The VX442 from Digigram is a short-form PCI card, that provides four analog inputs and outputs, along with a one stereo digital I/O.
The analog I/Os can be set for either +4dBu or -10dBV, while the digital I/O is set for AES/EBU but can also be re-set to accept S/PDIF signals.
A comprehensive set of Windows and MacOS low latency drivers are provided, including DirectSound, Wave, ASIO, GSIF, EASI, SoundManager and Core Audio.
