The device is equipped with stereo output for the second music zone but also has a built-in HEOS. The NR1608 has a complete set of relevant network interfaces for communication with the outside world. System configuration is done using Audyssey MultEQ.
Marantz NR1607 is a 7.2-channel receiver, assembled in a slim package. It works perfectly with the Dolby Atmos 3D sound format in 5.1.2 configuration. Also in the Marantz NR1608 vs Marantz NR1607 review, it needs to highlight the sound capabilities, since NR1607 does not have bi-amping, which significantly affects the operation of the amplifier and the sound as a whole. There is a built-in Bluetooth receiver and a 2-band Wi-Fi. AirPlay function supported. The presence of LAN and WLAN allows the receiver to connect to a local network. Speaker calibration is done by the Audyssey MultEQ system.
