Brief

The AS2-OEM is a 10-port Ethernet switch optimized for audio and video networking. Featuring AVB and TSN standards, it includes eight RJ45 ports (100 Mbit/s and 1 Gbit/s PoE+) and two SFP cages for fiber or copper connections. Powered by JOYNED’s AVB software stack, it ensures seamless integration, Avnu certification support, and robust performance for live sound, studio production, and commercial AV installations. This board is ready to be integrated into a product with either internal or external PSU. It includes connectors for adding GUI elements, temperature monitoring, FAN control etc.

The AS2-OEM is a 10-port Ethernet switch engineered for audio and video networking. It integrates Audio Video Bridging (AVB) and Time-Sensitive Networking (TSN) standards for deterministic, low-latency data transmission. Eight ports feature RJ45 connectors supporting 100 Mbit/s and 1 Gbit/s Ethernet with Power over Ethernet (PoE), while two additional ports are equipped with SFP cages for modular fiber or copper connections.

This switch is ideal for time-critical AV installations, such as live sound, studio production, and commercial AV installations.
