Specifications
The ST-NED970C HDMI Extender transmits uncompressed, zero-latency HDMI video, professional audio, and IR control signals over a single CAT5e/CAT6 cable up to 70m at 1080p and 40m at 4K30. The ST-NED970C HDMI Extender features one-way Power over Cable (PoC), HDMI loop output, EDID copy, IR pass-through, and commercial-grade ESD protection, making it ideal for professional AV installations.
The ST-NED970C HDMI Extender is a plug-and-play solution for conference rooms, classrooms, digital signage, control rooms, home theaters, and commercial AV systems.
Features
☆ Extends HD audio/video signals up to 230ft/70m at 1080p, or 131ft/40m at 4K30 over a single CAT6 cable
☆ Uncompressed zero-latency point-to-point transmission
☆ HDMI local loop output on Transmitter for local monitoring or cascading
☆ One-way POC — only the Transmitter requires 12V/1A power; current travels over the CAT cable to power the Receiver
☆ Physical EDID DIP switch for instant EDID cloning from local loop-out screen or remote receiver display
☆ One-way IR pass-through via 3.5mm IR IN/OUT for remote source device control
☆ Multi-channel audio support: LPCM 2.0/5.1/7.1ch, Dolby Digital, DTS 5.1, Dolby TrueHD, DTS-HD Master Audio
☆ Industrial ESD protection: ±8kV (Air-gap discharge), ±4kV (Contact discharge)
The ST-NED970C HDMI Extender is ideal for conference rooms, meeting rooms, classrooms, digital signage, home theaters, surveillance systems, control rooms, and other professional AV installations requiring reliable long-distance HDMI transmission with zero latency and IR control.
