The RME HDSPe AoX-D card sets a new benchmark for high-performance audio interfaces. Available as Dante with 512 x 512 channels, this card leverages RME’s renowned driver architecture to bring high channel counts to any DAW. They also feature a 256-channel TotalMix™ engine, RME’s FPGA-based super low-latency hardware mixer.

High Channel Count and Connectivity

Occupying only a single slot, the PCIe x4 interface transmits and receives up to 512 channels of network audio signals on two gigabit Ethernet ports. You can integrate four MADI input signals, four MADI output signals, and up to 256 network audio channels per direction within a single audio interface for the first time – on macOS® and Windows®. The network audio channels can be partially replaced or extended with MADI signals by adding two optional dual optical SFP or dual coaxial extension cards.

Monitoring and Versatility

The ¼” stereo headphone jack allows engineers to monitor any signal reaching the card from the computer, the network, or the optional MADI inputs. A stereo AES3 digital I/O and MIDI are also available on a breakout cable, making this a versatile and professional interface. A word clock input/output port is available on the MADI option cards.

Managing High Channel Counts

The driver’s software dialogue includes a routing matrix that creates the connections between hardware I/O and software I/O, offering flexibility. Users select which 256 channels to send to TotalMix, which provides features such as level metering, preset management, layouts, sub-mixes, and loopback. An additional 256 channels can be passed straight through to the DAW, making 512 channels visible for recording. Users then select which channels should be sent to the card’s hardware outputs. Higher sampling rates reduce channel counts: half at 96 kHz and a quarter at 192 kHz, except for the Milan version, which supports 128 channels at 96 kHz and 64 channels at 192 kHz.

Installation Flexibility

Both cards can be installed in external Thunderbolt™ enclosures, making them perfect additions to mobile recording setups, common DAWs, and audio processors.

Optional: MADI I/O Expansion Cards

Expand the RME HDSPe AoX-M with up to two RME AoX MADI Expansion Cards, available with coaxial BNC connectors or optical SFP modules:

• RME-AOX-MADI-EXT-BNC (2 x MADI I/O Coaxial BNC + 1 x WordClock BNC)
• RME-AOX-MADI-EXT-SFP (2 x MADI I/O Optical SFPs + 1 x WordClock BNC)
