RME HDSPe AES
מיועד בעיקר להקלטות של מוסיקה קלאסית רבת ערוצים ברזולוציה גבוהה או לאולפנים בעלי דרישות גבוהות. לבעלי הממירים שיש להם יציאות דיגיטאליות מסוג AES הנה פתרון מבית היוצר של RME על כל המשתמע מכך, השעון Steady Clock, איכות העיצוב והדרייברים המדהימים. הכרטיס אינו מתבסס על "מתאם" PCI ל-PCIe (כלומר PCI to PCI Express bridge) אלא מתוכנן מחדש לניצול טכנולוגיית ה – PCIe החדשה – מה שבאופן ישיר מקפיץ את רמת הביצועים של הכרטיס פי 2 !
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 sensitive word clock input 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 AES' remarkable features include:
- Support for 192 kHz at full channel count
- Native support for Double and Quad Wire transfer
- Direct conversion between these formats
- SteadyClock for highest jitter suppression and clock regeneration
- Intuitive and clearly laid-out user interface
- TotalMix: 512 channel mixer with 42 bit internal resolution
- 48 level meter Peak/RMS, hardware-computed
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.
The Time Code Option can be used with the HDSPe AES to sync to LTC and video. Thanks to SteadyClock(TM), the TCO not only extracts absolute positions from LTC, but also a very clean low-jitter word clock from LTC and video.
The card's most important settings are stored on the card itself. Rather than operating in a default mode from the moment the computer is switched on until the driver is loaded, the card will immediately activate the last used sampling rate, master/slave configuration and AES format, thus eliminating any startup noise or problems in the clock network, both at system start and reboot.
An optional 19" breakout box is also available. Its innovative design features XLR I/Os that can be accessed from the front or rear in a rack, according to the user's choice. BOB-32 provides D-sub connectors with Tascam and Yamaha pinout, therefore can be used with other devices as digital rack breakout box as well.
The PCI Express interface of the HDSPe system is based on the PCI Express Base Specification v 1.1. It represents a 1-Lane PCI Express Endpoint Device and supports 2.5 Gbps line speed. Thanks to the packet-based full duplex communication, the card provides a transfer rate of up to 500 MB/s – 250 MB/s in every direction.
