Digigram VX820e

Key Workflow: Linear PCM multichannel stereo sound card for professional playout audio workstations.

VX820e 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 connectivity.

At a glance

VX820e features eight balanced analog output channels and two balanced analog input channels. 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:

  • Developed for the broadcast industry
  • Balanced analog audio connectivity
  • Interoperable with most third party software applications for audio production, under Windows and Linux
