Once again Ethereal Home Theater answer's the need of the custom installer. While recently there has been a rush to use active cables for longer HDMI runs some dealers still want to play it safe with a passive cable and an active Black Box Repeater (like the HDM-SR1A or HDM-SR1-HS). For years the Ethereal HDM-SR20 and HDM-SR30 were the preferred solution for this type of install. Unfortunately they were dropped from our lineup. Well, they are back! And even better than before, updating and upgrading our long distance passive HDMI cables to our MHX series product and for the first time providing a 100' High Speed 3/D or 4K option with the HDM-SR30HS.
