Vacuum Tube and Solid-State Performance in One Amazing Preamp

BlueTube DP V2: 2-channel, dual-path mic/instrument preamp

A dual-personality preamp with an amazing variety of tones.

Compact, affordable, and capable of a stunningly wide range of tones, the BlueTube DP V2 dual-path mic/instrument preamplifier offers two independent channels, each with an XMAX Class A solid-state preamp, followed in the signal path by a 12AX7 vacuum-tube stage. A Tube Drive control provides a wide range of sounds: When clicked off, you’re using the solid-state preamp for quiet, transparent amplification; when engaged, your signals flow through the tube preamp, and you can achieve anything from gentle warmth to edgy distortion. Equipped with instrument and mic inputs and built tough for serious gigging, the BlueTube DP V2 is a great choice for guitarists, bassists, singer/songwriters, and more.

Transparent solid-state, warm tube distortion, and everything in between.

With the BlueTube DP V2 dual-path preamp, you get the best of two worlds. Our popular Class A XMAX solid-state preamps are widely lauded for their clarity and transparency, delivering incredibly high headroom, deep lows, smooth highs, and a rich overall sound. Found in many PreSonus products, it has received nothing but raves from users and the media alike. Our tube preamps are beloved for their warm, smooth sound, and the 12AX7 vacuum tubes in the BlueTube DP V2 are hand-selected and carefully tested to ensure top audio performance. Whether you want clean, transparent sound; ear-shredding fuzz; or something in between, you can achieve it with the BlueTube DP V2.

The job of a microphone preamplifier is to boost a microphone-level signal to line level before conversion to the digital domain. A good preamp boosts the level to almost 400 times that of the original signal, making the preamp one of the most important stages in an interface. A cheap, off-the-shelf, op-amp-type mic preamp delivers thin, noisy, harsh results. But with XMAX preamps, the sonic quality is limited only by the microphone you plug into it.

XMAX preamplifiers are built with three key elements:

  • Class A. Class A circuits have no crossover distortion and deliver purer, clearer, and more musical results than the Class AB designs that are found in many preamps.
  • High Voltage. The XMAX preamplifier runs on power rails of 30V. Most off-the-shelf, op-amp-based designs run on power rails of 10V to 18V. Higher-voltage power rails deliver more headroom, deeper lows, smoother highs, and a richer overall sound.
  • Discrete components—not op-amps. We only use genuine transistors, resistors, and capacitors. Op-amps add noise, coloration, and harshness to a signal. Our discrete design delivers ultra-low noise and transparency.

The net result of the XMAX preamp design is high headroom, low noise, wide dynamic range, extended frequency response, and—most important—musicality and transparency.

The most versatile preamp in its class—and built to travel.

The BlueTube DP V2 offers far and away the widest variety of tone-shaping capabilities of any preamp in its class. Housed in a rugged, half-rackspace case that is built to travel, its rear panel sports two combo mic/instrument inputs and unbalanced ¼” and balanced XLR line outputs. With two dual-path channels and this complement of I/O, you can use it as a preamp and as a direct box (DI) for guitars and basses. 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. And we didn’t forget the extras: an 80 Hz highpass filter, phantom power, a -20 dB pad to control hot input signals, polarity reverse, and a backlit VU meter. Yet the BlueTube DP V2 is small enough to carry in a gig bag—or screw-mount it to a standard rack tray.

Two channels of great sound, live or in the studio.

Live or in the studio, the BlueTube DP V2 is a great-sounding tool you’ll use on a variety of sources. Add just the right amount of tube distortion to guitars, basses, and mic signals. Go lightly for gentle warmth or go all-out for solid crunch. Use one channel as a solid-state preamp and the other as a tube preamp—it’s up to you.
