RME HDSPe AoX-M 512-Channel PCI Express Card.
The HDSPe AoX PCIe x4 audio interface cards combine dual network ports with headphone output, AES3, MIDI, and internal expansion headers for up to four MADI ports. Whether used in a Thunderbolt expansion chassis or built into DAWs or audio processors, these cards send and receive up to 512 channels of audio and provide numerous mixing and routing capabilities.
- 2x Gigabit Ethernet (802.3 compliant)
- 1x AES/EBU I/O
- 1x Phones Output
- 1x MIDI I/O
- TotalMix FX
- ARC USB
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.
Flexible Mixing & Routing with TotalMix
The vast number of channels can be managed by the user in two steps. Using a driver dialog or web interface, the user first adjusts the network vs. optional MADI channel count, and then pre-selects which inputs reach the 256 channel TotalMix engine. The remaining 256 channels are passed straight through. All 512 channels are visible to the DAW for recording. TotalMix offers its basic functionality without effects, but with all the great benefits such as presets, layouts, loopback, sub-mixes, and many more.
The card can be installed in external Thunderbolt enclosures as a perfect addition to mobile recording setups, or installed in common DAWs or audio processors.
More Outstanding Features
- TotalMix FX - Mixing/Routing with superior features for Studio and Live Work: Since 2001 TotalMix added unlimited routing and mixing to RME‘s audio interfaces. Its unique capability to create as many independent submixes as output channels available turned it into the most flexible and powerful mixer of its kind.
- About MADI - Multi Channel Digital Audio Protocol: MADI is a protocol that has evolved alongside RME to be the most widely accepted multi channel digital audio protocol on the market. RME’s MADI-based systems deliver incredible reliability, particularly in applications where failure is not an option.
