RME HDSPe AES 32-Channel AES/EBU PCIe Audio Interface

The HDSPe AES 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 card 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 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.

The DSP-based TotalMix mixer enables the AES to route and mix all 16 inputs and 16 playback channels to all 16 physical outputs freely, offering extraordinary monitoring capabilities. Up to 8 fully independent stereo submixes can be created. Routings can be copied and pasted, faders ganged and grouped, which, along with the amazing matrix window, turns the AES into a powerful and easy-to-use redistributor, patchbay, router, converter, and splitter. The hardware-based mixer is fully MIDI-controllable. Furthermore, the DSP hardware calculates RMS and peak level meters for all 48 audio channels, with no measurable CPU load.
