Using the Astell&Kern
1. What is MQS?
o MQS stands for “Mastering Quality Sound” and refers to sound or music
files saved in a lossless format, straight from the studio-mastering source.
Because less data is lost during the digital mastering process and the
sound quality is distortion-free, a dramatic difference from the 24bit
source data contained in MQS files and CD (WAV)/MP3s can be heard
and felt.
o MQS files are often in 24bit WAV or FLAC formats. With the encoding
process in the AK100 MQS Portable System, MQS music and sounds are
more refined and pure.
MQS – 24bit, 96 – 192kHz
CD – 16bit, 44.1kHz
MP3 – 16bit, 128Kbps – 320Kbps, 44.1Khz
2. How can I tell if the power is turned on/off on the Astell&Kern?
o To verify if the Astell&Kern is turned on/off, please try these following
methods:

button.
If earphones are connected during music playback, you will hear a
tone from the earphones, indicating that the earphones are
