With its launch, Astell&Kern has expanded the potential of the SE180 once again.
Born from the key concept of "Shape Your Sound", the SEM4 is equipped with the AK4493SEQ dual DAC, Asahi Kasei's latest DAC, which minimizes loss and noise interference of the original sound while delivering 14 hours of playback performance, the longest among SEM modules.
The SEM4 supports up to 32bit/768kHz, native DSD512 and you can enjoy even more vivid and original sound with the introduction of digital audio remastering (DAR) technology, the first time this technology has been applied in an Astell&Kern portable player.
DAR technology has been developed to increase the sampling rate of the sound source being played to go beyond the limits of the source format.
The high sampling rate allows for more refined playback and delivers a delicate, analog original sound, allowing you to enjoy the richness of the original sound, the subtle nuance differences of the music, and the richness of the sounds at a higher level. .
Supported DAR options:
- Maximum conversion rate.
- PCM 44.1kHz range will be converted to 352.8kHz for playback.
- The 48kHz PCM range will be converted to 384kHz for playback.
- No conversion will be performed when playing DSD with this option selected.
- PCM DSD files below 96kHz will be converted to DSD128 for playback.
- PCM files above 96kHz will be converted to DSD256 for playback.
- DSD files below DSD256 will be converted to DSD256 for playback with this option selected.
- New generation advanced AMP technology.
The next generation AMP technology is also applied in the SEM4 all-in-one module. From OP-AMP parts selection, to circuit design, board layout and tuning, everything has been completely redesigned to produce the best sound.
Separation structure of system unit and module circuit.
The complete physical separation of the system unit and the DAC module perfectly prevents power noise and RF noise from the system unit, meaning no noise will interrupt your music.
In addition, the separation of signals by balanced and unbalanced channels without interference offers the best sound.
TERATON ALPHA is A&K's ultimate sound solution for producing audio reproduction close to the original sound through the audio output interface by using effective power noise removal, efficient power management and amplification. with minimal distortion.
TERATON ALPHA features Astell&Kern's patented technologies, which are the result of tens of thousands of hours of continuous research and development to produce a sound close to the original sound that the artist and producer intended.
