固，是吉他和话筒类产品的绝佳选择。

From gentle warmth to total fuzz with the twist of a knob.

XMAX microphone preamps deliver incredibly high headroom, deep lows, smooth highs, and a rich overall sound garnering them rave reviews from users and the media alike. The 12AX7 vacuum tube that follows the XMAX in the TubePre V2 was hand-selected and carefully tested for electrical conformity and freedom from microphonics. Twist the Drive saturation control to add the “color” that only a hand-selected 12AX7 can deliver — from gentle warmth to total fuzz.

A versatile tool that's built to travel.

Housed in a rugged case that is built to travel, the TubePre V2 rear panel sports separate unbalanced, ¼” instrument and balanced, XLR mic inputs and unbalanced ¼” and balanced XLR line outputs. Use it as a straight-up tube preamp or a dynamite direct box (DI) for guitars and basses. We’ve provided all of the extras you need, including a highpass filter, phantom power, polarity reverse, and a backlit VU meter. Yet with all its features, it’s small enough to carry almost anywhere—or simply screw-mount it to a standard rack tray.

Great sound, live or in the studio.

Live or in the studio, the TubePre V2 is a great-sounding tool you’ll use on a variety of sources. Add just the right amount of tube distortion to guitars, basses, and mic signals. Go lightly for gentle warmth or go all-out for solid crunch—it’s up to you. So give your ears a treat and test the TubePreV2 at your favorite PreSonus® dealer. Then check out the price— and prepare to be amazed. Because with PreSonus, big sound does not have to cost big money.
