PCX22HR STEREO SOUND CARD

Key Workflow: PCI play-only stereo sound card with on-board processing for on-air automation, and other mission-critical applications.

PCX22HR is the reference play-only stereo sound card with on-board processing designed for operating in continuous 24/7/365 use-environments, such as radio automation. Its on-board processing guarantees that audio is always processed whatever the PC CPU load is, which gives the system absolute reliability and responsiveness .

At a glance

PCX22HR is the play-only stereo model of the PCX series of sound cards. Thanks to its broadcast grade specifications, its on-board processing and unrivaled reliability, PCX22HR is the references stereo sound card used in radio automation applications designed by Development Partners, who use our appropriate software development kit (SDK) to benefit from all the on-board functionalities of the card. Available as part of the systems delivered by Digigram Development Partners, PCX22HR can also be used as a linear PCM sound card with software applications based on standard driver interfaces.
