The 1212M V3 PCIe Digital Audio System is a PCI Express version of E-Mu's Digital Audio System. The 1212M V3 offers a new high speed PCI Express 1 lane interface that can run at 400 megabytes per second and can transfer data 4 times faster than standard PCI in both directions simultaneously. E-MU's 1616M PCI Digital Audio System delivers everything you need to produce audio on a PC with professional results- 24-bit/192kHz converters (the same A/D converters used in Digidesign's ProTools HD 192 I/O interface), hardware-accelerated effects and mixing, comprehensive sync options and seamless compatibility with your favorite PC audio/sequencer software. Pros: It can do 5.1 in 48KHz for DVD playback, 192KHz for sacd playback using I/O ports. I have been using E-MU products for very long time, 1212m/1820m/1616m(pci and card bus), PM5(monitor), and PS12(sub), and very happy. Cons: 5.1 playback need manually route the individual channel. So for ordinary users do take time to make it work.
