JENO Engine (Jitter Elimination and Noise-shaping Optimization)

Just like the R1, the SU-C700 is a fully-digital amplifier and delivers high-resolution digital signals without any distortion being introduced between the input stage and output to the speakers. Technics has developed an original jitter-reduction circuit, avoiding the sound quality degradation due to jitter common to conventional digital amps. It uses a clock generator for the noise-shaping system to reduce jitter in the low-frequency range and a high-precision sample rate converter to suppress jitter in the high-frequency range.

LAPC (Load Adaptive Phase Calibration)

Technics has developed a speaker impedance optimization algorithm, using digital signal processing to flatten both the amplitude and phase-frequency response to make the most of your speakers. The result is a sound with better focus, spaciousness and definition.

High-speed Silent Linear Power Supply

Using a large-current Schottky-barrier diode, a rectifier circuit with electrolytic capacitors, and a stabilized power supply circuit, the SU-C700 ensures ample power supply at all times, even when dynamic music demands high current.

Battery Driven Clock Generator

Technics used battery power for low-noise applications in analog amplifiers in the past: here, this same technology is used to improve digital clock precision, enhancing the definition of the sound.

Various Inputs

The SU-C700 supports a wide range of inputs, such as SPDIF, Analog and Phono, as well as USB-DAC for connection of a PC. The digital input terminal supports coaxial 192-kHz/24-bit PCM and optical 96-kHz/24-bit. The USB DAC input terminal supports 192-kHz 32-bit PCM and 2.8-MHz/5.6-MHz DSD native playback (analog output) and asynchronous transmission. The SU-C700 converts analog signals to high-precision 192-kHz/24-bit PCM signals using the A/D converter. The full-digital system achieves high-purity reproduction from any content.
