ART Solo MPA Single-Channel Tube Microphone Preamplifier

Clean solid-state or colorful tube sound? Blend them both with ART's multi-voice Solo MPA, an affordable preamp channel with variable impedance and tilt EQ.

The ART Solo MPA MultiVoice Tube Preamplifier picks up where built-in preamps drop off. Combining the best of both worlds, the single-channel rackmount Solo MPA allows users to blend between a pristine low-noise/low-distortion solid state transistor circuit and a warmer Class-A tube mic preamp. Along with the flexible EQ controls, users can voice the Solo MPA to create their own signature sound.
