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”.

32-bit 384kHz bit-to-bit Playback

All of the AK380 Copper’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 Copper is capable of playing back 32-bit, 384 kHz original sound without any down sampling.

The result is the AK380 Copper 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 Copper 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 forcalculating graphic equalizers (GEQ), allowing more detailed and accurate calculations via the dedicated DSP.

The audio DSP expands the existing 10-band, ±0.5 dB graphic equalizer (GEQ*2) to 20-band, ±0.01 dB to more precisely adjust the frequency and gain (dB) as well as more accurately specifying the frequency range via Q value adjustments.

* The PEQ supports up to 8 kHz - 192 kHz (8/16/24-bit) formats, but DSD and 32-bit audio are not supported.

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 AK380 Copper is able to create a more accurate frequency value and make fine jitter corrections. As a result, the AK380 Copper faithfully reproduces analog sound closer than ever to the original source when transmitting a digital signal as an analog signal.

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 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.

DMP (Digital Media Player)
Finds a list of content on a media server for selection and playback.
DMS (Digital Media Server = Network Server)
Actually stores the media content to be shared. When connected to a network, the DMS transmits/distributes the media content for other devices to stream or download.

DMC (Digital Media Controller)
Finds a list of content on a media server and establishes a connection to a playback-capable device (renderer). By default, a DMC establishes a connection between a media server and media renderer and controls content playback-related operations.
DMR (Digital Media Renderer = Network Player)
Connects to a media server via media controller for content playback.

Pressure-sensitive
Metal Capacitive Touch


The AK380 Copper 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 Copper offers great expandable options through its micro USB connection and balanced out 
ports on the bottom of the unit.


The AK380 Copper’s functionality is expandable by connecting to a variety of devices.
You can increase the output and connect to a greater variety of high-impedance professional headphones through the upcoming
AK380 Amp SS. The AK380 Cradle features balanced output in addition to USB data transfer and charging capabilities,
and the AK380 Copper CD-ROM drive rips audio CDs directly to the AK380 Copper.
