McIntosh, a manufacturer with decades of credibility in high-end audio, has unveiled the MX124 A/V processor, a powerhouse designed to handle complex home theater installations with ease. This announcement marks a significant step forward for buyers planning premium audio and video setups, offering capabilities that rival or exceed what competitors deliver at this price tier.
A Speaker Configuration Powerhouse
The MX124 supports speaker layouts up to 13 audio channels with configurations like 7.4.6 or 9.4.4, making it ideal for installations ranging from standard surround setups to fully immersive Dolby Atmos-equipped rooms. What distinguishes this processor is its four independent subwoofer outputs, double the number found in McIntosh’s previous model. For shoppers investing in premium speakers for every room size, this flexibility means you can tune bass performance with precision across multiple zones without compromising the rest of your audio chain.
The processor incorporates nine premium 32-bit digital-to-analog converters, ensuring that the detail and dynamic range your high-quality speaker systems can produce actually reaches your ears without degradation. Bass and treble controls provide additional fine-tuning, allowing you to match the processor’s output to your specific room acoustics.
Immersive Audio Support and Room Correction
The MX124 supports all major immersive audio formats: Dolby Atmos, DTS:X Pro, Sony 360 Reality Audio, and MPEG-H Audio. This comprehensive format support ensures that whether you’re streaming the latest blockbuster or listening to spatial audio music content, the processor can decode and deliver it properly. Buyers upgrading their home theater won’t face obsolescence as new formats emerge.
Room correction is handled through three licensed solutions: Dirac Live Room Correction, Dirac Live Bass Control, and Audyssey MultEQ XT32. Rather than locking you into a single calibration approach, McIntosh lets installers and owners choose the solution best suited to their setup. This flexibility preserves what audiophiles value most: the natural musicality and tonal character that define McIntosh’s sound signature.
Video Capabilities for Next-Generation Displays
On the video side, the MX124 includes seven HDMI inputs and three outputs, with support for 8K/60Hz and 4K/120Hz on all primary connections. This future-proofs your investment as 8K content slowly becomes available and gaming at 4K/120Hz becomes mainstream. The processor also handles Dolby Vision, HDR10+, and IMAX Enhanced, covering the major high-dynamic-range standards you’ll encounter.
Additional video technologies include HDCP 2.3 (copy protection), Variable Refresh Rate for gaming, Auto Low Latency Mode, and 3D passthrough. Multi-zone support is built in: two HDMI outputs feed your main theater, while a third provides independent video playback elsewhere in your home.
Music Streaming and Network Control
The MX124 integrates streaming from Apple AirPlay, Spotify Connect, TIDAL Connect, and Qobuz Connect, plus it is Roon Ready with support for high-resolution audio up to 32-bit/192kHz. If you own portable speakers for travel or other audio components, the ability to stream consistently across your home ecosystem eliminates the frustration of incompatible platforms.
Control4 Simple Device Discovery Protocol certification means the MX124 integrates cleanly into whole-home automation systems. Web-based configuration, IP control, and RS232 support give installers and tech-savvy owners the tools they need to manage complex setups remotely or through third-party control systems.
Specifications and Pricing
Key performance specs include a frequency response of 20 to 20,000Hz with just 0.5dB variation, total harmonic distortion of 0.005% in DSP bypass mode, and a signal-to-noise ratio of 96dB at high output levels. These figures translate to clean, transparent audio reproduction across the frequency spectrum.
The processor weighs 29 pounds and measures 17.5 by 7.75 by 17 inches, making it suitable for standard AV equipment racks. McIntosh has priced the MX124 at $15,000, positioning it as a premium option for serious home theater enthusiasts and professional installers. Given the feature set, immersive audio support, and flexibility it provides, buyers comparing processors in this category should evaluate whether the investment aligns with their long-term system goals.
The MX124 is available exclusively through authorized McIntosh dealers, ensuring you receive proper installation guidance and support from someone familiar with the brand’s philosophy and capabilities.
