5. Press the MLC button that will store the input selection IR codes. The button blinks
for 5 seconds, during which time it is able to learn codes. On the rear panel, the
first (bottom) IR learning LED starts flashing.) If a command is not entered within
5 seconds, the button and LED stop blinking, and you must press the button again to
put it in back in learning mode.
6. Within 5 seconds, press the display device remote control button from which the MLC
button will learn the first input selection command. If the command has been learned
successfully, the IR Learning LEDs on the rear panel blink in rapid progression from
the top LED to the bottom, then back to the top.
7. To program a second input selection command on the same button, press the button
again. The button and the second rear panel IR learning LED begin to blink. On the
remote control of your display device, press the next button whose function you want
the MLC button to learn.
8. Repeat the procedure described in steps 5 and 6 for additional commands you want
to add to the button you are programming. Each MLC button can be programmed
with up to four commands.
9. When finished programming the input selection button, set rear panel DIP switch 1
to Off (down). Verify that the button has been programmed correctly by pressing it
repeatedly to cycle through the inputs and observing the display.
Setting Up an MLC 52 VC Model with an Extron Amplifier
If you have an MLC 52 IR VC or an MLC 52 RS VC model, it can be connected to
an optional Extron amplifier, such as the MPA Power Amplifier Series, the MP Series
preamplifiers, or a PoleVault PVS switcher. The dedicated volume control knob on the VC
controllers controls the audio output of an Extron MPA 152 or MPA 401 power amplifier,
an MP Series Preamplifier, or a PoleVault PVS switcher, to which speakers for the system
are connected.
Wiring the VC Port
To set up this configuration, wire the volume control port to the amplifier as shown in the
following diagram. Set up the volume control, following the instructions in the amplifier
user guide.
NOTE: Use only Extron devices with the VC port.
