Digital Interfaces / Mixers



The ART Tube Mix provides a compact versatile audio interface. The Mixer supports two mic inputs, one high Impedance Instrument input, and two line inputs simultaneously. The Tube can be assigned to act as a dual channel tube mic preamp, or stacked and applied to the Instrument input for added warmth and tone with guitar or bass.
