PCX881e MULTICHANNEL SOUND CARD
Key Workflow: PCI Express multichannel sound card with on-board processing for on-air automation, production, permanent playback and recording .
PCX881e is the reference multichannel sound card with on-board processing designed for operating in continuous 24/7/365 use-environments, and fully digital systems, such as radio automation. Its on-board processing guarantees all audio channels are always processed whatever the PC CPU load is, which gives absolute reliability and responsiveness to the audio system.
At a glance
PCX881e is the full featured multichannel model of the PCX series of sound cards. Thanks to its broadcast grade specifications, its on-board processing and unrivaled reliability, PCX881e is the references multichannel sound card used in the radio automation systems designed by Digigram Development Partners. A proprietary Software Development Kit (SDK) allows control of the card’s on-board functionalities. Available as part of the systems delivered by Digigram Development Partners, PCX881e can also be used as a linear PCM sound card with software applications based on standard driver interfaces.
