This product has been retired.

The Extron MLS 506SA is a simple-to-use, six input, multi-format switcher that provides composite video, S-video, component video, and RGB 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 features an integrated audio amplifier with 50 watts, 2 x 25 watts rms, into 4 or 8 ohm speaker loads for use of program speakers, and includes two preamp audio outputs. For enhanced operation, ease of room control, and simplified system integration, the MLS 506SA can be controlled with a TouchLink^® Control System or MediaLink^® Controller.

The MLS 506SA switcher provides three configurable 15-pin HD inputs to support high resolution RGBHV, S-video, component video, or composite video sources with 15-pin HD local monitor loop-through. Three additional inputs are configurable to accept S-video, component video, or composite video signals, and all inputs support stereo audio. The switcher also features an auxiliary line level audio input for mixing with the switched inputs and an effects, loop in/out feature for external signal processing. It can then output the externally processed audio as an amplified signal.

In addition to the integrated amplifier, the MLS 506SA 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.

Features

Inputs: Video on female BNC connectors; audio on captive screw connectors

Outputs: Video on female BNC connectors; audio on captive screw connectors

Controllable via TouchLink^® Control System, MediaLink^® Controller, front panel buttons, or RS-232 — The switchers can be controlled using the front panel backlit buttons or RS-232. An optional TouchLink Touchpanel Control System or MediaLink Controller may be connected to the RS-232 port to provide a simple and intuitive user interface for the MLS Switchers, and the entire room.

Audio input gain and attenuation — Gain or attenuation can be adjusted for each input to eliminate noticeable differences when switching between sources.

Fixed and variable preamp line level audio outputs — Can be set for mono or stereo via RS-232.

Integrated stereo audio amplifier provides 50 watts, 2 x 25 watts rms, into 4 ohm or 8 ohm speakers — Outputs amplified stereo audio on insulated screw terminals.

Volume, bass, and treble adjustments — Audio input levels may be adjusted from -78 dB through +24 dB of gain and attenuation.

Triple-Action Switching™ for RGB delay — Blanks the screen during switching of RGB signals to eliminate visible switching transitions.

9-pin contact closure for remote control — Contact closure can be used for external control of source switching.

Front panel security lockout — Allows security lockout of front panel buttons except for input selection and volume adjustment.

Rack-mountable, 2U, full rack width metal enclosure with included brackets

Internal Extron Everlast™ power supply — Provides worldwide power compatibility, with high‑demonstrated reliability and low power consumption for reduced operating cost

Extron Everlast Power Supply is covered by a 7‑year parts and labor warranty
