McIntosh, the global leader in prestigious home entertainment and ultimate-quality audio for over 65 years, is happy to announce the release of a free firmware update that brings full support for both DTS:X and Auro-3D* object-based 3D audio to the MX122 A/V Processor. Since its release earlier this year, the MX122 has had full support for Dolby® Atmos and now with this update, the MX122 supports all the leading object-based 3D audio technologies. The free update also adds DTS Neural-X as well as other minor improvements.
The MX122 can serve as the brain center for an advanced home theater system for years to come. It is fully compatible with modern 4K Ultra HD video sources and can upscale lower resolutions to 4K Ultra HD for the best possible picture quality. It combines the best-in-class audio performance of the legendary McIntosh Reference System with the latest in home theater technology.
To perform the update, the MX122 must be connected to a router that has internet access. This can either be a wired Ethernet connection or a wireless connection using the MX122 Wi-Fi capabilities.
To begin the update process, go to the following menu: Setup > General > Firmware > Update > Check for Update > Update > Update Start. The update process, electrical supply, and internet connection should not be interrupted during the firmware installation. (source)
