The SU-GX70 is a definitive living room audio centre that enables seamless enjoyment of video, audio, and music through next-level integration using Technics’ full digital technologies. It produces stunning sound.
Fully digital for pure sound
The SU-GX70 uses a fully digital amplifier that incorporates Technics’ renowned technology. Its digital transmission system processes signals fully digitally in all stages from input to output. Compared to analogue transmission, this system is less susceptible to signal degradation caused by external noise, ensuring more precise signal transmission. Accurate signal processing not only delivers high-resolution digital audio but also maintains the soft texture inherent in analogue recordings.
JENO Engine
A JENO Engine has been used in the HDMI ARC (Audio Return Channel), which
has been installed in a Technics product for the first time. This helps to reduce any 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 (Load Adaptive Phase Calibration)
Technics have developed a speaker impedance adaptive optimisation algorithm that 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. This technique enables flattening of the frequency characteristics of amplitude and phase, which had previously not been achieved by amplifiers, while also delivering a sound with rich spatial expression.
Twin power supply circuit system
The SU-GX70 uses a high-speed switching power supply of approximately 130kHz. Noise interference on the music playback bandwidth is reduced, enabling a highly responsive power supply for music signals and powerful speaker drive capability.
High-quality music and audio from video source
Equipped with an HDMI ARC, low-impact HDMI video output ensures you can enjoy high-quality music and audio from the video source.
Compatible with a variety of music sources
Supports a variety of music sources including radio, analogue input, optical digital input (such as TV), coaxial digital input and USB input.
Enjoyment of high-quality sound wirelessly
It can play back high-resolution music wirelessly from the source stored in a smartphone, tablet or PC. It supports not only Bluetooth and AirPlay2 but also Spotify Connect, Internet radio and Google Cast.
