The RME HDSPe AES 32-Channel 24 Bit/192 kHz AES/EBU I/O is a short-length PCI Express card with AES/EBU interfaces. It provides eight AES inputs (16 channels) and eight AES outputs (16 channels) at 192 kHz sample rate.

The RME HDSPe AES is also equipped with two MIDI I/O ports, word clock I/O, and can be used with the optional TCO module for synchronization to LTC and video.

The RME HDSPe AES is RMEs reaction to requests from audio professionals for an AES-based solution with the typical RME features and quality. This audio card is a perfect all-in-one solution for professional users in the fields of broadcast, TV, theater, stage/PA - and in any professional studio.

The card's mainboard contains word clock I/O and a 25-pin D-sub connector, providing four AES inputs and four AES outputs via standard digital breakout cable (Tascam pinout). The word clock input is galvanically isolated via transformer and operates on Single, Double and Quad Speed signals automatically. The expansion board adds audio channels 9-16 and a connector for a MIDI breakout Cable with two MIDI I/Os (four 5-pin DIN connectors). It does not require a PCIe slot.

The card is not based on a PCI to PCI Express bridge, which would simply add PCIe to existing PCI technology. It is a newly developed genuine PCI Express solution, which consequently takes full advantage of the new format, achieving significant performance gains in multitrack audio and lowest latency.
