The R7 universal and learning remote control sends IR (infrared) commands to all home theater A/V equipment and can replace up to 7 different remote controls. With MacroPower, you can program the R7 to turn up to 7 components ON or OFF with the press of one button. The SimpleSound feature gives you total volume control over all the components in your system, even those that do not have their own built-in volume control, such as TiVo, DVD and VCR. The backlit buttons make it easy to see in dark rooms and an easy to follow DVD Guide that can help you setup your new R7 remote control is also included.
