Onkyo TX-NR686 review

In addition to the main 7.2 channels - the last two of which can be used both for the rear and for the speakers of the “upper” channels in the Dolby Atmos or DTS setup: X - TX-NR686 is equipped with additional amplification channels for connecting a pair of speakers in the second zone. And given the receiver's output power, which is 165 watts per channel (6 ohm), even with fairly demanding acoustics, it should not have any problems. The device has a good set of physical inputs, it has seven HDMI connectors with HDCP 2.2 support.
