The evolution of a masterpiece, AK380
The purpose of Astell&Kern is to keep the sound quality as close as possible to the original. The AK380 geared for the pro sound group and audiophiles who demand the very best. A masterpiece, we introduce 'AK380' to you.
32bit/384kHz Bit to Bit Playback, Native DSD Playback, 20Band EQ/0.1dB steps, VCXO Reference Clock(200 Femto Seconds), Extendible Docking connector, AK Connect App, Metal-touch sensor Home button
In order to become a device the professionals want, we decided that make a bold move which was to restart all processes from the beginning.
The device the professionals want, now AK380 is the start.
Since Astell & Kern has discontinued production of some repair parts, please contact ECT Customer Service Center for further details on repair service, Tel.: (852) 2708 7180, thank you.
32-bit 384kHz bit-to-bit Playback
All of the AK380’s circuit design including the digital-analog converter (DAC) are ready for 32-bit processing to handle 32-bit music natively. Other products have traditionally used sample rate converter (SRC) method down sampling for playback. However, the AK380 is capable of playing back 32-bit, 384 kHz original sound without any down sampling. The result is the AK380 plays up to 32-bit, 384 kHz, any 24-bit music files, or double layer DSD 5.6MHz natively, without conversion or compression.
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
(VCXO) high-precision clock
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).
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 AK380 offers great expandable options through its micro USB connection and balanced out ports on the bottom of the unit.
