Digigram LoLa881 Multichannel PCM Sound Card with 4 Stereo AES/EBU I/O

LoLa881 and LoLa881-SRC are professional linear (PCM) multichannel sound cards based on the PCI Express bus interface. They are designed for use in any professional system running under Windows or Linux, and requiring up to four AES/EBU I/O connections. They are reference cards in radio broadcast automation for applications such as multichannel audio ingest, play-out, and production.

LoLa881 and LoLa881-SRC cards feature eight input and output channels through AES/EBU connectivity, with the possibility to synchronize on an external clock (AES11, Word clock, black burst video). LoLa881-SRC can in addition handle asynchronous AES/EBU input signals thanks to its high quality hardware sample rate converters on each AES/EBU input. LoLa cards allows for very low latency operations, and 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.
