WyreStorm NHD-400-E-TX

The Wyrestorm NHD-400-E-TX encoder offers stunning 4K HDR video, multichannel audio support and 4K/2K scaling to seamlessly handle mixed resolution HDMI sources for matrix and video wall functionality. The reduced cost Type E version removes some control ports but retains the 400 Series core features. Featuring incredible low latency the 400 Series is the ideal AV over IP solution for systems where high quality and low delay are key requirements, making it perfect for demanding commercial applications. The NHD-400-E-TX JPEG 2000 encoder is intended for use with any 400 Series JPEG 2000 decoder (sold separately) to provide a complete end-to-end video distribution system. When used in conjunction with the NHD-000-CTL system controller complete control integration is quick and simple.


Delivering visually lossless 4K UHD content with HDR and HDCP 2.2 support the 400 Series ensures compatibility with the latest UHD video sources, while a built-in scaler at the decoder ensures hassle-free mixing of the latest 4K displays and 1080p screens within an installation.


Supporting traditional video walls, as well as customizable mosaic styles, perfect for building captivating & creative digital signage. JPEG2000 encoding ensuring distribution integrity and video latency of less than a single frame makes the 400 Series ideal for live environments.


Dynamic video processing seamlessly converts and matches source video content from each decoder to connected displays, removing video resolution and timing incompatibilities that might otherwise exist for reliable and easily manageable multi-display systems.


The 400 Series boasts discrete audio stream routing, ensuring true signal breakaway can maximize system flexibility. CEC and RS-232 display control signals can also be generated at the 400 Series decoder, removing the requirement for external equipment.


This WyreStorm Pro AV product comes with a 5 Year Warranty
