tvONE 1T-CT-647 – 7-Port HDBaseT Transmitter
Product Overview
The tvONE 1T-CT-647 is a seven-port HDBaseT-Lite transmitter designed to distribute uncompressed HDMI signals to up to seven 1T-CT-642 receivers simultaneously over standard Cat.5e or Cat.6 cable. Supporting HDMI v1.4 with 4K UHD and 3D formats, it delivers full 1080p/60Hz signals at distances up to 60 meters (197 feet) per output without signal degradation. Embedded lossless audio formats including Dolby TrueHD and DTS-HD Master Audio are passed transparently through the system. This unit is the distribution hub of choice for multi-display installations requiring centralized HDMI signal management.
Product Description
The 1T-CT-647 operates using HDBaseT-Lite (Class B) technology to fan out a single HDMI source to seven independent outputs, each capable of driving a paired 1T-CT-642 receiver up to 60 meters away. Because it uses existing Cat.5e or Cat.6 infrastructure, installation costs are significantly lower than running individual HDMI cables to each display. The transmitter supports the full HDMI v1.4 feature set, including 4K UHD at 24Hz and 30Hz, 1080p at 60Hz with 36-bit deep color, 3D formats, and PC resolutions up to WUXGA. DVI sources can also be connected using standard HDMI-to-DVI cable adapters. Audio support covers embedded LPCM 7.1CH, Dolby TrueHD, Dolby Digital Plus, and DTS-HD Master Audio — all passed without re-encoding. HDCP 1.1 compliance and CEC bypass are included, ensuring compatibility with protected content and display control functions. A locking screw-on DC power adapter connector prevents accidental disconnection during operation, an important reliability feature in permanent AV installations.
