Overview
Routing dozens of line level channels between a computer, outboard gear and other interfaces is what this MOTU unit handles over Thunderbolt or USB-C. Built-in DSP mixes and processes signals, and virtual patch cords route any source to any destination.
High channel count, very low latency and AVB networking let one box anchor a large studio or a distributed live system. Effects and monitor control live on the unit. Every analog input is line level, so microphones need separate preamps.
Who it's for
Mix engineers, post production rooms and live sound teams running many line inputs and networked rigs get a compact, deep routing hub. Singer songwriters wanting plug in mic inputs will find nothing to plug a mic into.
Pros and cons
- Very high channel count
- High dynamic range converters
- Very low round trip latency
- Onboard DSP mixing and effects
- No microphone preamps
- IPad Lightning adapter sold separately
- DSP effects limited at the highest sample rates
Performance notes
Converter quality sets the noise floor, while MOTU drivers and the Thunderbolt link determine round trip latency for live monitoring through a DAW. The DSP mixer runs effects on the unit, which spares the computer's processor.
