RME DIGIFACE AVB 256-Channel 192-Kilohertz Mobile ABV/TSN Audio Interface

Expand your audio network's channel count with the RME Digiface AVB, a 256-channel mobile AVB/USB audio interface designed to streamline the transfer of digital audio between your Mac or Windows computer and an AVB network. Ideal for broadcast, theatre, and large-scale concert production, the Digiface AVB supports resolutions up to 24-bit / 192 kHz, and a maximum of 128 channels in and out.

Hookup is simple; just plug the RJ45 Gigabit Ethernet port into your AVB network, then connect the USB 3.1 Gen 1 port to your host computer. Utilize the BNC wordclock I/O for proper synchronization with other digital audio devices such as mixers or a master clock. A 1/4" TRS line/headphone output allows convenient monitoring of an independent submix for easy assessment of signal quality. The USB-powered Digiface AVB includes a powerful software bundle offering comprehensive mixing, control room functions, remote control, measurement, analysis, and more.
