Introduction
MLC 52
Extron MLC 52 RS EU and MLC 52 RS VC EU
MediaLink Controllers are economical control
panels ideally suited for conference room
or classroom A/V systems. Each model fits
in a standard two-gang European junction
box and offers IR control and unidirectional
RS-232 control. The MLC 52 RS VC EU adds
an integrated volume control knob for use with
any Extron power amplifier or preamplifier with
a remote volume control port. By providing
easy input selection, power, and volume
control, these controllers make classroom A/V
operations simple. Both models are available in
a RAL9010 white or brushed aluminum finish
to complement a wide range of environments.
Consistent A/V Control in Every Room
Each MLC 52 controller acts as an extended
remote control panel, providing user-friendly
control for a display’s power, volume, and
input selection. Because the MLC 52 offers a
central point of control for a display device’s
key functions, it eliminates the need for the
display’s handheld IR remote control, making
operations much more efficient. With the
MLC 52, there are no misplaced remotes to
search for, no confusing menus to navigate
through, and no dead batteries to replace.
No matter what brand of display is installed in
each presentation venue, MLC 52 MediaLink
Controllers always provide a consistent control
method from room to room. Presenters with
little or no training can walk into any MediaLink
equipped classroom and operate the A/V
system with ease.
Configurable Buttons for Flexible
Control Options
The MLC 52 MediaLink Controllers are easy
to configure and no programming is required
to make them work. Each MLC 52 features six
buttons that can be configured to control almost
any function of the projector, such as selecting
an input, controlling the volume, muting the
picture, or switching it on and off. Using the
intuitive setup software provided, these buttons
can be configured to send out any IR or RS-232
command supported by the projector, making
it easy to customize the controller to meet the
needs of single-display A/V systems.
Each button can store up to four separate
commands, providing additional flexibility to
meet the specific control requirements for most
display devices. When a button is configured
for Macro mode, all of the stored commands
associated with that button can be sent with
the press of a single button. In Toggle mode,
the button steps through a series of two, three,
or four commands, issuing a single command
with each press of the button.
Free Projector Drivers
Extron creates and administers a wide selection
of commonly used projector control drivers.
These IR and serial RS-232 drivers allow
MediaLink Controllers to communicate with
a display device. They enable control of basic
projector functions such as power, input
selection, and volume adjustment. Go to
the Extron Web site at www.extron.com to
download drivers for the latest and most popular
projectors.
Three Easy Ways to Configure
The MLC 52 enables integrators to choose
any of three methods when configuring the
controllers. When used with the supplied
Windows®-based configuration software,
installation files can be saved and used to
duplicate additional MLC 52 controllers. The
files can also be archived for later use.
Simple configuration wizard• - Experience fast
and simple setup within minutes using the front
panel configuration port, supplied software, and
the PC’s RS-232 port. Quickly allocate a function
to a button just by dragging the command to the
desired button.
IR learning• - Set up the MLC 52 directly by
beaming commands from the IR remote to the
MLC 52, without the need for software and a PC.
IR beaming• - Setting up multiple controllers
with the same configuration is made easy with IR
beaming. Simply beam the complete configuration
from one MLC 52 controller to another controller,
without using any cable or software.
Convenient EU Size
The MLC 52 RS EU Series controllers were
designed to fit the standard two-gang
(MLC 52 RS EU) or 2-gang (MLC 52 RS VC EU)
European junction box.
