User Guide Owner's manual

• Inactivity timer for display shutoff — Adjustable timer control provides automatic
shutdown of the display device to conserve energy, prevent plasma burn-in, and
extend projector lamp life.
• Front panel security lockout — Front panel lockout (executive mode) can be
implemented where the MLC 52 is installed in an unsecured environment and
universal access is not desirable.
• Flexible mounting options — With a standard electrical box or one of the included
mounting brackets (“mud rings”), the MLC 52 can be mounted in a variety of
locations, including walls and lecterns.
• Volume control (VC) faceplates — The two-gang sized VC models each have
an integrated volume control knob in addition to the six control buttons. To use this
knob, connect the MLC 52 to a power amplifier (purchased separately), such as the
Extron MPA Series Mini Power Amplifier that is also connected to the projector or
display (see the application diagrams on page 4). The volume control knob adjusts
the volume on the amplifier.
This option frees the two volume control buttons on the MLC to be used or
reconfigured for other display device functions. On these models, the two buttons
normally used for volume control on the standard MLC 52 models can be
programmed to control additional outputs or other projector or display functions.
• Section 508 Compliant — The MLC 52 meets or exceeds accessibility
standards for Electronic Information Technology. For more information about the
Extron Commitment to Accessibility, see the Accessibility at Extron web page at
www.extron.com/company/article.aspx?id=accessibility.
• Power supply — A 12 V, 1 A, external universal ENERGY STAR
®
qualified power
supply, part number 70-775-01, is included and provides worldwide compatibility, low
power consumption, and reduced operating costs.
NOTE: The Extron PS 124 and other Extron power supplies can also be used
with the MLC 52.
Options and Accessories
• MPA Series Mini Power Amplifier — Connect an MPA 152 (part number
60-844-01) to the volume control port of the MLC 52 VC models, and to your
projector or display and speakers. This enables you to use the MLC volume knob to
control the volume of the speakers via the MPA.
• Remote control — The optional IRL 20 signal repeater provides infrared remote
control of the MLC unit from up to 30 feet (9.1 m) away. The signal repeater works
with any Extron hand-held IR remote control.
MLC 52 Configuration Software
The included MLC 52/DVCM 50 Configuration Program is used to configure the MLC
buttons and ports via an RS-232 connection. This software, provided on a DVD that is
delivered with the product, enables you to set functions for the front panel buttons and
to configure the MLC ports in order to control devices via the MLC. The software works
in combination with the IR or RS-232 drivers, also provided with the MLC on DVD or at
www.extron.com (see Installing the Software from the DVD on page 48 to access
this program).
