Independent shopping perspective
MOTU’s M4 is a 4-in/4-out USB-C interface for recording and monitoring on Mac, Windows, or iOS. Two XLR combo inputs cover mic, line, and hi-Z instrument sources, while two additional balanced line inputs expand the input side. The color LCD keeps input and output levels visible during recording and mixing. Hardware monitoring, a blend control for live input versus computer playback, MIDI I/O, and driver loopback make it suited to tracking, routing computer audio, streaming, and podcast work.
