Detailed Specifications
YEALINK 1303167 - AV over IP Encoder
Overview
The Yealink EN300 (MPN: 1303167) is a professional-grade AV over IP (AVoIP) transmitter engineered to encode and distribute high-definition media over standard 1Gbps enterprise networks.It addresses long-distance signal degradation and rigid matrix switching limits by utilizing low-compression encoding technology.This architecture delivers lossless 4K video at 60Hz with full 4:4:4 chroma sampling across local area subnets while maintaining ultra-low latency measured under a single frame.
The hardware features an integrated USB over IP bus to enable remote peripheral switching, allowing physical USB assets like conference room cameras, mice, or keyboards connected to a downstream decoder to pipe back directly into the host compute node. Input switching is managed natively via automated hardware negotiation across dual HDMI ports and a full-featured USB-C interface that supplies up to 45W of USB Power Delivery for laptop charging during wired BYOD/BYOM sessions. The unit includes native support for the Dante AV-A protocol and AES67 audio streams through on-demand software licensing. Do not deploy this transmitter on sub-Gigabit networks or standard unmanaged switches lacking IGMP Snooping capabilities, as multicast high-bandwidth 4K distribution will saturate non-optimized networking infrastructure.
Key Features
Lossless 4K60 video transmission maintains 4:4:4 color depth accuracy.
Integrated 45W Type-C port enables simultaneous casting and fast charging.
USB over IP routing bridges remote conference room peripherals seamlessly.
Embedded Dante AV-A protocol supports native network audio interoperability.
Automated hardware priority switching transitions between live media sources fast.
