Large low-phase noise quartz oscillator precision clock reduces timing jitter
Timing jitter degrades the digital audio signal, creating an unevenness and introduces distortion into the sound. A large,
low-phase noise oscillator precision clock provides a timing signal to all the parts of the digital audio system, so each
process can be triggered at the right moment.
