Extron electronic MLC 62 IR D manual Volume adjustment

•IR and RS-232 ports — The MLC 64 and the MLC 62 RS models each have a dedicated serial port for communicating with most types of projectors or flat panel displays via unidirectional RS-232. They also have an IR/S port, which can be configured for IR or RS-232 control.

The MLC 62 IR D has only an IR port, which is used for IR communication only.

IR and RS-232 display drivers can be downloaded and used to configure the controller.

•Relays (RS models) — Two relay ports enable control of room devices such as lights, motorized screens, and projector lifts.

•Digital Input (RS models) — A Digital Input port enables monitoring of a switch or sensor to control devices.

•IR Learning — The MLC can be configured by IR learning, using the remote control of a switcher or display device to create an IR driver that enables the MLC to control the device.

•USB configuration port — The MLC can be configured via a USB mini B port, located on the front or side panel (depending on the model). This port can also temporarily provide power to the MLC during configuration.

•Volume adjustment:

•The MLC 62 models have individual Volume Up and Down buttons for audio level control, with five LEDs that indicate current audio settings.

•The MLC 64 has a volume control module with an analog potentiometer knob to control the audio level for an Extron amplifier that is enabled for remote volume control. The volume control module also contains a Mute button for muting and unmuting the audio (this button cannot be reprogrammed).

NOTE: Only Extron amplifiers can be controlled via the MLC 64 volume

control module.

•Macro capability — Each button can be configured to execute multiple actions through the serial or IR control ports. For example, a button can be configured so that a single press triggers commands to turn on a display, select the RGB input of the display, and trigger a relay.

•Toggling — Buttons can be placed in toggle mode, which adds flexibility by enabling two different sets of commands to be executed with alternating presses of the button.

•Built-in speaker — A speaker provides audible feedback to confirm user actions when buttons are pressed (except for the Mute button on the VCM module of the MLC 64 RS VC D).

•Inactivity timer for display shutoff — An adjustable timer controls automatic shutdown after a specified period of inactivity.

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

•Activity LED — A small LED at the top of the MLC front panel lights red, green, or amber to indicate button presses, data transfer, front panel lockout, and other actions.

•Section 508 Compliant — The MLC meets or exceeds accessibility standards for Electronic Information Technology. For more information about the Extron Commitment to Accessibility, see the Extron Accessibility web page at www.extron.com/company/article.aspx?id=accessibility.
