The TOA N-8000AF CU is a dedicated audio function interface unit built for integration within TOA's N-8000 Series IP packet intercom system. It bridges the gap between IP network audio and legacy analog infrastructure by providing a transformer-isolated balanced audio input and output, eight contact inputs, eight relay contact outputs, and a dedicated time synchronization input. Audio engineers and system integrators working in facilities that require scheduled chime broadcasts, automated paging triggers, or conversation recording will find this unit addresses those requirements directly within a managed IP intercom architecture.

Typical deployment scenarios include campus PA systems, healthcare facilities, transportation hubs, and corporate campuses where automated time signals, code alerts, or zone paging must run on a reliable schedule. The built-in timer supports up to 16 programmable time schedules for chime and broadcast events, eliminating the need for external scheduling hardware. The unit connects via standard RJ45 to a 10BASE-T/100BASE-TX network and supports both unicast and multicast paging to up to 191 destinations simultaneously, making it practical for large, distributed intercom topologies.

Where generic audio interface boxes require third-party controllers for contact-triggered events, the N-8000AF CU handles contact logic internally, with each relay output rated for 24 V DC operation and each contact input requiring no external voltage source. Installation flexibility covers rack mounting in a 1U EIA bay using an optional bracket, desk placement on the included plastic feet, or surface wall mounting with an optional bracket. The front-panel reset switch and onboard status indicators support in-field diagnostics without requiring a laptop connection for routine checks.
