Full Description
View Full DescriptionJENO Engine
The Technics JENO Engine (Jitter Elimination and Noise-shaping Optimization) is a proprietary technology developed by Technics to provide high-quality sound reproduction. The JENO Engine moderates jitter and optimizes the noise-shaping process to deliver a clear and focused sound. This technology is featured in some of Technics' most advanced audio systems, including the Technics SU-GX70, and is instrumental in establishing a more realistic listening experience.
Load Adaptive Phase Calibration
The question of matching an amp to speakers, like the Technics SU-GX70, can keep you up at night. Every system is unique. That’s why Technics have integrated LAPC (Load Adaptive Phase Calibration) into the Technics SU-GX70. It works by analyzing the characteristics of connected speakers and compensating gain and phase characteristics for each frequency band. This ensures sound waves from each speaker arrive at the listener's ears simultaneously, resulting in more natural sound reproduction.
Expansive Streaming
With the Technics SU-GX70, you get Chromecast, AirPlay 2, Spotify, TIDAL, Qobuz, Deezer, Amazon HD, and DAB/DAB+/FM and internet radio compatibility, as well as easy Bluetooth connectivity. This makes it so much more than a regular network amplifier. Whether entertaining guests or spending an evening alone, the Technics SU-GX70 is the perfect addition to any modern home.

Plus, with a headphone connection, you can enjoy your music in peace.
