About PCI Interfaces


The PCI audio interface has simplified the way we recording engineers make music. No external audio interface required; simply connect a mic or instrument directly to your machine when inspiration strikes, and you’ve got all you need to churn out some serious bedroom bangers.


Why the PCI Interface Still Rocks


While the beauty of the PCI audio interface has to be its tracking and monitoring simplicity, these aren’t its only calling cards. Installing a Focusrite RedNet PCIeNX on your machine, for instance, nets you a massive 128 tracks of I/O over Ethernet. Then there’s the Universal Audio UAD-2 OCTO Core PCIe card, which gives you a native 8-core SHARC processor for running even more of the UAD plug-ins you love when you’re mixing on the road.


Video producer? Check out what a product like the Blackmagic DeckLink Quad brings to the table. Paired with the included Blackmagic software, this PCIe card features ports for four 4K video sources using full-size HDMI connectors. That’s a lot of throughput for not needing an external capture card.
