VX222e STEREO PCM SOUND CARD
Key Workflow: Linear PCM stereo stereo sound card for professional stereo audio workstations
VX222e is a professional linear (PCM) stereo sound card based on the PCI Express bus interface. It is designed for use in any professional PC-based audio system running under Windows or Linux and requiring balanced analog and AES/EBU connectivity.
At a glance
VX222e is the reference stereo PCM sound card designed for operating in continuous 24/7/365 use-environments as part of professional audio systems. It can be used under Windows or Linux operating systems, with software applications based on standard driver interfaces such as WDM Kernel streaming, DirectSound, Wasapi, and ASIO for Windows, and Alsa for Linux.
