The SA-C600 uses a fully digital amplifier incorporating Technics’ renowned digital audio technology. Its digital transmission system processes signals fully digitally in all stages from input to output. Compared to analogue transmission, this system is less susceptible to signal degradation caused by external noise, ensuring more precise signal transmission. Accurate signal processing not only delivers high-resolution digital audio but also maintains the soft texture inherent in analogue recordings.

The design of the power supply is extremely critical in audio systems containing CD players, amplifiers, digital circuits and other such components. To eliminate any adverse effects on the amplifier, the SA-C600 is equipped with a dedicated power supply for the amplifier circuits that is independent from all other circuits, supplying power to the two independent transformers. The wiring connections between the two dedicated transformers and the amplifier circuits are also optimised for noise reduction.

The power supply for the clock circuit of the JENO Engine utilises the same noise suppression circuit employed in Technics’ flagship turntable model, the SL-1000R, in order to improve noise reduction. It achieves superb sound image localisation and transparent spatial expression.

The built-in phono equaliser supports MM cartridges. The phono equaliser uses a dedicated power supply and is equipped with a power supply circuit that is different from the control circuit for improved noise reduction. The equaliser circuit also features a shielded construction to shut out the effects of external noise and allows for signal amplification without any loss of fidelity.

The SA-C600 is equipped with a Space Tune function that enables the adjustment of sound to suit the environment and location of the unit so that anyone can enjoy superb music reproduction. By using the Technics Audio Centre* app for tablets and smartphones or by selecting one of the four presets on the main unit—Free, Wall, Corner and Shelf—the user can achieve the most suitable sound reproduction for their specific acoustic environment.
The L/R Custom feature allows users to enter separate settings for each individual speaker, adjusting for installation under different conditions and bringing out the best sound quality in any environment.

To ensure consistency of appearance, the design of the SA-C600 incorporates elements from Technics turntables such as colour, texture and dimensions, improving the aesthetics of the system. The aluminium top panel sports a built-in CD player with a manually operated lid for ease of use and functional beauty.
