Full digital amplifier

The SU-GX70’s digital transmission system processes signals fully digitally in all stages from input to output for accurate signal processing that delivers high-resolution digital audio that maintains the soft texture inherent in analogue recordings.

JENO engine

A JENO Engine has been used in the HDMI ARC, helping reduce degradation in sound quality caused by jitter during the transmission of digital audio signals (S/PDIF), ensuring unparalleled levels of clarity in TV audio.

Ideal impulse response through LAPC

A speaker impedance adaptive optimization algorithm performs correction to the ideal impulse response through digital signal processing by measuring the frequency amplitude-phase characteristics of the amplifier with the speakers connected.

Twin power supply circuit system

The SU-GX70 is equipped with a dedicated power supply for the power amplifier circuits that is independent from all other circuits.

Analogue input using discrete amp circuits

The discrete amp circuit used in the SU-GX70 was redesigned and adapted from the circuit used in the SU-R1000, and the same symmetrical layout has been used.

High-quality music and audio from video sources

Equipped with an HDMI ARC, low-impact HDMI video output ensures users can enjoy high-quality music and audio from the video source.

Compatible with a variety of music sources

The SU-GX70 supports a variety of music sources including radio, analogue input (PHONO(MM)/LINE), optical digital input (such as TV), coaxial digital input and USB input.

Enjoy high-quality sound wirelessly

The SU-GX70 can play back high-resolution music wirelessly stored in a smartphone, tablet or PC. It supports Bluetooth, AirPlay2, Spotify Connect, Internet radio and Chromecast built-in so you can enjoy a wide range of music streaming services.
