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 and is instrumental in establishing a more realistic listening experience.
Load Adaptive Phase Calibration
The question of matching an amp to speakers can keep you up at night. Every system is unique. That’s why Technics have integrated LAPC (Load Adaptive Phase Calibration). It works by analysing 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.
Twin Power Supply
This unit is equipped with a twin power supply for both digital and analogue circuits. Fundamentally isolated from one another, the high-speed switching power supply circuit uses damping materials to absorb vibrations and reduce noise. As a result, the power supply operates practically silently, allowing for clear and precise audio output. This is a sophisticated quasi-resonant power supply upgraded directly from the premium SA-C600 network receiver.
Expansive Streaming
With Chromecast, AirPlay 2, Spotify, TIDAL, Qobuz, Deezer, Amazon HD, and DAB/DAB+/FM and internet radio compatibility, as well as easy Bluetooth connectivity, this is so much more than a regular network amplifier. Whether entertaining guests or spending an evening alone, this is the perfect addition to any modern home.
Flexible Physical Connectivity
Easily connect a TV or other HDMI devices to enjoy high-quality sound with the available HDMI ARC input. The USB A / B connections also offer lossless playback potential, while the line and digital inputs round out the plethora of choices to connect to. Plus, with a headphone connection, you can enjoy your music in peace.
Low-noise MM Phono
The Technics Grand Class grade low-noise Phono MM input is a premium audio input that is designed to minimize noise and distortion whilst giving you a direct connection to your turntable. Technics use high-quality components to ensure precise sound reproduction, an excellent choice for the discerning audiophile.
