This makes HDMI signals more prone to radio interference. When you look at an HDMI coupler like this Amazon Basics model (on Amazon), you can see how the body is a plastic piece that doesn’t have shielding like the cable does. This effect is reduced when there is a break in the shielding. To prevent radio interference, HDMI cables are shielded with woven alloys and rubber. Unfortunately, we live in a world of radio interference and mechanical malfunction. Why an HDMI Coupler is Not the Best Option In theory, the contact between the pins of the male and female connections would be functionally the same as a single wire. In an ideal world, this would be as good as having a single, continuous cable. This facilitates the connection between the male plugs of two HDMI cables. An HDMI coupler simply connects the pins between two female jacks. HDMI cables use 19 wire pairs that terminate in as many pins at the plug. This is because having a female jack on devices protects them in the event that they are dropped or hit, and because most HDMI cables are male-to-male. As you have likely noticed, HDMI cables predominantly come male-to-male. What is an HDMI Coupler or Barrel?Īn HDMI coupler is a small part that connects two HDMI signals through two opposite-facing female jacks. But for the most part, HDMI couplers should be your last resort in extending your HDMI cable. There are a number of solutions for extending your HDMI cable, and all have various advantages and disadvantages compared to an HDMI coupler. The best solution is an HDMI Balun kit, which uses Ethernet to transmit the signal between your devices instead of an HDMI cable. And through use, the HDMI connector will loosen and may break when cables are tugged. Simple, but is it the best solution?Īn HDMI coupler will degrade your signal. Simply get another HDMI cable, connect them with the coupler, and you’re done. Sometimes called “HDMI barrels,” HDMI couplers seem like they are a straightforward solution to extending HDMI cable. If you’re extending an HDMI cable, chances are you have come across HDMI couplers.
