The primary goal of Astell&Kern has always been to deliver the original sound,and we believed that the AK380 did just that.

We wanted even more people to experience the AK320 and its ability to deliver the original sound as intended.

- AK4490's Dual-DAC, DSD-to-PCM Playback - Parametric EQ with 20bands 0.1dB - 200 Femto Second VCXO Reference Clock - Exceptional Expandability - DLNA-based AK Connect App - Metal Touch

 

24bit 192kHz bit to bit Playback

AK320 is capable of bit-to-bit playback up to 24bit, 192kHz. 32bit audio is downsampled using a sample-rate converter (SRC). In addition, DSD 64/128 can be played back via conversion to PCM. * 32bit, 384kHz is downsampled to 24bit, 192kHz, and 32bit, 352kHz is downsampled to 24bit, 176kHz for playback. * DSD 64/128 is converted via DSD-to-PCM to PCM 24bit, 176kHz for playback.

 

PEQ (Parametric EQ)

A parametric equalizer (PEQ*1) was implemented in the AK380 to deliver detailed adjustment of the original sound, and an audio digital signal processor (DSP) was added to aid in this process. This frees up CPU cycles previously needed for calculating gra

 

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).

 

USB DAC

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.

 

More Expandable Options

The AK320 can be expanded to a variety of devices through the micro-USB and balanced audio out ports located at the bottom of the product. It can be connected with the AMP as well as professional high-impedance headphones for high output and USB for data transfer and charging. It can also be connected to the Cradle for balanced audio functionality as well as the CD-RIPPER to conveniently rip audio CDs.
