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

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.
