Grace Design m701 32×32 USB Audio Interface

The Grace Design m701 32×32 USB is a high-channel-count modular audio interface designed for modern native DAW studios that demand uncompromising audio quality, flexible routing, and scalable system architecture. Built around Grace Design’s reference-grade AD/DA conversion, the m701 delivers exceptional transparency, depth, and musicality while supporting complex hybrid analog and digital workflows without locking users into a fixed format.

The m701’s modular design allows studios to configure exactly the I/O they need today while remaining adaptable for future expansion. Eight internal card slots support Grace Design’s 8-channel AD and DA modules in any combination, enabling up to 64 channels of analog I/O. The 32×32 USB configuration provides high-channel-count USB connectivity for native DAWs, making it an ideal solution for tracking, mixing, and production environments that rely on USB-based workflows without sacrificing performance or reliability.

Grace Design’s long-standing expertise in analog circuit design, clocking, and power supply engineering is central to the m701’s performance. While modern converter chips are widely available, the surrounding analog stages are where the m701 distinguishes itself, delivering an open, natural sound that translates accurately across monitoring environments. A built-in 32×8 low-latency cue mixer allows multiple artist headphone mixes to be created and controlled independently, with direct access via GraceNet from phones or tablets.

Housed in a rugged 2U chassis, the m701 is engineered for continuous professional use with a dual redundant power supply and ultra-quiet fan cooling. Configuration and operation are handled via the front panel or GraceNet, Grace Design’s browser-based control platform that requires no software installation. With a five-year transferable warranty and a future-ready modular architecture, the m701 32×32 USB is a powerful centerpiece for modern production studios seeking premium conversion and long-term flexibility.
