For the rest, we find the exclusive Class G Dynamic Audio Amplification (high current, low impedance architecture to precisely manage large speakers), an EI transformer, a slightly higher total power of 2 x 160 W under 6 ohms, gold-plated RCA connectors, a rich connectivity and the presence of a digital radio tuner [abc]Dab+[/abc] and AM/FM RDS with forty presets. Not to mention two high-capacity capacitors and a rigid chassis that allows you to enjoy all kinds of musical sources with the best sound quality.
The Asahi Kasei 384 KHz/32-bit digital-to-analog audio converter offers [abc]Hi-Res Audio[/abc] certification. It is combined with VLSC (Vector Linear Shaping Circuitry) technology to eliminate ultra-high frequency interference.

The connections include four stereo [abc]RCA[/abc] inputs including a Phono MM/MC input, a [abc]coaxial[/abc], two [abc]optical[/abc], a Zone 2 stereo Pre Out output via stereo RCA, a Pre-Out output to transform the TX-8470 into a pre-amplifier if it is associated with a power amplifier, a [abc]USB[/abc] Host port on the front, a powered USB Host port on the rear to power a dongle for example, an [abc]Ethernet[/abc] port, plus a subwoofer output and a headphone jack.
The Onkyo TX-8470 also has four HDMI [abc]CEC[/abc] 2.0 inputs compatible with [abc]ALLM[/abc], [abc]VRR[/abc], [abc]HDR10[/abc], [abc]HDR10+[/abc], [abc]HDR HLG[/abc] and one [abc]HDMI[/abc] [abc]ARC[/abc] output.
