5. Setup
5.1 Installation
The stage light can be installed in various ways:
- Surface Placement: Place the light on a stable, flat surface such as a floor or stage.
- Mounting: Use the provided mounting bracket and screws to hang the light from a truss, ceiling, or stand. Ensure the mounting surface can support the weight of the fixture and that it is securely fastened. The angle of the stand can be adjusted as needed.
5.2 Power Connection
Connect the provided power cord to the power input on the rear of the unit and then to a suitable AC 100-240V/50-60Hz power outlet.
5.3 DMX Connection (Optional)
For DMX control, connect a DMX cable from your DMX controller's output to the DMX INPUT of the first light. For multiple lights, daisy-chain them by connecting the DMX OUTPUT of the first light to the DMX INPUT of the next, and so on.

6. Operating Instructions
6.1 Control Panel Operation
The LED display and buttons on the front panel allow for direct control and setting adjustments:
- MENU: Press to cycle through different menu options (e.g., DMX address, control modes).
- UP/DOWN: Use to navigate through menu options or adjust parameter values.
- ENTER: Confirm selection or save changes.
- MIC: Integrated microphone for sound-activated mode.
6.2 Control Modes
The light offers several operational modes:
- DMX512 Mode: For professional control using a DMX console. Set the DMX address via the control panel. The light supports 9 or 11 DMX channels. It is recommended to use a physical DMX console for operation rather than internet-downloaded DMX systems.
- Master/Slave Mode: Connect multiple units via DMX cables. Set one unit as 'Master' and others as 'Slave' to synchronize their movements and effects.
- Stand-alone Strobe Mode: Activates a continuous strobe effect without external control.
- Automatic Mode: The light runs through pre-programmed sequences and patterns automatically.
- Sound Activated Mode: The light reacts to ambient sound or music detected by its built-in microphone, changing patterns and movements in sync with the beat.
6.3 Remote Control Operation
The wireless remote control provides convenient access to key functions from a distance of 10-30 meters. Note that the remote control is primarily for self-propelled, voice-activated, positioning, and fixing figure modes, and cannot fully substitute a DMX console.
