Anthem MDX-8 Multizone Amplifier

The Anthem MDX Series is a statement in relentless performance and engineering, designed to bring Anthem’s renowned sound quality to every room in your home or commercial space. Unlike conventional multi-zone amplifiers, the MDX series is built with the discerning ear in mind, delivering not just power, but unparalleled fidelity.

At the core of its performance is the inclusion of Anthem Room Correction (ARC®) Genesis for every single zone—a first in this category. This revolutionary technology meticulously optimizes the audio for each individual room, correcting acoustic imperfections and ensuring every speaker delivers its full, intended performance. Paired with a sophisticated analog/digital audio matrix, the MDX series provides unprecedented flexibility, allowing any of its inputs to be routed to any output zone.

The amplifier section itself is a testament to our commitment to robust power. Delivering 60 watts/channel into 8 ohms and 120 watts into 4 ohms, and bridgeable to a powerful 200 watts into 8 ohms, the MDX series effortlessly drives a wide range of speakers, from in-wall units to high-performance stand-alone models. Designed for professional integration and flawless reliability, the MDX series is the definitive solution for high-end distributed audio.

Unwavering Power

Engineered for performance and reliability, the MDX series delivers robust, clean power to every channel. It provides 60 watts per channel into 8 ohms and 120 watts into 4 ohms, with the ability to bridge channels for a staggering 200 watts into 8 ohms. This ensures the MDX can effortlessly drive a wide range of speakers, from discreet in-wall units to more demanding bookshelf models. With our proprietary Advanced Load Monitoring (ALM™), the amplifier is always protected, providing flawless performance even under the most demanding loads.

A Sophisticated Audio Matrix

A multi-zone system requires absolute control, and the MDX series delivers with its sophisticated analog/digital audio matrix. This advanced system provides unprecedented routing flexibility, allowing you to seamlessly manage and distribute any of its inputs—including analog RCA, digital coaxial, and digital optical—to any output zone. Whether you’re streaming high-resolution music in one room or watching a movie in another, the audio matrix provides complete authority over every source.

Purpose-built for Installers

The MDX series is purpose-built for the discerning installer. Its design focuses on seamless integration, professional-grade control, and simplified setup. With a dedicated web-based user interface and comprehensive IP/RS-232 control, the MDX can be effortlessly integrated into leading home automation systems. Multiple units can also be daisy-chained for easy scalability in larger installations, providing a professional and powerful solution.

Zone-Independent Subwoofer Control

The MDX series provides superior control over bass management. It gives you the power to install and control subwoofers independently in separate zones, with dedicated outputs (both low- and high-level, including bridge mode). The true authority lies in its integration with Anthem Room Correction (ARC®) Genesis, which provides unique, zone-independent settings for each subwoofer. You can even toggle ARC on and off in each zone to audibly confirm the benefits of premium room optimization.

Total Authority Over Every Zone

The MDX series gives you complete authority over every zone in your system. Each zone can have its own custom name, multiple independent inputs, and separate playback controls, providing an exceptional level of personalization. For more power, you can effortlessly bridge zones to drive demanding speakers. You can also enable precise subwoofer bass management in any zone, instantly setting the crossover frequency, level, phase, and polarity. This remarkable level of control supports more creative system designs and delivers a more thrilling, high-fidelity audio performance.

Engineered for Performance and Scalability

The MDX series is engineered to support high-resolution source material, accepting inputs up to 24-bit/192kHz PCM. Its fast, efficient Ultra-Class-D platform is supported by our proprietary Advanced Load Monitoring (ALM™) technology, ensuring reliable performance under even the most demanding loads. This high-efficiency design also meets and exceeds global power-saving standards. For seamless expansion, smooth, instantaneous digital switching allows the linking of digital inputs between multiple MDX units, while analog pass-through connections enable effortless scalability for any size of installation.
