Full Digital Amp, JENO Engine
The SU-GX70 uses a fully digital amplifier that incorporates Technics’ renowned digital audio 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.
Further, 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.
High-quality audio components have been used in various other locations, too. For example, chip film capacitors have been used in place of power supply noise-reduction capacitors and signal path coupling capacitors.
Space Tune™ for Optimal Adjustmentof Sound Quality
The SU-GX70 is equipped with the “Space Tune” function, which enables the adjustment of sound space according to the room environment and installation location so that anyone can enjoy superb music reproduction.
By using the “Technics Audio Centre app for tablets/smartphones or by selecting a setting from the four presets—“Free,” “Wall,” “Corner” and “In a Shelf”—using the main unit according to the installation location, the user can achieve the most suitable sound quality for a specific acoustic environment.
Furthermore, the L/R Custom feature lets the user enter the setting independently for the left and right speakers when the speakers are set up in different installation conditions. This brings out the best sound reproduction in any installation conditions.
