VX881HR MULTICHANNEL PCM SOUND CARD

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

VX881HR is a professional linear (PCM) multichannel sound card based on the PCI 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

VX881HR features  eight input and output channels and offers balanced analog and 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 WDM Kernel streaming, DirectSound,  Wasapi, and ASIO for Windows, and Alsa for Linux.

  • Developed for the broadcast industry
  • Supports balanced analog and AES/EBU audio
