McIntosh today announced an 8K compatibility upgrade for its high-end MX123 A/V Processor. Although there’s no model number change, all new units shipping this month (September 2021) will be updated to support 8K/60Hz and 4K/120Hz video resolutions and refresh rates (HDMI 2.1). The new MX123 will also be able to upscale lower resolutions to 8K.
First launched in October 2019, the 13.2-channel MX123 home theater preamplifier/processor appears visually unchanged except for rear inputs. Of its 10 HDMI inputs and outputs, one of the inputs and two of the outputs will have 8K/60Hz and 4K/120Hz support (all 10 will continue to support 4K/60Hz). The three HDMI ports that are 8K/60Hz and 4K/120Hz compatible will also offer many other advanced features including Quick Media Switching (QMS); Auto Low Latency Mode (ALLM); Quick Frame Transport (QFT); and Variable Refresh Rate (VRR).
All 10 of the HDMI ports support HDCP 2.3; Rec. 2020; 4:4:4 color spacing; Dynamic Lip-sync; and 3D Video pass-through. And all 10 will also now support a myriad of high dynamic range formats such as HDR (static HDR); Dynamic HDR; HDR10+; HLG; and Dolby Vision (including low latency).
In addition to these exciting video upgrades, the MX123 will continue to offer an impressive list of audio capabilities: 13.2 audio channels; Dolby Atmos (including Dolby Atmos Height Virtualizer); DTS:X Pro; Auro-3D; Sony’s 360 Reality Audio; MPEG-H Audio; IMAX Enhanced; eARC/ARC; Apple AirPlay 2; Bluetooth; Spotify Connect; and Audyssey MultEQ XT32.
