What is Astell&Kern?
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.
The 5 key performance measures of
The AK120 MQS Portable System goes beyond the standard Hi-Fi specifications.
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.
SNR (Signal to Noise Ratio) As the signal-to-noise ratio increases, the clearer the sound becomes. AK120’s SNR specification is 113dB.
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 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).
The updated GUI offers faster selection of your large library of music. Setting up the desired equalizer is also easy and is simple as a swipe of your fingers.
The main GUI consists of six (6) key icons to help navigate and play your favorites quickly. Touching the upper part of the main menu instantly brings you back to the “Now Playing” screen.
