A New Approach to Music We at Astell&Kern have been relentlessly searching for just the right raw material to complement sound. Stainless steel has given us unwavering strength Duralumin, a material used in aircraft, has given us high rigidity and light weight Aluminum has given us excellent wear resistance We selected copper as the principal raw material for the newest variant of the AK380 to convey the message that this is more than just a medium for transmitting music - it's an “instrument”. Witness the birth of a new instrument - The AK380 Copper
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.
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.
(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
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 AK380 is the first Astell & Kern product to utilize a metal capacitive touch interface. The pressure-sensitive Metal Touch home button responds to fine pressure changes so users operate the device with just a light touch on the metallic pad.
More Expandable Options
The AK380 offers great expandable options through its micro USB connection and balanced out ports on the bottom of the unit.
