Product Overview

Grand Class Network Audio Amplifier

A heavily featured streaming amplifier that combines the sonic genes of Technics Grand Class components with a wealth of source functions, including video connectivity, the SU-GX70 Network Audio Amplifier easily integrates into the home hi-fi system with the inclusion of an HDMI ARC port.

Full Digital Amp, JENO Engine (Jitter Elimination and Noise-shaping Optimization)

Twin Power Supply Circuit System

Ideal Impulse Response through LAPC (Load Adaptive Phase Calibration)

Pure Amplification Mode

High-quality Audio through Low-impact HDMI Video Output

Newly equipped HDMI® ARC with JENO Engine

Fully digital amplifier with Technics technology. Digital processing, less prone to degradation, offers high resolution but soft texture. A Technics first, the JENO Engine (Jitter Elimination & Noise-shaping Optimization) in the HDMI® ARC (Audio Return Channel) reduces degradation in sound quality from jitter during transmission of digital audio signals (S/PDIF) for unequaled clarity in TV audio.

Ideal Impulse Response through LAPC

A speaker impedance adaptive optimization algorithm, LAPC (Load Adaptive Phase Calibration), achieves ideal impulse responses with digital signal processing by measuring the amplifier’s frequency amplitude-phase characteristics with speakers connected. This flattens the frequency characteristics of amplitude and phase, previously not achieved, while delivering a rich spatial expression.

Abundant Input Options, Diverse Network Functions

The SU-GX70 supports a variety of music sources including radio, analog input (PHONO (MM)/LINE), optical digital input (such as a TV), coaxial digital input, and USB input. Also, the SU-GX70 can play back high-resolution music wirelessly from a smartphone, tablet, or PC. It supports not only Bluetooth® and AirPlay2 but also Spotify Connect®, Internet radio and Chromecast built-in™ so that a wide range of music streaming services can be enjoyed with only the SU-GX70.
