Focusrite Scarlett 2i2 3rd GEN
Digigram VX442e
Features
|
VX442e 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
VX442e features four 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.
