HDMI Power Adapter with 50cm USB Power CableThis certified HDMI male - female adapter is used to extend HDMI signal connections over longer distances. Using the integrated 50cm USB cable with USB-A plug, the adapter can be supplied with power. The incoming HDMI signal is processed and can be extended over longer distances than with a passive HDMI adapter. Thanks to this signal processing as well as the 24ct. gold-plated plugs, a lossless and error-free signal transmission over long distances is possible without any problems.BENCHMARK FOR PROFESSIONAL INSTALLATIONSHigh-quality materials, custom-fit plugs and couplings, gold-plated pins as well as waiving unnecessary parts, PureInstall products are a good investment for any field of use. The Latest GenerationOur PureInstall HDMI adapters comply with the latest HDMI standard - HDMI High Speed with Ethernet. They support resolutions up to 4K (4096x2160) with up to 60Hz and are backwards compatible with all former HDMI versions. Power for Greater DistancesDue to an additional external power supply option via USB with a USB-A plug and 50cm cable length, the signal of the HDMI cable can be amped and extended. Custom-fit, Durable and Without LossesThe precise manufactured and custom-fit 24-carat gold-plated pins guarantee a perfect transmission and permanently lasting functionality. Secure-Lock-System™Conventional HDMI plugs easily lose grip in the socket. The solution: PureLink® High Speed HDMI adapters with Secure-Lock-System™. The SLS™ technology was developed by PureLink especially for a more secure use of HDMI connections. This plug design is one of a kind on the current market and enhances the stability of the connection even with high traction rates, securing the connection permanently. HDMI Ethernet Channel and Audio Return ChannelThe Ethernet channel (HEAC) within the HDMI cable is a new feature of the HDMI 1.4 standard. With this channel within the cable, you can integrate IP-based entertainment devices such as your TV, set-top-boxes or gaming consoles into your home network, including internet or IP-based services without additional cables. The audio return channel (ARC) eliminates (like the Ethernet channel does), an additional cable within the home cinema system. The ARC sends the digital audio signal - via the HDMI cable - back to your AV-receiver. Therefore, there is no more need for a separate connection with a Toslink cable. For Professional Purposes and InstallationsAll PureInstall adapters are manufactured in only the most modern production facilities and are tested a 100% before shipping. During the manufacturing process, the adapters undergo over ten quality tests, making them the most reliable choice on the market.
