Bring Single-Cable USB-C Connectivity to NAV Pro AV over IP Systems

Posted on 20 October 2026

NAV E 522 and NAV SD 521

Introducing the NAV E 522 two-input switching encoder and NAV SD 521 scaling decoder, powerful AV over IP endpoints that deliver flexible signal distribution, switching, scaling, and USB extension over standard 1 Gbps IP networks. Designed for modern meeting, collaboration, and presentation environments, these new endpoints simplify connectivity while expanding the capabilities of NAV systems.

The NAV E 522 switching encoder brings single-cable USB-C connectivity to the NAV System, enabling video, audio, USB data, and optional device charging to be delivered between a USB-C host device and the encoder. By combining USB-C AV input, USB host connectivity, and power delivery in one encoder, the NAV E 522 provides a clean and streamlined laptop connection experience.

Another key advantage of the NAV E 522 is its ability to support multiple NAV SD 521 scaling decoders, each connected to USB 2.0 peripherals such as cameras, microphones, DSPs, touch displays, HID devices, and other USB equipment. These devices can all be made available to a single USB-C host connected to the NAV E 522, creating a seamless room experience in which one laptop gains access to distributed AV resources and remote USB devices throughout the NAV system.

Additionally, the NAV E 522 switching encoder includes an HDMI input and USB-C host interface for added flexibility. The NAV SD 521 complements the encoder with local HDMI input switching, decoding, scaling, and USB 2.0 or HID extension, while also providing power to USB devices. Support for AES67 audio over IP enables integration with Extron DMP Plus DSPs and other networked audio components. As part of the highly scalable NAV platform, the NAV E 522 and NAV SD 521 are purpose-built for demanding professional AV environments and secure deployment of AV signals to thousands of endpoints.
