Grace Design m701 32×32 Digilink Audio Interface

The Grace Design m701 32×32 Digilink is a high-channel-count modular audio interface designed for professional studios running Avid Pro Tools HDX and Digilink-based workflows. Built around Grace Design’s reference-grade AD/DA conversion, the m701 provides an exceptionally transparent, musical signal path while offering the flexibility to scale from modern hybrid rooms to large-format recording and post-production facilities.

At its core, the m701 is a configurable platform built to adapt to real-world studio needs. Eight internal card slots support Grace Design’s 8-channel AD and DA modules in any combination, allowing the system to be tailored for tracking-heavy, mix-centric, or hybrid analog/digital workflows. The 32×32 Digilink configuration enables direct integration with Pro Tools HDX systems while maintaining access to the m701’s extensive onboard digital I/O and internal routing capabilities.

Grace Design’s decades of experience in analog circuit design, power supply engineering, and clocking are fully realized in the m701. While modern converter chips have largely standardized performance, the surrounding analog stages are where the m701 distinguishes itself—delivering open, detailed, and highly musical conversion suitable for critical tracking, mixing, and mastering applications. A built-in 32×8 low-latency cue mixer further enhances workflow efficiency, allowing artists to access personalized cue mixes via GraceNet on phones or tablets without additional software.

The m701 is housed in a robust 2U chassis with a dual redundant power supply and ultra-quiet cooling system, making it well suited for demanding professional environments. GraceNet browser-based control is built in, requiring no software installation, and provides comprehensive system configuration, metering, and routing from any modern device. With a five-year transferable warranty and a forward-looking modular architecture, the m701 32×32 Digilink is engineered for long-term reliability and studio growth.
