What is the Portable MQS System? Astell&Kern is the ultimate portable high-fidelity audio system capable of studio Mastering Quality Sound (MQS)
Source frequency analysis comparison
Noise Detected during Balanced Output Noise Removed After Detection Noise Removal Complete DSD Playback support High-Definition Digital Audio Formats and DSD Playback support with the AK120
In common digital audio recording, PCM(Pulse Code Modulation) is the Y-axis of a sine wave is divided into 65000 (16bit) to 1,670 million(24bit) and the X-axis is divided into 44,000(44.1kHz) to 192,000(192kHz) parts. When comparing a standard PCM digital recording to the DSD approach, the digital signal is transformed by Y-axis of the DSD sine waves that are measured at single bit(1bit, 0s and 1s) sequence and is divided 2.8 million(2.8MHz) to 5.6 million(5.6MHz) times into the X-axis.
In general, when comparing SACD and PCM 16bit/44.1kHz Audio CDs, SACDs are recorded in frequency ranges up to 100kHz and greatly expand the dynamic range over 120dB while maintaining clarity of sound that a traditional PCM audio signal cannot reproduce. In order to listen to SACD, a dedicated SACD player is needed, but the AK120 brings SACD audio format playback to a portable player with DSD audio support. Enjoy the sound of DSD without a separate SACD player with the AK120. (AK120 supports the .dff and .dsf DSD formats up to 2.8MHz resolution.)
PCM DSD Meets the Standards of Hi-Fi Audio
Equipped with the Wolfson 8740 DAC AK120 DAC & Amp Creates a Dual Mono System that separates Left & Right Audio Channels
24-bit/192kHz, SNR, THD+N → Hi-Fi Audio Spec External DAC Support Use the AK120 as an external DAC through the USB port.
/*21-09-09 수정*/ Total memory
The AK120 comes with 64GB of high-speed internal flash memory and dual microSD memory card slots capable of supporting up to 64GB of memory in each slot. Store up to 192GB of high-resolution audio with the AK120.
4 generations of MQS Albums supported on microSD cards
The additional memory card slot holds an important point. 24-bit album recordings will soon be released with music files stored in microSD memory cards. For a mainstream album, LP (vinyl) records would be considered as first generation, second generations are cassette tapes, and Compact Discs (CDs) is the third and current generation. Fourth generation albums are considered as MQS albums that are released in high capacity microSD memory cards. Comfortably enjoy two albums at once through the dual memory card slots of the Astell&Kern.
- The Astell&Kern supports MQS high-resolution music stored on microSD cards.

Q. My first experience with Astell&Kern
Q. The history and development of Pro EQ
It would be a marvelous journey of music when you are listening to the Astell&Kern with its Pro EQ setting, and we hope you can also experience Yu’s philosophy on the most realistic sound.
UI with an Integrated Touch Screen and Control Buttons The AK120 offers very intuitive user experience through a more robust and sensitive touch screen.

DESIGN
The brushed aluminum pores finish represents a deep and refined craftsmanship not traditionally found in a combination.
More solid and refined design impression of the AK120
The design of the volume wheel protector resembles the bridge of a stringed instrument and hints at the more enriched sound from the AK120. Luxurious details are not missed at all with the AK120. The red ring wrapped around the volume wheel is a design statement of the Astell&Kern identity and the fine craftsmanship of all metal components reassures the long lasting quality of the Astell&Kern.
