The BG-EXH-70C 4K HDMI extender can transmit an uncompressed [email protected] HDMI signal with zero latency at distances up to 70 meters. By utilizing a Cat6/6A/7 network cable this extender allows a signal to be transmitted farther than is possible using standard HDMI cables. Digital audio extraction for an external audio system can be done via the S/PDIF port and supports LPCM, DTS-HD, DTS-Audio, Dolby Digital, and Dolby TrueHD audio formats. With a flip of the switch, choose ARC for returning audio from compatible displays. The HDMI loop-out allows for an additional display on the transmitter side. Plug and play setup, bi-directional IR pass-through, and surge protection ensure easy setup, flexibility, and reliability.
