JENO engine (Jitter Elimination and Noise Shaping Optimization)
Jitter is the main cause of interference in digital transmission systems. It is caused by clock deviations used in digital to analog conversion. In order to eliminate jitter problems affecting sound quality, Technics has developed a new jitter suppression circuit. It consists of a clock generator in the noise shaping system, which reduces jitter in the low frequency range, and a precise sampling rate converter, which suppresses jitter in the high frequency range.
Jitter is thus ideally reduced over the entire frequency range. This solution is based on a newly developed, original PWM (Pulse Width Modulation) conversion circuit that optimizes the speed and extent of noise shaping, requantization error and PWM grading so that high resolution signals are converted to PWM without affecting the dynamic range. These new technologies allow Technics next-generation digital amplifiers to reproduce the natural and subtle nuances of music.
