Introduction
About the MediaLink Switchers
The Extron MediaLink™ switchers (MLS 306, MLS 506, MLS 506MA [70V/100V],
and MLS 506SA) are a family of rack-mountable, six-input (three video/S-video,
three RGB/computer video) switchers with audio control. The MLS 506, MLS 506MA,
and MLS 506SA can also accept component video input. Each can be used in stand-
alone applications or can be connected to a MediaLink Controller (MLC 206) to add
control functions for integration into small to mid-sized audio-visual systems.
“MLS”, “MediaLink Switcher”, and “switcher” will be used interchangeably in this
manual to refer to all models of MediaLink switchers.
Features and Options
Standard features
Flexible control options — The MediaLink switchers can be controlled via RS-232
connection to a third party control system or an Extron MediaLink Controller.
They can also be controlled by contact closure devices.
Audio volume control — All MLS models offer audio preamp volume adjustment
(attenuation) via a front panel rotary knob.
Bass and treble control — The bass and treble levels can be set separately for each
audio input.
Audio amplification (MLS 506MA and MLS 506SA only) — The MLS 506MA and
MLS 506SA offer amplified outputs and an effects loop that allows you to add
a device such as an equalizer into the system ahead of the amplified audio
output.
Customizable input labeling — Customized input selection button labels can be
created by using a labeling machine such as a Brother P-touch labeler, or you
can use Extron software to create and print labels.
Executive mode — You can set the switcher to executive mode to prevent changes
to settings from being made from the front panel controls. When executive
mode is active, only input selection can be performed from the front panel.
Triple-Action Switching
™
— When the MLS switches between RGB inputs, the
screen goes black briefly (you set the delay time) while the display locks on to
the new input’s sync signal, then the RGB picture is displayed without glitches.
