MLC 52 VC models with volume control faceplate
The two-gang sized MLC 52 IR VC and MLC 52 RS VC each have a projector
volume control knob in addition to the six control buttons. To use this knob, you
must connect the MLC 52 to an Extron MPA Series Mini Power Amplifier (sold
separately), to which you can also connect the projector (see the application
diagram below). The volume control knob adjusts the volume on the MPA, freeing
up the two MLC volume control buttons to be reconfigured and used for other
projector functions.
C
To use the MLC 52 in this type of application, the controller must be
configured with the Windows-based MLC 52 control software. Refer to
chapter 5, “Serial Communication,” in the MLC 52 User’s Manual,
provided on the CD included with your MLC 52, for details.
