McIntosh MX122 processor firmware update adds DTS:X and Auro-3D

The McIntosh MX122 A/V Processor can serve as the brain center for an advanced home theater system for years to come. It features many of the latest breakthroughs in surround sound and object-based 3D audio: Dolby® Atmos is supported, and with a free firmware update both DTS:X™ and Auro-3D® are also supported. Besides 3D audio, existing formats like Dolby TrueHD, DTS-HD Master Audio™ and others still work so you can keep enjoying your existing movie collection. Regardless the format, all audio will be processed to legendary McIntosh sound quality and performance standards. The McIntosh MX122 is also fully compatible with modern 4K Ultra HD video sources and can upscale lower resolutions to 4K Ultra HD for the best possible picture quality.

Digital brain advanced home theater system

The enjoyment the MX122 delivers does not have to be confined to just one room; you can create 2 additional zones in your house and have the MX122 send select audio and/or video to them. A wide assortment of inputs and outputs will let you connect your current and future entertainment sources. Inputs include 7 HDMI, 4 digital audio, 1 balanced and 8 unbalanced analog stereo, an unbalanced 7.1 multi-channel audio, 3 component and 4 composite video along with 1 USB for iPod. Outputs include both balanced and unbalanced connections configured for 11.2 (also referred to as 7.2.4) surround sound, 3 HDMI (1 dedicated for “zone 2”), 2 component and 2 composite video (1 of each for “zone 2”) and 2 unbalanced stereo (1 for “zone 2” and 1 for “zone 3”). All HDMI inputs and outputs are HDCP 2.2 and support High Dynamic Range (HDR), 4K Ultra HD at 50/60Hz, 4:4:4 color, Rec. 2020 and 3D video pass-through.

Incredible versatility

Besides enjoying your favorite movies and TV shows, the MX122 is also great for listening to analog or digital 2-channel music in either stereo or upconverted to surround sound and is compatible with a variety of high resolution digital music formats up to 24-bit/192kHz. You can connect to your cloud-based or online digital music with either the wired or wireless network connections. DSD64 files can be played from flash drives or over your network. Bluetooth and AirPlay® connectivity allows for easy streaming from your mobile devices. Interfaces to popular streaming services1 including Pandora®, SiriusXM® and Spotify® are included while vTuner lets you connect to 1,000s of internet radio stations – including McIntosh Music. Audyssey MultEQ® XT32 will calibrate the MX122 to your home theater’s unique acoustical properties, letting it deliver the clearest and most balanced – yet still earth shattering – sound possible. Each audio channel has its own 32-bit premium DAC for the best audio performance. A 9 band equalizer offers additional fine-tuning.

Publisher

Marco Lisi is the publisher of Best of High End, part of AV Concepts BV. His path into audio started early: as a teenager he was drawn into the world of free radio, presenting shows and living immersed in music every day. In his early twenties he ran his own production studio for five years, creating jingles and commercials — hands-on training in sound design, pro-audio workflows, and critical listening through studio monitors that still shapes how he evaluates gear today. He also spent years DJing in clubs before moving into publishing, first at two earlier online magazines before founding Best of High End. His hi-fi and home cinema passion was inherited from his father, an inveterate system-swapper. Marco's first setup — a confirmation gift — paired AKAI separates with entry-level Bowers & Wilkins speakers, a brand he stayed loyal to for years as his system grew from stereo into full surround and home cinema. Like many enthusiasts, he went through an extended "audiophile" phase chasing the next upgrade, before settling into a more grounded view: gear as a means to enjoy music and film, not an end in itself. Years of critical listening have given him a well-trained ear — the ability to characterize a system or pinpoint a change in the chain quickly and accurately. Just as important, his teaching background (a Belgian "regent" degree in Dutch language) gives him the tools to translate those listening impressions into clear, readable writing.
