MARANTZ. AV7701 has all of the video processing you'd want in a new component, including the ability to upconvert SD and HD content to 4K high resolution video (3840x2160) for future displays. It also features all of the latest digital audio decoders, for Dolby TrueHD, Dolby Pro Logic IIx, and DTS-HD Master Audio. There's also an option for additional front height or front width channels, as well as a bi-amp mode for the front main (L/R) speakers. The AV7701 can even deliver new entertainment, through a host of networking features. Once the unit is connected to the web, it can stream Pandora, SiriusXM and Spotlify (assuming you have a subscription), as well as thousands of web radio stations.
