A NEW STANDARD IN LUXURY HOME THEATER
The MX124 A/V Processor invites you to experience cinematic excellence in the McIntosh way: where engineering excellence meets the art of storytelling so that everything is connected and nothing is compromised. With 13.4 channels of immersive audio, stunning 8K Ultra HD clarity, and the vivid realism of advanced HDR, the MX124 transforms every viewing into an event. With the latest in advanced processing and a design built for performance, it delivers a level of home entertainment that is unmistakably McIntosh.
 
UNMATCHED IMMERSIVE AUDIO WITH FOUR SUBWOOFERS
The MX124 places you squarely at the center of the action with 13.4 channels of powerful, precise audio. Its 13 audio channels and 4 subwoofer outputs allow for immersive configurations such as 7.4.6 or 9.4.4, creating a sonic environment where every detail, from the softest whisper to the deepest bass impact, is fully realized. Its 4 dedicated subwoofer outputs are twice as many as the previous model, delivering an even more impactful bass performance.
 
Compatible with today’s leading surround formats – including Dolby® Atmos, DTS:X® Pro, Sony 360 Reality Audio, and MPEG-H Audio – the MX124 ensures studio‑grade accuracy. Nine 32‑bit audiophile-grade DACs provide pristine digital-to-analog conversion, while bass and treble controls allow you to tailor the system to your personal listening preferences.

Two HDMI outputs serve the main video zone, with the third output allowing independent video playback in a second zone.  Every HDMI port is engineered to deliver the very best in video performance with compatibility with High Dynamic Range (HDR) formats Dolby Vision™, HDR10+, and HLG for exceptional depth, contrast, and color accuracy on a scene-by-scene or even a frame-by-frame basis. The MX124 is also IMAX® Enhanced for elevated picture precision and powerful, theater‑grade sound.
