The SU-GX70 uses a fully digital amplifier that incorporates Technics' renowned digital audio technology. The digital transmission system processes signals fully digitally at all stages from input to output. Compared to analog transmission, this system is less susceptible to signal degradation caused by external noise, ensuring more accurate transmission. Precise signal processing not only provides high-resolution digital sound but also maintains the smooth sound produced by analog recordings.
