The ADJ 12PX HEX is a DMX-intelligent LED par fixture designed for professional lighting applications. Before operation, ensure the unit is inspected for shipping damage. Warning: This fixture emits high-intensity ultraviolet (UV) light. Avoid direct eye and skin exposure at distances shorter than 11 feet (3.3m). Do not operate the unit if the cover is damaged or missing. Always disconnect from main power before making any connections.
Installation and Mounting
The unit must be installed by a professional in a location out of reach of the public. Always ensure the mounting structure is secure and capable of supporting 10 times the weight of the unit. Use a safety cable capable of holding 12 times the unit's weight. Ensure there is at least 6 inches (15cm) of space between the device and any wall for proper ventilation.
DMX Setup and Addressing
The fixture supports DMX-512 protocol with 3-pin and 5-pin XLR connections. When linking multiple units, use standard 110-120 Ohm shielded DMX cable. The DMX address is set via the digital control display on the back panel. For longer cable runs, use a DMX terminator (120 Ohm resistor) on the last unit in the chain to prevent signal errors.
Operating Modes
The 12PX HEX offers five operating modes: Sound Active, Program, RGBWA + UV Dimmer, Static Color, and DMX Control. The fixture supports four DMX channel modes: 6, 7, 8, and 12 channels. You can also configure units in a Primary-Secondary setup, where one unit acts as the controller for others.
System Menu Navigation
The control panel locks automatically after 30 seconds of inactivity. To unlock, press and hold the Mode button for 3 seconds. Use the Mode, Enter, Up, and Down buttons to navigate the menu to set DMX addresses, select channel modes, adjust dimmer curves, and configure LED refresh rates.
Maintenance and Troubleshooting
Periodically clean the internal and external optical lenses to optimize light output, especially if the fixture is used in environments with smoke, fog, or dust. Use a soft cloth and glass cleaner. If the unit does not respond to DMX, check cable connections and wiring. If it does not respond to sound, ensure Sound Active mode is enabled and the sound source is not too quiet or high-pitched.
