Its digital transmission system processes signals fully digitally in all stages from input to output.\u003c\/p\u003e\n\u003cp\u003eCompared 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.\u003cbr\u003e\u003cbr\u003eFurther, 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. \u003cbr\u003e\u003cbr\u003eHigh-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.\u003cstrong\u003e \u003cbr\u003e\u003cbr\u003eIdeal Impulse Response through LAPC\u003cbr\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSpeaker impedance changes with each frequency and a power amplifier is required to drive speakers without being affected by the speaker’s 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.\u003c\/p\u003e\n\u003cp\u003eAlso, although the amplitude characteristics of conventional amplifiers\u003cbr\u003edue to negative feedback were improved, the phase characteristics could not be enhanced.\u003cbr\u003e\u003cbr\u003eWe thus 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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003cbr\u003e\u003cstrong\u003e\u003cbr\u003eTwin Power Supply Circuit System\u003cbr\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 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 is equipped with a dedicated power supply for the power amplifier circuits that is independent from all other circuits.\u003c\/p\u003e\n\u003cp\u003eAs such, the same electrolytic capacitors installed in high-end models have been used in the dedicated amplifier power supply and the power amplifier components.\u003cbr\u003e\u003cbr\u003eFurther, by using the shortest possible connection between the power supply and the power amplifier, the SU-GX70 ensures low noise and low impedance. Elsewhere, the connections between the speakers and power amplifier use non-magnetic brass screws.\u003cbr\u003e\u003cbr\u003eThe SU-GX70 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.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eHigh-Quality Audio through Low-impact HDMI Video Output\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eFor the SU-GX70 to receive audio signals through the HDMI ARC (Audio Return Channel), due to the specifications, video signals must first be output from the SU-GX70. However, the output of these signals can cause unwanted noise.\u003cbr\u003e\u003cbr\u003eAs such, the video signals are output from the SU-GX70 at a lower rate, and the digital value of the colour of each pixel is set to zero. This ensures low-load operation between the HDMI transmitting\/receiving devices, preventing any unwanted noise generation from the video signals.\u003cbr\u003e\u003cbr\u003eThis also reduces any impact on sound quality. Further, transmitting the signals from the TV to the JENO Engine via the shortest possible route minimises any further impact from jitter. This is a mechanism unique to Panasonic\/Technics as HDMI licensors. \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePure Amplification Mode\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eIn Pure Amplification Mode, shutting off the power supply to the network and HDMI circuits removes any noise from the device or antenna.
