Extron electronics MediaLink MLC Plus 50 User Manual

MLC Plus 50/100/200 Series • Operation 31
Buttons
C
Buttons — All buttons are backlit so they are visible in low light conditions. By default,
the active (selected) buttons light brighter than inactive buttons. The light intensity and
blink rate can be set during configuration. Each button can be configured with a variety
of commands and functions, as desired.
Volume Controls and LEDs
E
Volume control knob and LEDs — You must configure the knob. It can be
used for any function and behavior and to control any device. However, the most
common configuration is to rotate the Volume knob clockwise to increase the audio
volume, counterclockwise to decrease volume. The LEDs (on all models except the
MLCPlus50) to the left of the knob can be set to light in patterns such as upward
or downward sweeps to indicate increases or decreases for increment/decrement
adjustments, or to indicate a volume level range for range-based adjustments (see
“Volume control options” below for additional details).
For all models, when audio mute is active, mute would typically
be indicated by a slowly blinking LED (shown in the diagram at
right), no matter which port is used for audio control or what
mode (range-based) is being used. When the audio is unmuted,
the volume returns to the previously used level.
Volume control options
Global Configurator software lets you select whether the MLCPlus knob controls the audio
levels of the projector (or another AV device) or of an optional Extron amplifier. Once
configured, the Volume knob can:
• Work in conjunction with the MLCPlus rear panel volume control port to control the
volume of an Extron audio power amplifier. See the information on the volume control
port on page21 for connector pinouts, wiring, and useful installation notes.
• Control audio volume via a projector or other device using serial or IR control
commands together with a COM or IR port on the MLCPlus.
If the knob controls the audio levels of the projector, you can specify incremental
adjustments or range-based adjustments (via device driver only). See the GlobalConfigurator
Plus and Global Configurator Professional Help File for details on these types of volume
adjustments and on how to configure the Volume LEDs for the desired lighting behavior.
Range-based volume adjustment
If the MLCPlus is configured for use with some projectors, the most common way to
configure the LEDs on the MLCPlus is to indicate volume ranges (with steadily lit LEDs),
as shown in the following diagram.
