PreSonus Bluetube DP V2

The Presonus BlueTube DP V2 is a highly versatile stand-alone mic preamp fit for the studio or on the road and offers two channels that are selectively solid state or tube. This input stage is based on the companies Class-A XMAX preamp circuit, and the user has the ability to dial in the desired amount of valve warmth from the 12AX7 vacuum tubes, or to use the solid state circuitry only. This gives the option of a completely transparent experience, or one that is coloured with tone and saturation.

The face of the preamp displays all the usual features: a switchable 48V phantom power switch, a 80Hz high-pass filter, a -20dB pad, and a polarity switch. It has Illuminated VU meters and LED lights for checking input levels.

PreSonus’s popular Class A XMAX solid-state preamps are widely lauded for their clarity and transparency, delivering incredibly high headroom, and very low distortion and low noise with a flat frequency response. Switch the Tube Drive on and turn it up to discover a much more solid, thick response without such an increase in overall output. This flatters vocals and guitars, and gives a noticeably saturated quality that is widely usable, not offending any of the higher frequencies as some may expect.
