INTRODUCTION
Thanks for choosing the professional 8x8 HDMI 2.0 HDBaseT matrix switcher! 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 230 feet (70 meters) over a single CATx Ethernet cable. The eight
HDBaseT outputs support 24V Power over Cable (PoC) feature, allowing the compatible
receivers to draw their power from the matrix over the HDBaseT cable.
The matrix switcher features comprehensive EDID management and advanced HDCP handing to
ensure maximum functionality with a wide range of video sources.
The matrix switcher 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.
FEATURES
8x8 HDBaseT matrix switcher with audio matrix.
Fully compliant with the HDMI 2.0 and HDCP 2.2.
Supports HDMI resolution up to 4K@60Hz 4:4:4, HDR10.
Features eight mirrored HDMI outputs for eight HDBaseT outputs, and the eight HDMI
outputs support 4K to 1080p down-scaling.
The eight HDBaseT outputs support 24V PoC, allowing the receivers to draw their power
