The world of audio interfaces is rarely cross-platform when it comes to performance, meaning that Mac devices (using Thunderbolt) usually far outperform PC interfaces (using USB). While USB can be effective for two-channel designs, it requires more CPU overhead to manage, resulting in higher CPU usage and latency versus Thunderbolt – and the problem just gets worse as you add more channels. Unlike any other interface on the market, the VRS8 offers both Thunderbolt and PCIe connectivity for maximum cross-platform compatibility. The PCIe performance is the same as Thunderbolt, so you can decide for yourself which connection to use. You can also link up to 6 VRS8’s via Thunderbolt to achieve 48 inputs and outputs.
