HDSPe AoX-M

The RME HDSPe AoX-M is a forward-thinking PCI Express audio interface engineered for high-end audio networking based on the deterministic Milan protocol. This card is designed for professionals in live sound, broadcast, and installation who require the guaranteed interoperability and time-sensitive delivery of the Milan standard. Combining this next-generation AVB-based protocol with the industry-standard MADI format, the HDSPe AoX-M provides an unprecedented 512 input and 512 output channels on a single PCIe 3.0 card. It delivers the massive channel count, ultra-low latency, and unwavering stability that RME is known for, making it a cornerstone for any large-scale, future-proofed audio network.

The interface provides 256 channels of Milan audio I/O through two redundant Gigabit Ethernet ports, ensuring reliable performance and compatibility with all Milan-certified devices. In parallel, it offers 256 channels of MADI I/O via two optical SFP modules, allowing for seamless integration with legacy MADI equipment or for expanding the system's channel count. The heart of the HDSPe AoX-M is its powerful FPGA, which hosts the TotalMix FX digital mixer. This allows for complex, latency-free routing and mixing of all 1024 channels directly on the hardware, independent of the host CPU. RME's latest SteadyClock Pro technology is also integrated, providing reference-level clocking and jitter rejection for pristine audio quality across the entire network.
