PreSonus BlueTube DP v2 is a 2-channel microphone preamp, and 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. The BlueTube DP v2 provides lower noise, more high-end clarity, and an even smoother tube sound than its predecessor.

All the secondary features you expect in a professional-grade preamp include 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.

The BlueTube DP v2 features a Tube Drive control that offers 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.

PLEASE NOTE: the “DP” in BlueTube DP v2 stands for Dual Path.


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.
