Pure Anthem Power

With 75W at 8 ohms x 12 channels, or up to 150W at 4 ohms, MDX-12 brings the power, you just need to add control. Forgoing the built-in Matrix switching of its advanced siblings the MDX-8 and MDX-16, MDX-12 instead features 6 dedicated analogue inputs assigned to each zone and 2 selectable global analogue inputs. Simply add the sources or matrix of your choice and MDX-12 is ready to deliver true Anthem power to your speakers. While designed for distributed audio solutions, MDX-12’s robust power output also makes it suitable for adding extra channels of power to any home theatre system.

Compact Size, Mighty Output

Occupying just a single 1U rack space, the MDX-12 boasts a highly efficient compact power supply, capable of delivering up to 1,000-Watts within its sleek chassis. Engineered by Anthem, this amplifier is designed to accommodate various custom speaker setups. For those seeking even greater power, the MDX-12 allows for channel bridging. When bridged, it delivers an impressive 280W at 8 ohms. Despite its potent performance, the MDX-12 remains cool under pressure thanks to its fan-cooled design, ensuring uninterrupted power delivery even in the most demanding scenarios.

Built-in Protections for Uncompromised Performance

MDX-12 utilises integrated amplifier chips with built-in safeguards, including protections against out-of-range current, temperature, and voltage conditions. Additionally, the amplifier features multiple thermal sensors strategically placed on the board to monitor temperature fluctuations. These protective measures ensure reliable performance and prevent damage to both the amplifier and connected speakers, making the MDX-12 suitable for distributed audio systems in diverse environments while maintaining optimal safety and quality standards.
