The AK300 is equipped with a femto clock to deliver true original sound. Astell&Kern implemented a voltage-controlled crystal oscillator (VCXO) high-precision clock with a reference jitter value of 200 femto seconds. A VCXO is a type of crystal oscillation device that creates oscillation frequencies. External environmental stimuli, which in this case mean voltage inputs, influence the frequency value. Adjustments to the voltage input tunes a precise frequency value. The jitter that happens in this case is the error that occurs in the reference clock required to perform the sampling in digital audio equipment. By utilising a femto clock, the AK300 is able to create a more accurate frequency value and make fine jitter corrections. As a result, the AK300 faithfully reproduces analog sound closer to the original recording when transmitting a digital signal as an analog signal.
