Technics SU-GX70EB Grand Class 2 Channel (Stereo) Network Amplifier
Technics SU-GX70EB Grand Class 2 Channel Stereo Network Amplifier
![]()
Product Features Full Digital Amp, JENO Engine (Jitter Elimination & Noise-shaping Optimisation)
Further, 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.
Ideal Impulse Response through LAPC (Load Adaptive Phase Calibration)
So Technics 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.
Twin Power Supply Circuit System
The 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.
