Leviton MC 7500 Series Memory Lighting Controllers
22. AUDIO Button:
This button toggles the audio mode ON and OFF. When the LED above the button is
lit, the audio mode is active.
23. Bump Master Slider:
This slider controls the intensity of the channel bump buttons always, and the submaster
bump buttons when they are in the normal bump mode only.
24. MODE Button:
This button controls the operating mode of the Channel Bump buttons. Normally
the bump buttons cause the respective channel to go to the intensity of the Bump
Master Slider while pressed and back to normal when released. In the Toggle mode,
the bump buttons toggle ON and OFF. In the Solo mode, the bump buttons will kill all
other console output except for the bump buttons that are pressed. The LEDs above
the button indicate the channel bump mode. The normal mode is indicated when both
LEDs are out.
25. BLACKOUT Button:
This button is used to kill all output to stage except from the Bump buttons. The controller
is in Blackout whenever the Blackout LED is lit red. Blackout is OFF whenever the
Blackout LED is green.
26. Grand Master (GM) Slider:
This slide control is used to proportionally vary the overall console intensities to stage
except those from the Bump buttons. Whenever the Grand Master is not at full, the
Blackout LED will flash.
27. Worklight Connector:
This connector supplies 12 VAC at 1A to operate standard gooseneck work lights. Since
the light is powered by the same supply that provides power to the isolated DMX512
circuit,
the metal portion of the gooseneck and lamp should not be allowed to
touch the chassis ground
or other metal objects to prevent DMX512 interference.
The lamp power is protected by a special internal fuse that will interrupt power to the
lamp while retaining isolated DMX512 power in case of a lamp short.
28. LCD Function Buttons:
These four buttons are located directly under the LCD display. The functions of these
buttons change with the LCD display. The current function of each button is displayed
directly above the button on the display.
29. HELP Button:
This button activates the help system. To display help on any other button, press the
help button, followed by pressing any other button desired. The LCD will display a
short message describing the function. To exit help, press the HELP button or any
other button again.
30. CHANGE Button:
This button is used to cause the encoder wheel to effect a change on most parameters
displayed in the center of the LCD. To change a parameter, hold the CHANGE button
down while rotating the encoder wheel. Note that changing the fade rate does not
require that the CHANGE button be held down whenever fade rate is displayed.
31. MAIN MENU Button:
This button forces any changes to LCD parameter to be save and returns the LCD
display to the main menu display (fade rate is displayed).
32. CANCEL Button:
This button cancels selected functions and parameter changes in some cases.
33. Encoder Wheel:
This rotary knob is used for changing fade rate and other data entry. Rotating the
wheel slowly cause fine, incremental changes. While rotating quickly cause the rate
of change to be significantly increased for coarse changes.
