VX822e – Multichannel PCM Sound Card

Linear PCM multichannel stereo sound card for professional playout audio workstations. VX822e is a professional linear (PCM) multichannel sound card based on the PCI Express bus interface. It is designed for use in demanding applications such as broadcast radio live-assist, permanent playback, multichannel playback, running under Windows and requiring balanced analog and AES/EBU connectivity.

At a glance

VX822e features eight output and two input channels available through balanced analog and AES/EBU connections, and can synchronize on an external clock (AES11, Word clock, black burst video). It can be used under Windows with software applications based on standard driver interfaces such as WDM Kernel streaming, DirectSound, Wasapi, and ASIO for Windows
