Among the world's most popular external microphone tube preamps, the Tube MP from ART delivers fat warmth and a massive 70 dB of gain through its hand-selected 12AX7a vacuum tube. Ideal for microphones, instruments, and line-level sources, this portable, all-steel preamp delivers the real sound of a pro studio to the masses, providing superior sonic performance to onboard preamps on low-cost mixers and interfaces while maintaining very low noise.

Variable input and output gain controls let you precisely adjust your signal levels, and the handy onboard phase reversal switch and +48V phantom power selection are great utilities for achieving an optimal sound with any microphone or audio source. With an impedance matching input, the Tube MP functions as an excellent DI box as well, and the use of both XLR and 1/4" I/O lets you connect to and from any range of audio equipment. The Tube MP includes a universal switching power supply for global compatibility.
