1. Product Introduction
Thanks for choosing our professional 8x8 Matrix with eight Receivers! The matrix is an
eight-input by eight-output HDBaseT and HDMI matrix with HDCP 2.2 and up to
4K/UHD@60Hz video support. It transmits 4K video to distances up to 131 feet (40
meters) and 1080p video to distances up to 229 feet (70 meters) over a single CATx
Ethernet cable. HDBaseT outputs support the Power over Cable (PoC) feature,
allowing the receivers to draw their power from the matrix over the HDBaseT cable.
The matrix features comprehensive EDID management and advanced HDCP handing
to ensure maximum functionality with a wide range of video sources.
The matrix not only supports bi-directional IR, RS232 extension but also has IR,
RS232, and TCP/IP control options.
The product provides performance in control and transmission, which could be used in
a number of different installation scenarios, for example, with computers, for monitoring
purposes, large screen displays, conference systems, television education, bank
security institutions, etc.
