Operating Instructions

Using MasterPlus+ Software (Recommended for Gen2 ARGB)

• Launch the MasterPlus+ software after installation.
• The software will detect the connected LED Controller A1.
• Navigate through the software interface to access various lighting modes, color palettes, and effects.
• For Gen2 ARGB devices, you can individually control each LED's color and brightness, offering granular customization.
• Save your preferred lighting profiles for quick access.

Basic Button Operation (for Standard ARGB)

If you are using standard ARGB devices or prefer not to use the software, the controller may offer basic lighting control via a physical button (if present on the device itself or connected via a case button). Refer to your PC case or connected ARGB device manual for specific button functionalities. Typically, a button allows cycling through pre-set lighting modes and colors.
