![]() Power 120W (8 ohms, 20Hz - 20kHz) with two channels driven Users can also stream content wirelessly using Apple AirPlay 2, Bluetooth aptX HD, Google Chromecast, Spotify Connect, Roon and Tidal Connect. ![]() There’s also an aerial connector for an FM/DAB tuner, a USB port and trigger outputs with IR extenders for two zones, along with an RS-232 serial connector and an Ethernet port for wired network connection. Physical connections at the rear also include an array of six digital (four coax, two optical) and six analogue (RCA) audio inputs, as well as optical and analogue outputs and pre-amp outputs. All of these HDMI ports can handle 8K video signals at 60fps and 4K at 120fps with support for VRR, ALLM, Dolby Vision and HDR10+. One of the outputs also supports eARC Though its number of power amplifier channels may leave something to be desired, there’s nothing lacking about the AVR31’s connectivity spec, with a healthy seven HDMI 2.1 inputs and three outputs. ![]() The AVR31 is the only AV receiver in Arcam’s new line-up that benefits from class-G amplification to deliver a claimed 100W per channel with all channels driven, as well as an over-engineered toroidal transformer to help reduce noise. ![]() Class G is essentially a variation of A/B amplification that uses voltage rail switching to help maximise the amplifier's efficiency. ![]()
