 What is Astell&Kern?

 
The Astell&Kern is the ultimate portable Hi-Fi audio system

The Astell&Kern is the ultimate portable high-fidelity audio system capable of playing Mastering Quality Sound (MQS), original sound, bit-to-bit, from music mastering studios. MQS refers to all of the high resolution digital music recording studio formats up to 24-bit/ 44 – 192kHz. MQS delivers vast amounts of better music experience because MQS delivers 6.5 times of the detailed information in the same track.  Astell&Kern is the way music is meant to be heard.


 



Equipped with the Wolfson 8740 DAC
 
Dual DAC, AK120
 
The AK120 not only meets the standards of Hi-Fi audio, but also utilizes two DACs (digital to analog converters) maximizing the dual-mono set up to completely separate and isolate the left and right audio channels. As a result, the AK120 delivers broader a dynamic range and wider soundstage so that you can enjoy an even more realistic music experience.  Enjoy the great MQS music up to 14 hours, which was made possible by the same ultra-low-power design unveiled with the AK100.

A Touch Equalizer Controlled by a Single Swipe


A Practical EQ Determines the Change in Frequency Response

 

With the Astell&Kern and a nice set of headphones, audio enthusiasts will appreciate even more various genres of music.  Use the touch interface of the built-in 5-band equalizer to delicately find the tone you desire.  In addition, touch the screen to finely adjust the value of each band.  


Professional Equilizer for the Best Soundstage

The AK120's Pro EQ was created from various genre of music after listening to them for thousands of times which helps to relive the live performance music. As an example, a single track has been listened to over 100 times for a time period of 40 minutes to achieve the best sound possible with this pro EQ setting. A good sound comes from a recorded piece expressed in the way it was meant to be heard. The focus with the Pro EQ feature is to create the soundstage through the sounds. In a quartet performance, the position of each of the 4 individual instrumentalists can be heard clearly. Through countless hours of testing and repeated listening the AK120's Pro EQ has been made. Experience the live soundstage of your music through the Dual DAC and Pro EQ feature of the AK120.



The 5 key performance measures of

Hi-Fi audio


The AK120 MQS Portable System goes beyond the standard Hi-Fi specifications.

 

The AK120 does not only meet the standards of Hi-Fi audio, but also utilizes two DACs (digital to analog converters), maximizing the dual-mono set up to isolate the left and right audio channels completely separate. In result, it delivers broader dynamic range and wider soundstage, so that you can enjoy even more realistic music.
 

 

 THD+N (1kHz 0dB, No load)

THD + Noise (Distortion) over the THD + Noise signal rate, less distortion is heard. The AK120 achieves a 0.0008% (Typ) distortion signal rate.


Signal to Noise Ratio (1kHz 0dB, No load)

SNR (Signal to Noise Ratio) As the signal-to-noise ratio increases, the clearer the sound becomes. AK120’s SNR specification is 113dB.


Crosstalk (1kHz 0dB, No load)

CROSSTALK The higher the number in the crosstalk specification, the higher the isolation in the Left/Right channels develops. The AK120 has a crosstalk specification of -128dB.

 
Frequency Response (1kHz 0dB, No load)

Frequency Response The frequency response specification of +0.02 to -0.02 in the AK120 provides a clear sound from Bass to Treble.


Jitter (1kHz 0dB, No load)

Jitter With smaller figures representing irregular tremors of the signal waveform, the better the device performs. The AK120 has a Jitter specification of 50ps(Typ).
