Description

All-in-One Module SEM4

SEM4 is an interchangeable all-in-one module for the SE180. With its release, Astell&Kern has expanded the potential of the SE180 once again. SEM4, born from the key concept of ‘Shape Your Sound’ is equipped with the AK4493SEQ dual DAC, the latest DAC from Asahi Kasei, which minimizes loss and noise interference from the original sound while offering 14 hours of playback performance — the longest among SEM modules. SEM4 supports up to 32bit/768kHz, Native DSD512 and you will be able to enjoy even more vivid, original sound with the introduction of digital audio remaster (DAR) technology.

Equipped With Asahi Kasei AK4493SEQ Dual DAC

The SEM4 module is equipped with a dual AK4493SEQ DAC, the latest product from Asahi Kasei, which has been implemented in an Astell&Kern product for the first time worldwide. The AK4493SEQ DAC is a premium DAC that utilizes AKM’s VELVET SOUND™ technology to play natural sounds with even lower noise and distortion, offering the best low distortion traits and a wide dynamic range. With technology such as the advanced switch and capacitor that is created to achieve low-power consumption, it provides amazing play performance and low noise for 14 hours of playback, the longest among SE180 modules.

Supports Native DSD512, 32bit/768kHz

SEM4 supports Native DSD512 and up to 32bit/768kHz with Astell&Kern’s excellent audio technology, allowing you to fully enjoy your favorite music.

Digital Audio Remaster Technology for Even More Vivid Original Sound

SEM4 features digital audio remaster (DAR) technology — the first time the technology has been applied in an Astell&Kern portable player. DAR technology is developed to up-sample the sample rate of the sound source being played to go beyond the limits of the source format. The high sample rate allows more refined play and offers delicate and analog-like original sound, helping you to enjoy the richness of the original sound, subtle differences in the nuance of the music and rich sounds at a higher level.
