The MX123 A/V Processor marries a long tradition of uncompromising McIntosh sound quality with the latest home theatre technologies to bring you an unsurpassed luxury home entertainment experience. The MX123 supports 8K/60Hz and 4K/120Hz resolutions and refresh rates. It can also upscale lower resolutions to 8K to produce the best possible picture quality.
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 colour 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 every moment of a video is displayed at its ideal values for depth, detail, brightness, contrast, and colour – on a scene-by-scene or even a frame-by-frame basis.
Of the 10 HDMI ports, 1 input and 2 outputs are 8K/60Hz and 4K/120Hz compatible with the rest supporting 4K/60Hz.
The MX123 is also fully compatible with all the leading home theatre surround sound and object-based 3D audio formats such as Dolby® Atmos (including Dolby Atmos Height Virtualizer); DTS:X® Pro; Auro-3D®; Sony's 360 Reality Audio, an immersive audio experience utilising 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 users' ability to adjust audio elements 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 to launch new broadcast standards 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.
The 3 HDMI ports that are 8K/60Hz and 4K/120Hz compatible offer many other advanced features:
Quick Media Switching (QMS) eliminates the delay resulting 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) sets the ideal latency setting, allowing for smooth, automatic, lag-free and uninterrupted viewing and interactivity.
Quick Frame Transport (QFT) 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 features upgraded digital audio processing capabilities, resulting in 2 more discrete audio channels, bringing the MX123 to 13.2 discrete audio channels compared to 11.2 in the previous model. These 13.2 discrete channels are available via balanced and unbalanced audio outputs that can be used in various home theatre speaker configurations; 2 additional unbalanced outputs offer further connection flexibility. DSD and ALAC playback support has been doubled to DSD128 and ALAC 192kHz for better high-resolution audio performance.
Additional connections include 4 digital audio inputs; 1 balanced and 8 unbalanced analogue 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 analogue stereo outputs; 2 composite video outputs; and 1 component video output.
The MX123 is IMAX® Enhanced compatible. IMAX Enhanced is a set of stringent performance standards established by IMAX and DTS® to create a consistent and higher bar for image and sound performance on premium devices. It uses a sophisticated, advanced algorithm to produce the highest-quality, sharpest 4K HDR images. IMAX and DTS will also partner with award-winning Hollywood sound mixers to use a special DTS:X codec technology variant in the MX123 to deliver an IMAX signature sound experience in your home theatre.
Music streaming options on the MX123 include Apple® AirPlay 2® along with Bluetooth® and Spotify® Connect for easy streaming from your mobile devices. AirPlay 2 is an Apple technology designed to control home audio systems and speakers in any room – with a tap or by asking Siri – right from an iPhone®, iPad®, HomePod™, or Apple TV®. It offers multiroom audio, Siri voice control, and enhanced playback. TuneIn is also included for further music streaming options. To assist with wireless streaming performance and reliability, it includes 2.4/5GHz dual-band support. An ethernet port that lets you make a hardwired connection to your network is also included to aid in producing the best possible music streaming experience.
Audyssey MultEQ® XT32 is included and will calibrate the MX123 to your home theatre’s unique acoustical properties, letting it deliver the clearest and most balanced earth-shattering sound possible. Each discrete audio channel has a 32-bit premium Digital-to-Analog Converter (DAC) to produce the best audio quality. Bass and treble tone controls plus a 9-band equaliser offer additional fine-tuning. The MX123 also allows you to create 2 additional zones in your house and send select audio and/or video to each zone.
The MX123 has received Connects with Control4 Certification from Control4®, a leading global provider of smart home automation solutions, with the implementation of their Simple Device Discovery Protocol (SDDP), allowing it to be effortlessly integrated into Control4 automation systems to enhance the user experience further. It has also received Works with Crestron Home certification from Crestron, a global leader in advanced smart home technology. Crestron Home unlocks the full potential of a smart home.
