RME Digiface AVB 256-Channel 192 kHz USB Audio Interface
Developed by RME, Digiface AVB is a glance into the future of audio network technology. The device uses AVB, an open protocol developed by the IEEE, to transfer up to 256 channels of audio between PC and audio network. An additional headphone output allows high quality monitoring.
Exploring New Ways to Transport Audio
RME’s Digiface AVB showcases how audio can be transferred from a Mac or PC into the network and back using the AVB protocol stack. It allows to send up to 128 audio channels for record and playback at 48 kHz / 24 bit sampling frequency and 64 channels at 96 kHz (128 channels I/O AVB) or 32 channels at 192 kHz with quad speed (64 channels I/O AVB).
Channels are organized in streams of configurable size from 2 to 32 channels, which enables connections to all available AVB audio devices on the market (comprehensive compatibility tests pending). The accompanying software package comprises an AVDECC controller, which provides essential functions to discover all AVB devices in a network and manage connections of incoming and outgoing streams.
Basic monitoring capabilities are built in. TotalMix FX enables comprehensive routing and monitoring options.
