Technics SU-GX70 Network Integrated Amplifier

A 40 Wpc digitally controlled class-D amp with MM phonostage, HDMI ARC, FM tuner, and headphone amp

The definitive living room audio center that enables seamless enjoyment of video, audio, and music through next-level integration using Technics’ full digital technologies.

A heavily featured streaming amplifier that combines the sonic genes of Technics Grand Class components with a wealth of source functions, including video connectivity, the SU-GX70 Network Audio Amplifier easily integrates into the home hi-fi system with the inclusion of an HDMI ARC port.

The JENO Engine

The SU-G700M2 power amp section uses full digital amplification employing the JENO Engine that uses a unique, high-precision PWM (Pulse Width Modulation) conversion circuit that lets an input signal stay digital all the way to the output stage.

The LAPC Advantage

Speaker impedance changes with frequency, and a power amplifier is required to drive speakers without being affected by the speaker’s characteristics. Conventional digital amplifiers are connected to speakers through a low-pass filter at the output stage, so they are even more strongly affected by the speaker impedance characteristics.

Technics has developed a speaker-impedance adaptive optimization 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. This new technique enables flattening the frequency characteristics of amplitude and phase, which had previously not been achieved by amplifiers, as well as delivering a sound with rich spatial expression.
