As a complete end-to-end solution, the VE1821 comes as a kit that contains a transmitter and a receiver, extending HDMI signals at 4096 x 2160 / 3840 x 2160 @ 30 Hz (4 : 4 : 4) up to 40 m via a Cat 6 cable (ATEN 2L-2910 recommended). Crystal-clear video presentation is guaranteed thanks to its capability of transmitting 4K sources without latency. Meanwhile, it supports lossless audio formats, such as LPCM 7.1CH, Dolby TrueHD, Dolby Digital Plus, and DTS-HD Master Audio, to add superior sound to the video content, enhancing the experience for the viewers.
Designed to optimize installation flexibility, the VE1821 features an ultra lightweight, palm-sized enclosure, perfect for mounting or placement in tight spaces. The transmitter includes a local HDMI output port, allowing for cascading purposes or for users to monitor the UHD signal being extended to the receiver. With the built-in EDID switch, users can control which EDID is taken from either display. Plus, the HDMI source can be displayed at the optimal resolution based on the capabilities of the connected display through the EDID Copying Mode. As a result of the IR transmission functionality, the source device connected to the transmitter can be seamlessly controlled from the receiver side, assuring easy and complete control for the user. The VE1821 adopts PoC (Power over Cable) technology, which enables the transmitter to provide power to the receiver via a Cat 6 cable, eliminating the need for a bulky external power supply.
With such a rich set of features, the VE1821 delivers excellent AV transmission quality and flexibility within different installation scenarios, such as meeting facilities, retail settings, entertainment systems, and more.
