The BlueTube DP v2 provides the preamp you need, from perfectly clean to pleasantly distorted, and everything in between. Don’t settle for a one-trick pony mic pre; instead, acquire the PreSonus BlueTube DP v2 2-channel preamplifier today!

Class A XMAX microphone preamps provide incredibly clean sound and plenty of boost.
The same PreSonus XMAX preamplifiers that come with your BlueTube DP v2 are used in live sound rigs and recording facilities all around the world. Why? Because these very inexpensive Class A preamps give an extraordinarily clean signal path all the way up to their 80dB maximum. That’s a lot of gain and headroom! Add a 20dB pad and phantom power to both BlueTube DP v2 channels, and you’ll have a pair of great-sounding preamplifiers that can be used with any microphone.

Dual 12AX7 tube gain circuits allow you to get rich tube saturation.
Clean sound is fantastic for some things, but if you want to warm up your vocals or liven up your condenser mics, you’ll like the BlueTube DP v2’s tube drive circuits. The BlueTube DP v2’s multiple signal routes allow you to customize your tone, which is one of its distinguishing features. That’s because when you add the tube circuit, you’re not just increasing the gain; you’re also blending the clean XMAX preamp with the harmonically rich tube preamp signal. This allows you to adjust your tone from perfectly pure to full tube saturation.

This preamp is not only wonderful for mics; it’s also a superb tone box for your guitar or bass.
With such a wide range of tones, it would be a shame to limit your BlueTube DP v2 to microphone use. That’s why PreSonus designed a separate instrument input directly inside each channel’s XLR combo jack. Plug in your guitar or bass, and your BlueTube DP v2 instantly transforms into an impedance-matched direct box. Crank up the tube tone and you’ll have amazing guitar breakup or rich fuzz bass – no amplifier required! In fact, if you’re performing solo, your BlueTube DP v2 preamplifier may suffice as your PA system.
