Multichannel Sound Card VX441e

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

VX441e is a professional linear (PCM) multichannel sound card based on the PCI Express bus interface. It is designed for use in any professional system running under Windows or Linux. It is a reference card in radio broadcast automation for applications such as automated recording and play-out and multichannel production.

At a glance

VX441e features four input and output channels through AES/EBU connectivity, with the possibility to synchronize on an external clock (AES11, Word clock, black burst video).  It can be used under Windows or Linux operating systems, with software applications based on standard driver interfaces such as DirectSound, Wasapi, and ASIO for Windows, and Alsa for Linux.

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