ART / Solo MPA

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

■ 1-Channel Multi-Voice Vacuum Tube Preamplifier

■ Overview

This unit is a 1U rack-sized microphone preamplifier that combines the advantages of both vacuum tubes and transistors. It blends the pure, low-noise/low-distortion sound of solid-state with the warm sound of Class A vacuum tubes. The wide-ranging and highly effective EQ allows you to achieve your desired sound.

With 48V phantom power and adjustable input impedance, it can be used with various types of microphones, including dynamic, condenser, and ribbon microphones. The low-cut control allows you to clearly accentuate vocals, while the tilt EQ can be used to emphasize high frequencies or enhance the warmth of the low frequencies.

It's also ideal for those who want to further upgrade the microphone preamplifier built into their equipment. The robust 1U rack-sized enclosure ensures reliable use in studios and venues for many years to come.
