NuVo Technologies' Wireless Control Pad, which is now shipping, offers a new option for user control of NuVo's Grand Concerto and Essentia E6G multi-room audio systems, as well as the sources attached to them, such as satellite and terrestrial radio tuners, music servers, PCs, and iPods. The palm-held Wireless Control Pad features a 1.6-inch OLED screen, and is roughly five inches long, two inches wide and less than an inch thick, making it about the size of a smartphone. It is designed to receive metadata and operational feedback from the sources connected to the NuVo system.
