High-Precision PWM Modulator

High-Precision Triangular Waves

Distortion or irregular angles of the triangular waves lower the precision of PWM signals, which results in lower sound quality. The JCV8015 uses high-precision triangular waves to prevent the problem.

Ultra-High-Speed Comparator

Comparison of audio signals with the triangular waves is done by “comparator”. The JVC amp features an ultra-high-speed comparator. This prevents the possible delay of PWM signals with respect to audio signals, which causes distortion.

Synchronization by an External Clock

Slight gap of frequencies among channels causes specific noise. To prevent this, the JVC amplifier uses an external clock, which synchronizes the operations of all channels. Noise is also generated when the unit receives AM signals whose frequency overlaps that of audio signals. The external clock detects this and automatically modifies the audio signal frequency of all the channels simultaneously, thus preventing the noise generation.
