KONA LH is available in two models that differ only in their bus interface. The KONA LHe model has a PCIe interface (PCI Express four lane x4) for use with the latest PCIe Apple Power Macs. The KONA LH model is a PCI card that plugs into a PCI-X G5 chassis (it requires a minimum PCI 66/64 slot). Both models work with Final Cut Studio and other applications to provide a professional editing suite, corporate/industrial video center, or high-powered desktop video setup. Same features, same LH driver software, same wonderful price—the choice is your's.
