    Introduction About the MediaLink Switchers The Extron MediaLink™ switchers (MLS 306, MLS 506, MLS 506MA [70V/100V], and MLS 506SA) are a family of rack-mountable, six-input (three video/S-video, three RGB/computer video) switchers with audio control. The MLS 506, MLS 506MA, and MLS 506SA can also accept component video input. Each can be used in stand- alone applications or can be connected to a MediaLink Controller (MLC 206) to add control functions for integration into small to mid-sized audio-visual systems.
