ไมโครโฟนพรีแอมป์ Single Channel แบบ Tube จาก Presonus รุ่น TubePre V2 ช่วยเพิ่มความอุ่น และหนาของเสียง

The PreSonus TubePre V2 compact microphone preamplifier gives you serious value for your money. Affordable portable and packed with a wide range of rich tube tone TubePre V2 is one piece of gear youll constantly find new uses for. First theres the TubePre V2s XMAX Class A preamp an astonishingly clean pre that plays well virtually any microphone you can get your hands on. Then theres a the tube tone circuit which lets you dial in the perfect amount of color. And thats just part of what makes the PreSonus TubePre V2 one of Sweetwaters favorite affordable preamps.

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.
