Occupying only a single slot, the PCIe x4 interface transmits and receives up to 512 channels of network audio signals on two separate RJ45 connectors. The network audio channels can partially be replaced (or extended in case of the Milan® version) with MADI signals by adding up to two optional dual optical or dual coaxial extension cards. It is therefore possible to integrate four MADI input signals, four MADI output signals plus up to 256 network audio channels per direction within a single audio interface for the first time – on macOS and Windows.

In comparison to these massive channel counts, the ¼” stereo headphone jack occupies a lot of space on the card – for good reasons, because it allows monitoring of any signal reaching the card – from the computer, the network, or the optional MADI inputs. And to add one more signal to the mix – a stereo AES3 digital I/O is available together with MIDI on a breakout cable, making it a versatile and full-fledged professional interface.
