PreSonus BlueTube DP v2 is a 2-channel microphone preamplifier that improves on the classic BlueTube DP. In addition, the solid-state path feeds PreSonus’ pure Class A XMAX mic preamp with 80dB of variable gain, which is an upgrade from the original BlueTube DP’s solid-state stage. The tube path features a 12AX7 tube that operates at a voltage double that of other preamplifiers in its class, providing good headroom and big tone. The BlueTube DP v2 offers higher high-end clarity, a smoother tube sound, and lower noise than its predecessor.

A professional-grade preamp features 48V phantom power, an 80Hz high-pass filter, a -20dB pad for controlling hot input signals, and a polarity reverse switch. You can visually monitor your input levels by using the illuminated VU meter on each channel.

The PreSonus BlueTube DP v2 includes a Tube Drive control that offers a variety 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. Gigasonic will ship your BlueTube quickly and provide excellent customer service.

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.
