Description
AMX NMX-ATC-N4321D-C Audio Transceiver Card
The N4321D is a compact, rack-mountable audio interface card that brings networked audio distribution into your venue or event space. This card slots directly into AMX control systems and handles Dante audio-over-IP conversion with minimal latency, making it reliable for live sound setups, permanent installations, and broadcast environments where you need dependable, standards-compliant audio routing without surprises.
Network Audio Architecture
Built around dual Gigabit Ethernet ports with auto-sensing capability, the N4321D gives you flexible network connectivity with one port supporting PoE+ power delivery, so you can eliminate separate power runs in many installations. Support for Dante, AES67, and streaming PCM protocols means you can integrate it with industry-standard networked audio gear and layer it into existing systems without compatibility headaches.
Audio I/O Configuration
The card delivers flexible routing with 2-channel balanced/unbalanced audio inputs, 2-channel Dante and AES67 inputs, and 8-channel PCM audio inputs on the input side. Output options include 2-channel balanced audio via 5-pin phoenix connector, 2-channel Dante/AES67 outputs, 8-channel PCM outputs, and a 2-channel unbalanced headphone jack, so you can adapt it to multiple analog and digital pathways across your audio network.
