Full Digital Amp, JENO Engine<\/h4>\n

The SU-GX70<\/strong> uses a fully digital amplifier that incorporates Technics<\/strong>\u2019 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.<\/p>\n

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.<\/p>\n

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.<\/p>\n

Ideal Impulse Response through LAPC<\/h4>\n

Speaker impedance changes with each frequency and a power amplifier is required to drive speakers without being affected by the speaker\u2019s characteristics. However, conventional digital amplifiers are connected to speakers through a low-pass filter at the output stage, so they are even more strongly affected by the speaker impedance characteristics. Also, although the amplitude characteristics of conventional amplifiers due to negative feedback were improved, the phase characteristics could not be enhanced.<\/p>\n

We thus developed a speaker impedance adaptive optimization 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.<\/p>\n

Twin Power Supply Circuit System<\/h4>\n

The design of the power supply is extremely critical in audio systems containing amplifiers, digital circuits and other such components. To eliminate any adverse effects on the amplifier, the SU-GX70<\/strong> is equipped with a dedicated power supply for the power amplifier circuits that is independent from all other circuits. As such, the same electrolytic capacitors installed in high-end models have been used in the dedicated amplifier power supply and the power amplifier components.<\/p>\n

Further, by using the shortest possible connection between the power supply and the power amplifier, the SU-GX70<\/strong> ensures low noise and low impedance. Elsewhere, the connections between the speakers and power amplifier use non-magnetic brass screws.<\/p>\n

The SU-GX70<\/strong> uses a high-speed switching power supply of approximately 130 kHz. By increasing the switching frequency, noise interference on the music playback bandwidth is reduced. This enables highly responsive power supply for music signals and powerful speaker drive capability.<\/p>\n
