The ADJ UB 12H is a DMX-intelligent, LED bar fixture designed for stage or wall washing. It features 12x 6W HEX LEDs (RGBAW+UV) and offers multiple operating modes, including stand-alone and primary/secondary configurations.

Safety Precautions
Warning: This fixture emits high-intensity ultraviolet (UV) light. Avoid direct eye and skin exposure at distances shorter than 11 feet (3.3m). Wear proper eye and skin protection. Do not look directly into the light source.

Electrical Safety: Do not expose the unit to rain or moisture. Ensure the power source voltage matches the unit's requirements. Do not remove the cover or attempt repairs yourself, as there are no user-serviceable parts inside.
Installation
The unit must be installed by a professional. Use a mounting clamp (not provided) to affix the unit to the provided bracket. Ensure the mounting structure can support at least 10 times the unit's weight. Always use a safety cable capable of holding 12 times the unit's weight. Maintain at least 6 inches (15cm) of clearance for ventilation.
Operating Modes
The UB 12H offers six operating modes:
- Static Color Mode: Choose from 63 color macros.
- RGBWA+UV Dimmer Mode: Adjust the intensity of individual colors to create custom mixes.
- Built-In Program Mode: Select from 22 built-in programs with adjustable speed and fade.
- Auto Run: Automatic program execution with adjustable fade and strobe.
- Sound Active Mode: Reacts to sound using the built-in microphone.
- DMX Control Mode: Control fixture traits via a standard DMX 512 controller.
DMX Setup
The fixture supports 6, 10, 12, and 36-channel DMX modes. Use a standard 110-120 Ohm shielded DMX cable for data input and output. For long cable runs, use a terminator (120 Ohm resistor) on the last unit in the chain to prevent signal errors.

Magnetic Quick Align
This feature allows multiple fixtures to be connected securely end-to-end on flat surfaces like floors or stages. To use, unscrew the thumb screws on both ends, remove the brackets, and position the fixtures together.

Maintenance
Fuse Replacement: Disconnect the power cord, use a flat-head screwdriver to remove the fuse holder, and replace the fuse with one of the same rating.
Cleaning: Periodically wipe down the outside casing and external optics with a soft cloth and normal glass cleaner to remove dust and fog residue. Ensure all parts are dry before reconnecting power.
