The iPort IW-21's RJ-45 modular connections delivers unbalanced audio and video up to 30 feet, for use with local-zone audio/video systems. IR capability via the illuminated LED on the faceplate allows control of the volume and essential iPod menu and playback functions by an optional iPort EX-1 remote. The included wall plates provide stereo RCA audio and a composite video connection for output of iPod video content. The IW-21's front panel features a lighted status indicator and is designed to accept all Apple dock connector iPod models. It includes a back support, a rubberized adjustment disc that compensates for the varying thicknesses of different iPod models.
