Denon and Marantz Release AVR Update Including IMAX Enhanced

Sound United has announced that Denon and Marantz AVRs will receive several new firmware updates as of today, which will include the following:

1. eARC (Enhanced Audio Return Channel). A feature introduced for HDMI 2.1, eARC will allow for additional formats to be transported which are detailed in the list below. Moreover, eARC includes a mandatory information channel telling the TV which sound formats are supported by the AVR so that the TV outputs the best possible format automatically:

Dolby Digital Plus (up to 7.1 channel

Dolby TrueHD (up to 7.1 channel)

Dolby Digital Plus (up to 7.1 channel)

Dolby Atmos

DTS-HD High Resolution Audio (up to 7.1 channel)

2. IMAX Enhanced. The Denon AVR-X8500 and Marantz AV8805 will be the first receivers equipped with IMAX Enhanced technology. As IMAX Enhanced content becomes available, owners of these products will have access to “one of the most advanced” audio and visual formats available. With adjustments modeled on how the IMAX theatrical sound system operates, this proprietary IMAX audio mix is translated for home theatre environments and exclusively delivered using a special variant of the DTS:X codec technology integrated in home entertainment equipment to deliver “powerful” immersive audio.

3. Smart Remote Management (SRM) and Web UI. Audio, video, speaker and input functionalities will support via web UI for the Denon AVR-X8500H, Marantz AV8805, and Marantz SR8012. This Web UI and remote monitoring and management are made available by ihiji invision and Domotz pro.

  1. It seems to me that "IMAX Enhanced" is just a new way IMAX can make money thru licensing just like G. Lucas did with THX. I wonder why IMAX doesn't shoot some new documentaries or lend their cameras to directors to shoot with, rather than releasing their "Remastered" features so they can charge higher ticket prices while deafening the audience.
