In 2019 Marantz introduced new slim-case AV receiver, the older model in this series - 7.2-channel Marantz NR1710 AV receiver. See this Marantz NR1710 review for Marantz NR1710 specs and other interesting features.
The Marantz NR1710 AV Receiver is a 7.2-channel AV receiver with a low case and full 3D sound thanks to the support of the DTS: X and Dolby Atmos formats in 5.1.2-channel configuration. The Marantz NR1710 model works with the DTS Virtual: X format, which allows you to create an imitation of the sound of ceiling speakers in ordinary surround sound systems that are not equipped with specialized speakers. The receiver also knows how to scale any video to 4K resolution. Seven high-current discrete amplifiers provide 90 watts per channel at 6 ohms, and the AV receiver works reliably even with a 4-ohm load.
There is a Bluetooth circuit on board, AirPlay 2 support is announced with the possibility of organizing a multi-room system based on iOS devices. The model copes with the role of a streamer, playing on a local network and USB Hi-Res-audio formats (PCM up to 24 bit / 192 kHz and DSD up to 5.6 MHz).
The Marantz NR1710 AV receiver has one HDMI input on the front and seven HDMI inputs on the back. All of them support HDCP 2.2 protocol and 4K resolution (60 Hz), as well as HDR10, Dolby Vision and HLG video standards with extended dynamic range. There is an HDMI output with eARC return channel and an MM phono equalizer. There are coaxial and optical inputs, 2.2-channel Pre Out and one Pre Out for the second zone. Speakers are connected to seven pairs of screw terminals, each of which is marked with a specific color.
Audyssey MultEQ helps calibrate speakers. In addition, the model uses technologies to optimize volume and frequency response - Dynamic Volume and Dynamic EQ. Audyssey MultEQ system is used to set up the speakers in accordance with the geometry and acoustic features of the room. The technology uses Dynamic Volume (normalizes the volume, which is convenient when watching broadcasts with ads) and Dynamic EQ (optimizes the frequency response in order to get full sound in a wide frequency band with full-weight bass even at low volume levels).
