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).
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 theater 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 utilizing Sony’s spatial sound technology; and MPEG-H Audio.
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 MX123 features upgraded digital audio processing capabilities that results 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 both balanced and unbalanced audio outputs that can be used in a variety of home theater speaker configurations; 2 additional unbalanced outputs offer further connection flexibility. DSD and ALAC playback support have 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 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.
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.
Music streaming options3 on the MX123 includes 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 just 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 theater’s unique acoustical properties, letting it deliver the clearest and most balanced earth-shattering sound possible. Each discrete audio channel has its own 32-bit premium Digital-to-Analog Converter (DAC) to produce the best audio quality. Bass and treble tone controls plus a 9-band equalizer offer additional fine-tuning. The MX123 also gives you the flexibility to create 2 additional zones in your house and send select audio and/or video to each zone.
