The Presonus BLUETUBE DP 2-channel microphone and instrument preamplifier / preamp with "Dual Path" technology offers you the best of 2 worlds: a transistor preamp & a tube preamp in each channel! This new "Dual Path" (2-way) feature makes the Presonus Bluetube DP probably the most flexible preamp in its price range. On the one hand, the fat, warm tube sound or the clear, transparent transistor sound. The new BLUETUBE DP two channel microphone/instrument preamplifier with Dual Path technology delivers the best of both worlds offering a solid state preamplifier stage and a tube preamplifier stage in each channel. This new Dual Path feature delivers the most flexible preamplifier in its price range by delivering both fat warm tube tone or invisible solid state transparency. The BLUETUBE DP replaces the original award-winning BLUETUBE as PreSonus' most affordable two-channel microphone/instrument preamplifier. Each channel of the BLUETUBE DP includes a -20dB pad, polarity reverse, 80Hz filter, and +48v phantom power. Front panel controls include 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's inputs are professional-quality Neutrik Combo connectors for inputting both XLR and 1/4" TS sources. Outputs include both XLR and TS jacks allowing for ultimate flexibility. The PreSonus BLUETUBE Dual Path is great for enhancing all types of microphones including condensors , dynamics and ribbons, as well as instruments including keyboards, acoustic and electric guitars and bass. The BLUETUBE DP is the perfect front-end preamplifier for any project studio delivering a wide range of sounds and tonality all at an amazingly affordable price.
