Technics SU-C700EG-silver

JENO Digital Circuit

As with the R1 system, the SU-C700 is a digital class amplifier that transmits high-resolution digital signals without distortion from the input stage to the speakers. Technics has developed its own jitter reduction circuit, avoiding sound quality degradation due to jitter in traditional digital amplifiers. It incorporates a clock generator within the noise reduction circuit to reduce jitter at low frequencies. It also includes a high-precision sampling converter to suppress jitter at high frequencies.

LAPC

Technics has developed a speaker impedance optimization algorithm using digital signal processing, enabling a linear “amplitude/phase” curve that adapts to most speakers. The result is more precise, spatial sound with better definition.

Ultra-fast, Linear, and Silent Power Supply

By using a Schottky diode, a rectifier circuit with electrolytic capacitors, and buffer stage power supply, the SU-C700 ensures an ideal power supply at all times, even when the music dynamics demand more current.

Battery-powered Clock Generator

Technics used battery power to create an ultra-low noise preamplifier stage in its older analog amplifiers. This same technology is now perfected to ensure high precision of the digital clock, enhancing sound definition.
