PreSonus BlueTube DP V2 2-channel Mic/Instrument Tube Preamp

Description

The PreSonus name is synonymous with quality and performance in any studio, and they continue to build on that reputation with the BlueTube DP v2, a 2-channel tube preamp with PreSonus' popular Class A XMAX preamps, which have been widely acclaimed for both their clarity and transparency. PreSonus tube preamps are known for their warm, smooth sound. With the Blue Tube DP dual-path mic/instrument preamp, you get both types of high-quality sound in one unit.

The BlueTube DP v2 is an improvement on the classic BlueTube DP preamp. The solid-state path now feeds PreSonus' pure Class A XMAX mic preamplifier with 80dB of variable gain-an upgrade from the original BlueTube DP's solid-state stage. The tube path features a 12AX7 tube, which operates on voltages double that of other preamplifiers in its class, producing lots of headroom and big tone. BlueTube DP v2 offers lower noise, more high-end clarity, and an even smoother tube sound than its predecessor.

You still get all the secondary features you expect in a professional-grade preamp: 48V phantom power, an 80Hz high-pass filter, -20dB pad to control hot input signals, and a polarity-reverse switch. Each channel has an illuminated VU meter so you can visually monitor your input levels.

A Tube Drive control provides a wide range of sounds: when it's clicked off, you're using the solid-state preamp for quiet, transparent amplification; when it's engaged, your signals flow through the tube preamp, and you can achieve anything from gentle warmth to edgy distortion.

Versatile and Affordable With two combo mic/instrument inputs, the half-rackspace BlueTube DP v2 is a great choice for guitars and basses as well as for vocals. Singer-songwriters can run their vocal through one channel and their guitar through the other, feeding both to the P.A.-no guitar amp needed. It also serves as a DI box, thanks to balanced XLR and unbalanced 1/4" outputs, and is housed in a new, rugged, 1/2U case. Try the BlueTube DP v2 as a front end for a DAW, too; sure, your recording interface might already include preamps, but few of them give you both tube and solid-state operation.

We have also updated the preamp's compact, rugged enclosure; it has more rounded edges and looks modern and sleek. It can be used as a desktop unit or it can be screw-mounted to a standard rack tray.
