JENO Engine (Jitter Elimination and Noise Shaping Optimization)
The SU-G700M2 uses a fully digital amplification principle in the output stage including the JENO Engine (Jitter Elimination and Noise Shaping Optimisation) so that the large amount of data in the music signal is transmitted to the loudspeakers true to the original and without loss. Here, too, a consistent orientation to the Technics reference class is implemented. The jitter reduction circuit developed by Technics is also used in the SU-G700M2 to prevent unwanted clock jitter in the entire audible frequency range. In contrast to conventional digital amplifiers, the sound impairment caused by jitter is effectively suppressed. In addition, a unique, high-precision PWM converter circuit is used, which promotes high sound quality. Even music data in the high dynamic range, such as that found in high-resolution music, is converted into PWM signals without loss. For this purpose, the speed and degree as well as the quantization number of the noise shaping have been optimized. These technologies enable an outstandingly natural and detailed reproduction that opens up even the finest nuances in the music to the listener.

LAPC (Load Adaptive Phase Calibration)
A speaker’s impedance changes with frequency. The power amplifier must drive the speakers regardless of their specific characteristics. Conventional digital amplifiers drive the loudspeakers via a low-pass filter in the output stage. As a result, the influence of the impedance characteristics of the connected speakers is much greater. Although negative feedback can be used to control the amplitude characteristics of conventional amplifiers, optimization of the phase characteristics is not possible. Therefore, Technics developed an adaptive speaker impedance optimization algorithm. It corrects the impulse response of the speaker using digital signal processing. To do this, he measures the amplitude-phase characteristics of the amplifier with the loudspeakers connected. This new method enables the frequency response characteristics of amplitude and phase to be smoothed, which is not possible with conventional amplifiers. The timing of the resulting amplifier signal leads to a sound image with precise spatiality.

High-performance switching power supply Advanced Speed ​​Silent Power Supply
The power supply technology used in the reference model SU-R1000 has been used for improved speaker performance and a better sense of energy. The switching frequency has been increased from the traditional 100kHz band to the 400kHz band to ensure stable supply of voltage and current and reduce the negative impact of modulation noise on audio quality. The device is equipped with the same GaN-FET and SiC SBD as the SU-R1000 to achieve the maximum performance of the high-speed switching power supply system.
In addition, a super-low-noise control is planned for a later phase. It prevents the regulation from decreasing due to the fixed switching frequency and prevents the mixing of noise components with high frequencies. The result is a low-noise and responsive power supply that maximizes the performance of the digital amplifier.

High sound quality thanks to the three-part structure
High sound quality thanks to the three-part structure
There is a wide variety of circuits in integrated amplifiers, including circuits that handle micro-signals at the inputs and those that handle large currents, such as output circuits and power supply circuits. The SU-G700M2 uses a three-piece construction with partitions between circuit blocks arranged according to the signal level to be processed. This avoids interference between the circuit blocks and achieves clear sound quality. In addition to the three-piece construction, the SU-G700M2 features a bottom chassis with a two-layer construction of 1.2mm and 2mm thick steel plates, a top made of 1.6mm thick steel plates, and a 7mm-thick aluminum front panel for better vibration absorption.

Low-noise phono input
PHONO MC input is now supported. A low-noise field effect transistor (FET) in differential parallel connection is used in the input stage to reduce noise. A four-stage gain setting results in optimal adjustment to the pickup system used. This gives the user complete freedom in terms of their equipment and listening environment.

Class AA headphone amplifier
The Class AA headphone amplifier has separate amplification circuits for the voltage and current amplification of the headphone signal. An operational amplifier that can handle high currents is responsible for amplifying the current. The high-resolution PWM output signal from the JENO engine is converted into an analog signal with great precision. The result: the headphones are optimally controlled. Regardless of the impedance of the headphones, this technology allows music playback with optimally minimized distortion in an ultra-wide frequency range.
