5.2 Power Connection
Connect the provided power cable to the Power IN socket on the rear panel of the fixture and then to a suitable grounded power outlet (AC 100-240V, 50/60Hz).
5.3 DMX Connection (Optional)
For DMX control, connect a DMX controller to the DMX IN port of the first fixture using a 3-pin XLR cable. To daisy-chain multiple fixtures, connect the DMX OUT of the first fixture to the DMX IN of the next, and so on. Terminate the last fixture in the chain with a DMX terminator (not included) for optimal signal integrity.
6. Operating Instructions
The ENDYSHOW LED Blinder Stage Light offers several operating modes, selectable via the LED display and control buttons on the rear panel.
6.1 Control Panel Navigation
- MENU: Press to cycle through main menu options.
- UP/DOWN: Use to navigate within a menu or adjust parameter values.
- ENTER: Confirm selection or save changes.
6.2 Operating Modes
The fixture supports the following modes:
- DMX Mode:
Allows external control via a DMX controller. Set the DMX address using the control panel. The fixture uses a 6-channel DMX profile. Refer to the DMX Channel Chart in Section 7 for details.
- Master/Slave Mode:
Connect multiple fixtures via DMX cables. Set one fixture as the "Master" and others as "Slave." The slave units will mirror the master's operation. The light automatically recognizes the master/slave function.
- Sound Activation Mode:
The fixture reacts to ambient sound, creating dynamic light patterns. Adjust sensitivity via the menu if available.
- Standalone Mode (Auto Programs):
The fixture runs pre-programmed light sequences. Options may include static color, color changing (fade, jump), strobe, and blinder effects. Use the control panel to select desired programs and adjust parameters like speed or brightness.

6.3 Color Temperature Adjustment
The 2-in-1 COB LEDs allow for cool white, warm white, or a mixed neutral white output. In DMX mode, specific channels control the intensity of each color component. In standalone modes, pre-programmed effects or manual settings may allow for color temperature selection.
