A single HDBaseT Matrix switch pairs with 12 HDBaseT receivers to transmit HDMI signals and bi-directional IR up to 230 feet with full 1080p video and support for Dolby TrueHD and DTS-HD Master audio. Although HDBaseT transmission technology is much less susceptible to EMI interference than other transmission technologies, if possible, it is recommended that you pull shielded Cat5e/Cat6 with this product for maximum reliability. Please note: for proper shielding, shielded connectors must be used with drains connected at both ends. In addition, “EZ end” connectors are not recommended for use with HDMI extenders.
