The Extron MLS 406 is a simple-to-use, six input, multi-format switcher that provides computer-video, S-video, and composite video switching, along with stereo audio input switching. An additional input accepts balanced/unbalanced mono line level audio signals for mixing with any of the four switchable inputs. The switcher includes a fixed and variable preamp output that can be configured for mono or stereo output to suit the needs of the installation. For enhanced operation, ease of room control, and simplified system integration, the MLS 406 can be controlled with a TouchLink^® Control System or MediaLink^® Controller.
