Technics SU-G700E Integrated Amplifier

Inheriting the reference-class audio technology concept, the JENO Engine transmits and processes audio signals in full digital and with minimal jitter from the input stage to the power stage. Speaker load adaptive phase calibration (LAPC) ensures ideal gain and phase characteristics for any type of speaker. The newly developed low-distortion switching power supply realises accurate power supply by suppressing switching frequency fluctuations caused by load shifting.

Optimally Activated Circuit System

The Optimally Activated Circuit System allows the operation of various digital modules to be stopped – such as those used for display, analogue and digital interfaces – to minimise the noise generated when music is playing.

High-quality Analogue Circuit

Analogue input is converted with high precision to a digital signal by the high quality 192-kHz/24-bit A/D converter [Burr-Brown PCM1804 (Texas Instruments)], so the high-purity sound reproduction capability of the full-digital system can be maximised in playing back analogue sources. High-definition switching relays are used for signal switching.

JENO Engine (Jitter Elimination and Noise-shaping Optimization)

In order to faithfully transmit the massive amount of audio data sent to the speakers without loss, the SU-G700 power amp section uses full digital amplification employing the JENO Engine, based on the design concept of reference systems. In order to solve the issue of sound quality degradation due to jitter, which poses problems for conventional digital amplifiers, the SU-G700 has an original jitter reduction circuit that eliminates jitter over the entire audible frequency range. Also, a unique, high-precision PWM (Pulse Width Modulation) conversion circuit is used for PWM conversion, which is important for sound quality. By optimising items such as the noise-shaping speed, degree, and quantization number through our unique expertise, data even in the wide dynamic range contained in high-resolution sound sources is converted to PWM signals without loss. These technologies provide reproduction of natural and finely detailed sound, enabling perception even of delicate music nuances.

Battery Driven Clock Generator

The best power supply for delicate circuitry such as the clock generator in new amplifiers is one entirely isolated from any noise or fluctuations in the mains supply. Technics has extensive experience in power supply isolation using batteries. This technology creates ultra-low-noise pre-amplifier stages.

Low-noise PHONO Input

The PHONO input achieves low noise by using a differential parallel connection configuration of a first-stage, low-noise FET. In addition, four-level gain adjustment enables selection of the best gain according to the cartridge output. This enables optimal playback of high-grade analogue recorded sound sources tailored to the user’s environment.
