The manual mentions Niles Audio and Xantech as manufacturers of devices that will work with the 990 remote input jacks. Can anyone recommend or refer me to specific models of these or other manufacturers known to work with the 990? The cabinet that will house the 990 (when it arrives) may require that it be concealed so I'm hoping that a remote sensor will allow remote control of the 990 sitting behind a panel. Would I need only a sensor connected directly the IN1 or IN2 jacks? Or would it require some "kit" with emitters as well? Any information, or even first-hand experience with this would be greatly appreciated.
