Distribute a single SD or HD signal to up to four displays with this KanexPro 1x4 HDMI Distribution Amplifier and Cat5e/6 Extender Kit. The simple wiring and long transmission distances work well for conventions, events, houses of worship, and digital signage. This kit consists of a main transmitter hub which connects to the video source, and four receivers that connect to standard HDMI displays. Standard, readily available Cat5e or Cat6 cables connect the transmitter and the receivers to distances up to 398', much longer than standard HDMI cables, without any signal integrity loss. IR receiver kits are included to maintain remote control of your video source. The wall-mountable design allows the included units to retain a low profile for installation.
