ART / Solo MPA

ART/Solo MPA is a 1-channel multi-voice tube preamplifier that combines the advantages of both tubes and transistors.

1-channel multi-voice vacuum tube preamplifier

■Outline
This 1U rack-size microphone preamplifier combines the best of both worlds: vacuum tubes and transistors. It can blend the pure, low-noise/low-distortion solid-state sound with the warmth of a Class A tube. A wide and effective EQ allows you to get the sound you want.

In addition to 48 V phantom power, you can set the input impedance, so you can use a variety of microphone types, including dynamic, condenser, and ribbon. The low-cut control allows you to make vocals stand out clearly, and the tilt EQ can be used to emphasize high frequencies or warm up low frequencies.

The rugged 1U rack-size enclosure will provide years of reliable use in studios and venues.
