Get to know them!

ART’s Solo MPA multi-voice tube preamplifier is a beginner-friendly entry into the world of outboard preamplification. The 1-channel preamp injects your signal with warm tube tone shaped by intuitive controls and features. You get XLR microphone inputs on the back panel with phantom power for condenser mics and a front-mounted high-impedance input for instruments. Operation is simple. First, dial up the ideal microphone sound using the adjustable input impedance knob. From there, use the tilt EQ and low-cut filter to shape the sound to perfection. Sweetwater recording engineers note that the Solo MPA keeps total harmonic distortion (THD) to an absolute minimum, ensuring noise-free recording for all occasions. Go with the ART Solo MPA multi-voice tube preamp and take your sound to the next level.

Everyone should have a good mic pre

External preamps are a great way to add more spice to a signal while recording. The ART Solo MPA preamp’s selectable input impedance and tilt EQ deliver sonic coloration in spades. The adjustable impedance lets you dial in a wide range of microphone voicings. Meanwhile, the tilt EQ shapes the bass and treble simultaneously. If you boost the bass, the treble is reduced proportionally and vice versa. There’s also a low-cut filter to tame any unruly bass frequencies. By using the Solo MPA, you can improve the sound of any signal and augment your productions.

Flexible tube-fueled tone

The Solo MPA preamplifier leverages old-school vacuum tubes to inject your signal with warm tube tone. You get flexible controls to dial in the perfect sound for any source. First, the tilt EQ offers easy tone-shaping. Meanwhile, the adjustable input impedance helps you get more sounds from your microphone. Whether you’re plugging in a microphone or an instrument, the Solo MPA multi-voice tube preamplifier makes any signal sound its best.

ART Solo MPA Multi-voice Tube Preamplifier Features:

  • Injects your microphone signal with warm tube goodness
  • Front-mounted hi-Z instrument input
  • Adjustable input impedance enables flexible microphone voicings
