Technics SU-G700M2E-K black

The SU-G700M2 is a high-end 2x140 W (4Ω) amplifier that combines simplicity and performance. The successor to the SU-G700 features advanced technologies derived from the SU-R1000 in the high-end Reference series.

The benchmark for superior audio technology

A worthy heir to the reference audio technology concept, 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.

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. In addition, the last 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.
