About the MOTU 1248
The MOTU 1248 strikes a balance between analog connectivity and digital expansion, offering four premium mic preamps, six analog outputs, and two banks of ADAT optical for up to 32 channels of I/O. Thunderbolt, USB, and AVB networking provide flexible computer and network connectivity, while the onboard 48-input DSP mixer with EQ, dynamics, and reverb handles monitor mixing without loading the host. A versatile centerpiece for medium-scale playback and IEM rigs that need both analog I/O and digital expansion.
32-ch Thunderbolt/USB/AVB interface with 4 mic pres and DSP mixing.
