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*3.
Femto clocks are commonly used in high-end audio systems, and the clock is measured in high-precision femtosecond units (one quadrillionth of a second).
What is VCXO?
A VCXO, or a voltage-controlled crystal oscillator, 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.
What is Jitter?
Jitter refers to the undesired deviation in time that occurs in a periodic signal. In this case, jitter is the error that occurs in the reference clock required to perform the sampling in digital audio equipment.
By utilizing a femto clock, the AK320 is able to create a more accurate frequency value and make fine jitter corrections.
As a result, the AK320 faithfully reproduces analog sound closer than ever to the original source when transmitting a digital signal as an analog signal.
The AK320 supports USB DAC functionality.
The AK320 can be connected to a PC or Mac via USB for use as a USB DAC that supports PCM/DSD.
When playing back music stored on a PC or Mac, the Dual-DAC is able to deliver richer audio of outstanding soundstage and resolution well beyond the limits of a built-in sound card.
* When using the AK320 as a USB DAC, its PEQ settings are not applied, and output up to 24bit, 96kHz is supported.
* DSD 64/128 is converted via DSD-to-PCM for playback.
AK Connect App
Astell&Kern has further enhanced DLNA functionality via the AK Connect app.
Wireless networking DLNA (version 1.0) connects to a NAS or PC, and is easily controlled with a smartphone or tablet through AK Connect.
Source files on a PC or NAS can be freely transferred and streamed without the hassle of turning on the computer and physically connecting with a cable.
If on the same access point (AP) network, music files on a PC or NAS can be played back via DLNA.
Pressure-sensitive Metal Capacitive Touch
The AK320 features the same metal touch interface as the AK380.
The Metal Touch functions as a home key and interfaces
with the device via pressure-sensitive touches.
