The PCIe-424 card allows you to run your MOTU PCI core system on any Mac or PC equipped with a PCIe ("PCI Express") slot, as found in most current-generation tower PCs and Apple's latest Dual-Core Power Mac G5 and Intel Mac Pro towers.
If you are upgrading from a PCI-324 card, the PCIe-424 card adds many additional new features over the original PCI-324 card, including:
- A fourth Audio Wire port - lets you connect a fourth MOTU PCI audio interface to your system. Depending on your I/O configuration, this allows you to have up to 96 inputs and outputs at 96 kHz on a single card system!
- CueMixDSP™ - a powerful processor dedicated to creating a custom tailored monitor mix of up to 96 channels of 96kHz audio. Because the mixing takes place on the card itself, instead of making the round trip from the PCI bus to the host processor, the PCIX-424 system provides the same near-zero latency performance as today's latest digital mixers. CueMix DSP completely eliminates the buffer latency associated with monitoring on host-based systems. Because the DSP is mixing for you, your computer's CPU is free for other tasks.
NOTE: If your computer is equipped with PCI Standard (5 volt) or PCI-X (3.3 volt) slots, DO NOT purchase this PCIe-424 card and instead purchase the PCIX-424 card.
