Introduction About this Manual This manual contains information about the Extron MLS 100 Series Switchers (MLS 100 A, MLS 103 V, MLS 103 SV, MLS 102 VGA) and on how to install, set up, and operate them. The terms “MLS 100 Series switcher”, “MLS”, and “switcher” are used interchangeably in this manual. About the MLS 100 Series Switchers The Extron MLS 100 Series Switchers are compact, quarter rack width switchers. The MLS 102 VGA, MLS 103 SV, and MLS 103 V have a 250 MHz (-3 dB) video bandwidth.
Installation UL/Safety Requirements The Underwriters Laboratories (UL) requirements listed below pertain to the safe installation and operation of the switcher. 1. This unit is not to be connected to a centralized DC power source or used beyond its rated voltage range. The Extron P/S 100 and other Extron power supplies may be used with the MLS.

Installation, cont’d Furniture or projector mounting Rear Panel Features and Cabling Furniture mount or projector mount the MLS using the optional mounting kit (part #70-212-01 for furniture; or 70-217-01 for projector) as follows: Turn off and disconnect power from all the equipment before you connect cables to the MLS. 1 1. Attach the mounting brackets to the MLS with the machine screws provided. 2. If feet were previously installed on the bottom of the MLS, remove them.
Installation, cont’d this port so the presenter’s comments can always be heard and are independent of the A/V source used for the presentation. Audio connections The stereo audio inputs 1–3 ( 7 and 8 on page 2-5 and below) correspond to video inputs 1, 2, and 3. All four audio inputs can be selected via the front panel buttons, RS-232 control (including MLC), or the MediaLink Control Software. An audio signal from one of these inputs is output only when the corresponding input is selected.
Installation, cont’d Control and power connections 11 MLC/RS-232 Power port (all models) — An Extron MediaLink Controller (MLC 206), a computer, or an RS-232 controller provides remote control of input switching and volume, and also provides a way to set the switcher’s audio input levels. To control and/or set up the MLS, connect a cable between this 5-pole, 3.5 mm captive screw connector and an optional MLC 206, computer, or a RS-232 controller.
Installation, cont’d HyperTerminal, a third party controller, or the MediaLink Control/Configuration Software). The gain and attenuation for the Aux/Mix input are adjustable only via the switcher’s front panel. (See page 3-3 for Aux/Mix details.) For dBV the reference is 1 volt. For dBu the reference is 0.775 volts. 5. In the control program, move the Audio Input Level slider to select the gain/attenuation for that input, as shown at left.

Operation audio does not change when you switch between the four selectable audio inputs. Front Panel Features and Operation MLS 100 Series Front Panel (all models) The last selected input (including audio/video breakaway selections) will be the active input when the MLS is powered on. Wait at least 10 seconds between making a change (input selection or audio adjustment) and disconnecting power from the MLS. The switcher needs several seconds to store the new settings in its memory.
Operation, cont’d Troubleshooting 1. The MLC to which the MLS 100 Series switcher is connected must have MLC firmware version 1.04 or higher. Use one of the following methods to find out the version levels of the MLC’s firmware and the control software. Connect the cables between the MLS and the A/V input devices. Connect the provided power supply and a host computer, third party control system, or MediaLink Controller to the MLS’s MLC/RS-232 Power port.
