Digigram VX222 MkII 24-Bit Stereo PCI Audio Interface

This high quality, versatile sound card includes balanced analog inputs and outputs with 24-bit converters, as well as digital input/output in AES/EBU or S/PDIF formats. Special features include two General Purpose Interface (GPI) inputs and outputs. The VX222v2 can team up with a wide choice of audio applications using Microsoft's Wave and DirectSound protocols, Apple's SoundManager and CoreAudio, Steinberg's ASIO, or Linux ALSA. Support of Digigram's Virtual PCX makes it easy to integrate with applications created by Digigram's development partners.
