McIntosh MX123, A/V home theater processor

To satisfy the video needs of your home cinema, the MX123 has 7 HDMI inputs and 3 HDMI outputs. All HDMI inputs and outputs support HDCP 2.3; Rec. 2020; 4:4:4 color spacing; Dynamic Lip-sync; and 3D Video pass-through. To create the most life-like and realistic picture possible, all MX123 HDMI ports support a myriad of high dynamic range formats: HDR (static HDR); Dynamic HDR; HDR10+; HLG; and Dolby Vision (including low latency). These technologies will ensure that every moment of a video is displayed at its ideal values ​​for depth, detail, brightness, contrast, and color – on a scene-by-scene or even a frame-by-frame basis.

The 3 HDMI ports that are 8K/60Hz and 4K/120Hz compatible offer many other advanced features:

• Quick Media Switching (QMS) that eliminates the delay that can result in blank screens before content is displayed.
• Enhanced HDMI video features to improve gameplay performance by bringing an added level of smooth and seamless motion and transitions, including:
• Auto Low Latency Mode (ALLM) that allows the ideal latency setting to automatically be set allowing for smooth, lag free and uninterrupted viewing and interactivity.
• Quick Frame Transport (QFT) that reduces latency for smoother no lag gaming, and real time interactive virtual reality.
• Variable Refresh Rate (VRR) that reduces or eliminates lag, stutter and frame tearing for more fluid and better detailed gameplay.

The MX123 is also fully compatible with all the leading home theater surround sound and object-based 3D audio formats such as Dolby ^® Atmos (including Dolby Atmos Height Virtualizer); DTS: ^X® Through; Auro-3D ^® ; Sony's 360 Reality Audio, an immersive audio experience utilizing Sony's spatial sound technology; and MPEG-H Audio. MPEG-H Audio, primarily developed by Fraunhofer IIS, is an open ISO standard and the industry's most advanced audio system for UHD-TV and streaming. It supports both immersive sound and the ability for users to adjust elements in the audio to their preferences. MPEG-H has been on the air since 2017 on all TV networks in South Korea under the ATSC 3.0 standard. It was also selected for new broadcast standards to be launched in Europe, China and Brazil.

Audio Return Channel (ARC) and Enhanced Audio Return Channel (eARC) functionality is included on 1 of the HDMI outputs. ARC allows a compatible TV to send audio data to the audio video processor over the HDMI cable, eliminating the need for separate audio cables. The more advanced eARC offers greater bandwidth so higher resolution audio formats such as DTS-HD Master Audio ^™ , DTS:X ^® , Dolby TrueHD, and Dolby Atmos can be sent through the HDMI cable. ²

Additional connections include: 4 digital audio inputs; 1 balanced and 8 unbalanced analog stereo audio inputs (including 1 dedicated as a Moving Magnet phono input to connect a turntable); an unbalanced 7.1 multi-channel audio input; 3 component and 4 composite video inputs; 1 USB Type A input; 2 unbalanced analog stereo outputs; 2 composite video outputs; and 1 component video output.
