Tube or solid state? It's got both!

The PreSonus BlueTube DP Stereo Preamp is among the most versatile two-channel mic and instrument preamps in its class. Its Dual Path technology lets you choose between two preamp stages: a transparent solid-state or warm tube preamp. Each gain stage of the BlueTube DP is pure Class A with high headroom.

Each channel of the BlueTube DP includes a -20dB pad, polarity reverse, 80Hz filter, and +48v phantom power. On the front panel you'll find controls for solid state gain and switchable on/off tube drive. When the tube drive is off, the tube preamplifier stage is bypassed delivering ultra-quiet and transparent solid state preamplification.

Large analog VU meters provide precise visual monitoring. Dual Neutrik combo jacks for microphones or instruments provides quality I/O and make the BlueTube DP great as a DI for electric bass and guitar.

Warm Your Signal


from Unicoi,TN

Comments about PreSonus BLUETUBE DP Stereo Dual Path Microphone/Instrument Preamp with 12AX7 Tube:

I bought this unit to warm up vocal tracks. And it has done a superb job. But, I was equally amazed at how much better it made my guitar tones on my latest recording. This unit is well worth it's weight in gold. I also used it on the kick and snare drums. Same results, Warm,Vibrant,and Lively tones. No false tone coloring,as with some cheaper units. I feel that this unit will improve any signal that is ran through it. I will be buying two more of these units, to be used on the entire drum kit.
