Denon and Marantz AVRs Receive eARC and IMAX Enhanced Firmware Updates
A Sound United press release indicates that all eligible Denon and Marantz AVRs and processors are receiving eARC functionality, which is an HDMI 2.1 specification feature that’s backwards compatible with HDMI 2.0 gear. eARC allows uncompressed DTS:X and Dolby Atmos codecs (in addition to 7.1 Dolby Digital Plus, 7.1 Dolby TrueHD, 7.1 DTS-HD High Resolution Audio, and 7.1 DTS-HD Master Audio) to pass from a TV to a receiver or processor. In addition to other audio enhancements, eARC also unlocks a communication channel that allows an AVR to tell a TV which sound formats it supports, thus guaranteeing the best possible format is automatically selected.
IMAX Enhanced is also making its first appearance in both Denon and Marantz gear. Owners of the flagship X8500H and AV8805 AVRs will be the first to enjoy IMAX Enhanced content once it becomes available. According to Sound United: “With meticulous 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 immersive, powerful sound.”
AV NIRVANA has requested more information from IMAX, Xperi, and Sound United to further understand IMAX Enhanced and its true real-world impact.
Finally, Denon’s AVR-X8500 and Marantz’s AV8805 and SR8012 are getting a remote management boost at the hands of monitoring made available by ihiji and Domotz pro. This feature is meant for the custom install segment, further enhancing the brands' desirability in the home theater installer market.
