LD Systems MON 12 A G3 Description
The LD Systems MON 12 A G3 brings premium monitor technology to portable and permanent setups alike. Its coaxial 12" design with a 1.75" titanium-diaphragm HF driver produces consistent phase alignment and wide coverage through a 50° x 90° constant directivity horn. This results in a true point source ideal for accurate monitoring at close range or controlled FOH deployment.
At the heart of the MON 12 A G3 is a 300W RMS (1200W peak) Class-D amplifier paired with LD’s proprietary DynX DSP. This second-generation processing ensures distortion-free performance even at maximum volume, while built-in tools like a 3-band EQ, tunable notch filter, delay line, and four sound presets provide flexible sound shaping.
Connectivity is intuitive and professional, with PowerCON-compatible in/out for power daisy-chaining and dual XLR outs for signal chaining. A 35 mm pole mount enables FOH use, and recessed controls help avoid accidental adjustments during performances.
Built to endure the demands of touring, the cabinet is made of 15 mm birch plywood with a rugged polyurea coating, steel grille, recessed connectors, and die-cast aluminum handles. Whether on stage or supporting events, the MON 12 A G3 combines robust design with modern acoustic performance.
