Description

The RME Digiface AVB is a high-performance 256-channel USB 3.0 audio interface designed to bridge your computer and AVB (Audio Video Bridging) networks with exceptional speed, flexibility, and reliability. Using the open IEEE AVB protocol, it supports up to 128 channels of simultaneous input and output at 48 kHz, scaling to 64 channels at 96 kHz or 32 channels at 192 kHz, ensuring compatibility with a wide range of professional workflows.

Its Gigabit Ethernet connection handles all network audio traffic, while a dedicated headphone output with DC-coupled design enables direct, high-quality monitoring. RME's TotalMix FX software provides comprehensive routing, monitoring, and control without channel count limitations, and integration with TotalMix Remote allows complete system control from iOS, PC, or Mac anywhere on the network. The included AVDECC controller simplifies device discovery and stream management, making it easy to connect with other AVB gear.

Robust build quality, word clock I/O, ARC USB support, and RME's renowned low-latency drivers make the Digiface AVB a powerful hub for studio, live sound, or broadcast environments adopting network-based audio systems.
