About PreSonus

The PreSonus BLUETUBE DP is a two channel microphone/instrument preamplifier with Dual Path technology that delivers the best of both worlds. It offers a solid state preamplifier stage and a tube preamplifier stage in each channel, delivering either fat, warm tube tone or invisible solid state transparency.

Each channel of the BLUETUBE DP includes a -20dB pad, polarity reverse, 80Hz filter, and +48v phantom power. Front panel controls include a solid state GAIN control and switchable on/off Tube Drive. When the Tube Drive is clicked off, the tube preamplifier stage is bypassed delivering ultra-quiet and transparent preamplification. The front panel also includes illuminated analog VU meters for each channel for easy visual monitoring.

The BLUETUBE DP is great for enhancing all types of microphones including condensers, dynamics and ribbons, as well as instruments including keyboards, acoustic and electric guitars and bass. The unit is the perfect front-end preamplifier for any project studio, delivering a wide range of sounds and tonality.
