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. “MLS 100 Series switcher”, “MLS”, and “switcher” will be 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 (-3dB) 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.

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 Audio connections 9 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. Using the MediaLink Control Software you can separately adjust the level of each of these audio inputs.
Installation, cont’d Control and power connections 11 MLC/RS-232 Power port (all models) — An Extron MediaLink Controller (MLC 206), a computer, or a third party 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 third party RS-232 controller.
Installation, cont’d Gain and attenuation are adjustable (from -18dB to +24dB) for each input (1 through 4) via RS-232 control only (using HyperTerminal, a third party controller, or the MediaLink Control 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.) output, it causes the audio signal to be attenuated by 6dB (gain = -6dB). For dBV the reference is 1 volt. For dBu the reference is 0.775 volts. 5.
