Technics SU-G700E-S silver

The gold standard in superior audio technology

As a worthy successor to the concept of reference audio technology, the JENO circuit transmits and processes audio signals entirely digitally with minimal jitter from the input stage to the power supply stage. LAPC (Load Adaptive Phase Calibration) technology provides ideal gain and phase characteristics for all types of speakers. The brand new low-distortion power supply is more precise, as it eliminates switching frequency fluctuations caused by load shifting.

JENO (Jitter Elimination and Noise-shaping Optimization) Circuit

To faithfully transmit the large amount of audio data to the speakers without any loss, the power amplification section of the SU-G700 implements a fully digital process based on the JENO circuit, which is founded on the concept of reference systems. To solve the problem of sound quality degradation due to jitter, which causes issues with traditional digital amplifiers, the SU-G700 features a proprietary jitter reduction circuit that eliminates jitter across the entire audible frequency range. In addition, an exclusive, high-precision circuit is used for PWM (Pulse Width Modulation) conversion, which is crucial for sound quality. By optimizing elements such as noise reduction speed and quantization degree based on our unique expertise, data from high-resolution audio sources, including those with a wide dynamic range, are converted to PWM signals without any loss. These technologies ensure the reproduction of sound in its finest details, naturally, allowing even subtle musical nuances to be perceived.

Ultra-fast, silent hybrid power supply

With a conventional switching mode power supply, the switching frequencies change according to load fluctuation in order to control the switching activation delay for output voltage stabilization. This fluctuation in switching frequency has a negative impact on audio quality. The brand new power supply reduces the noise component detrimental to audio quality by adjusting the switching frequency. Moreover, the final switching stage of the power supply is provided by a linear regulator that stabilizes the output voltage. The latter incorporates custom high-definition electrolytic capacitors.

Furthermore, our current resonance power supply reduces the level of switching noise. The parts used for noise absorption, such as capacitors, have been carefully selected. We have implemented every possible measure to achieve a low noise level and crystal-clear audio reproduction.
