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, 32-bit/768kHz

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

System Unit and Module Circuit Separation Structure

The complete physical separation of the system unit and the DAC module perfectly prevents noise from the power and RF noises from the system unit, meaning no noise will interrupt your music.

In addition, the separation of signals by balanced and unbalanced channels with no interference delivers the ultimate sound.
