The main board contains the Wordclock I/O and a 25-pin D-sub connector that provides 4 AES inputs and 4 AES outputs (8 channels each) via a standard digital breakout cable that conforms to Tascam's pinout. The Wordclock input operates on single, double and quad speed signals automatically. The expansion board does not require an additional PCI slot and adds channels 9-16 and a connector for a MIDI breakout cable with 2 MIDI I/Os (4 x 5-pin DIN connectors).

The card is not based on a PCI to PCI Express bridge, but is a genuine PCI Express solution, which takes full advantage of the format, providing significant performance gains in multi-track audio with lower latency over previous formats. The HDSPe AES-32 is a perfect all-in-one solution for users in the fields of broadcast, TV, theater, stage/PA and in any professional studio.

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
