The Allen & Heath GPIO Interface is a compact, PoE-enabled half-rack unit providing 8 general-purpose inputs and 8 relay outputs for integration with external control systems. Ideal for custom installations using dLive, Avantis, or AHM systems, the GPIO interface enables contact closures, LED indicators, switch triggers, and more. Its robust design and flexible connectivity make it perfect for paging, zoned audio control, or complex AV automation in commercial, house of worship, or education environments.
