The Extron MLC 52 RS VC Basic MediaLink^® Controller is a two-gang, economical control panel with an integrated volume control knob for any classroom environment. With IR and unidirectional RS-232 display control, the MLC 52 RS VC provides easy input selection, power, and volume control, making classroom AV operations simple.

Simple, Consistent Control in Every Room

The MLC 52 RS VC acts as an extended remote control panel, providing user-friendly control for a display's power, volume, and input selection. Because the MLC 52 RS VC offers a central point of control for a display device's key functions, it eliminates the need for the display's IR remote control, making operations much more efficient. With the MLC 52 RS VC, there are no misplaced remotes to search for, no confusing menus to navigate, and no dead batteries. No matter what brand of display is installed in each presentation venue, the MLC 52 RS VC MediaLink Controller always provides a consistent control method from room to room. Presenters with little or no training can walk into any MediaLink equipped classroom and operate the AV system with minimal effort.

Integrated Volume Control

The Extron MLC 52 RS VC features an integrated volume control knob for remote volume control of any Extron power amplifier or preamplifier with a remote control volume port. Captive screw connectors on the back panel provide for quick and easy connectivity to the amplifier's remote volume control port. The rotary volume control knob enables easier adjustment and ensures precise volume levels.

Configurable Buttons for Flexible Control Options

No programming knowledge is necessary to install MLC 52 MediaLink Controllers. Three of the four lower buttons on the MLC 52 RS VC ship pre-labeled with the following labels: VCR, DVD, and PC. The fourth button is not pre-labeled. Using the intuitive setup software provided, these buttons can be configured to send out any IR or RS-232 command supported by the display, making it easy to customize the controller to meet the needs of most single-display AV systems. For example, three of the four buttons could be configured for input selection, with the fourth button dedicated to video mute or auto image. 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 are sent with a single button press. 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.

Three Easy Ways to Configure

The MLC 52 RS VC 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 models. The files can also be archived for later use.

IR learning - Allows the MLC 52 RS VC to be set up directly from the IR remote without the need for software and a PC.
IR beaming - Quickly and easily duplicates complete configuration from one MLC 52 model to another without cables or software.
Extron's easy-to-use configuration software - Provides fast and simple setup via RS-232 when combined with one of many IR drivers available on the Extron Web site.

Features

Unidirectional RS-232 and IR port for universal display control — The MLC 52 RS VC has dedicated ports for communicating with virtually any projector or flat panel display via IR and/or unidirectional RS-232 wired serial control. Display control drivers can be downloaded from the Extron Web site and used to configure the controller.

Discrete ON and OFF display power controls — Simplify system operations and eliminate the need for a handheld IR display remote.

Integrated volume control knob - Provides remote volume control of any Extron power amplifier or preamplifier with a remote volume control port

Configurable buttons — Can be set up to control display power, volume, input selection, or any other IR/RS-232 command supported by the display.

Macro and Toggle modes for each button — Each button can be set to send out multiple IR commands. A button configured for Macro mode can send several commands in sequence. A button configured for Toggle mode will sequence between up to four different commands, sending out a different command each time the button is pressed.

Backlit buttons can be custom labeled for easy identification — Buttons illuminate for ease of use in low-light environments.

Removable button caps — Make it easy to label each button to clearly indicate its function; labels can be quickly changed and don't require programming or engraving.

Front panel configuration port — Advanced configuration, driver downloads, and firmware updates can be performed via the front panel configuration port without removing the controller. The optional Extron CFG Cable, part # 70-335-01, connects the MLC 52 RS VC to the PC's RS-232 port.

Configuration options: IR learning, IR beaming, and Extron's easy-to-use configuration software

Inactivity timer for display shutoff — Adjustable timer control provides automatic shutdown to preserve energy, prevent plasma burn-in, or extend projector lamp life.

Front panel security lockout — If the MLC 52 RS VC is installed in an unsecured environment where easy access is not desirable, a security lockout feature may be implemented to lock out all front panel controls.

Section 508 Compliant — Meets or exceeds accessibility standards for Electronic Information Technology. For more information about Extron's Commitment to Accessibility please see our Accessibility Page.

Includes black and white two-gang, high-impact plastic mounting faceplates — The MLC 52 RS VC comes with two two-gang, high-impact plastic mounting faceplates durable enough for demanding environments.

Includes black and white MR 200 two-gang mud rings

Flexible mounting options — Utilizing a standard two-gang electrical box or included black and white mud rings, the MLC 52 RS VC can be installed virtually anywhere, including walls, lecterns, or tables.

Highly reliable, energy-efficient external universal power supply included, replacement part #70-775-01 — Provides worldwide power compatibility, with high demonstrated reliability and low power consumption for reduced operating costs.

Note: Part # 60-745-14 has been retired. A brushed aluminum mounting option is available, part # 70-538-04.
