Denon and Marantz Get IMAX Enhanced Update

Sound United has announced a firmware update that will make the Denon AVR-X8500 AV receiver and Marantz AV8805 AV preamp/processor the first AV components equipped with IMAX Enhanced technology.

IMAX Enhanced is a program developed by IMAX and DTS that certifies digitally remastered Ultra HD/HDR video with immersive 3D DTS surround sound for delivery through certified audio and video products that meet performance standards and incorporate a proprietary suite of IMAX and DTS technologies.

“As IMAX Enhanced content becomes available, owners of these products will have access to one of the most advanced audio and visual formats available,” said Sound United, the parent company of Denon and Marantz. “With meticulous adjustments modeled on how the IMAX theatrical sound system operates, this proprietary IMAX audio mix is translated for home theater environments and delivered using a special variant of the DTS:X codec technology integrated in home entertainment equipment to deliver immersive, powerful sound.”

The Denon AVR-X8500 and Marantz AV8805 will also receive a “smart remote management and Web UI” firmware update along with the Marantz SR8012 AV receiver.

Sound United also announced an eARC (Enhanced Audio Return Channel) firmware update for Denon and Marantz receivers that will provide support for additional formats, including Dolby Digital Plus (up to 7.1 channels), Dolby TrueHD (up to 7.1 channels), Dolby Atmos, DTS-HD High Resolution Audio (up to 7.1 channels), DTS-HD Master Audio (up to 7.1 channels), and DTS:X.
