The Extron MLS 406
Model Version Description Part #
MLS 406 Variable Preamp Audio Output 60-560-01

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.

The MLS 406 switcher provides three configurable 15-pin HD inputs to support high resolution RGBHV, S-video, or composite video sources with 15-pin HD local monitor loop-through. Three additional inputs are configurable to accept S-video or composite video signals, and all inputs support stereo audio. A line level mono audio auxiliary/mix input is available for consumer and professional audio sources such as a wireless microphone receiver for mixing with the selected input. The switcher also features audio input gain and attenuation for each input, plus loudness control and master volume control through the front panel or via RS-232.

The MLS 406 includes two preamp balanced or unbalanced audio outputs, one fixed and one variable. All outputs can be configured via RS-232 for mono or stereo audio output.
