The ExpressBox7 lets audio pros and others who need more flexible expansion space to add seven more cards to a Mac Pro. In coordination with a host controller card and interface cable, the ExpressBox7 adds seven full-length PCI Express card slots to a PCIe-equipped computer, including a Mac Pro. It also includes its own independent 500 watt power supply.
Power to individual card slots can be turned off and on without powering down the entire system, and the host controller card is a low-profile model that doesn't obstruct other cards or slots. The ExpressBox7 supports peer-to-peer transfers between cards in slots, and can accommodate optional redundant power supplies to share load during normal operation and operate as a backup in the event of a power supply failure.
Pro Tools HD is Digidesign's professional Digital Audio Workstation (DAW) used in music studios, post production and broadcast facilities, edit suites and mobile production environments. It combines virtual instrument and sound processing plug-in software with Digital Signal Processor (DSP) cards and audio input/output interfaces.
Magma's ExpressBox7 Web page still indicated "Digidesign qualification pending" as Macworld posted this article, but a press release from Magma confirms that the qualification has been done.
