Astell & Kern SEM2 is an Interchangeable All-in-One module for the SE180. Shape your Sound with the Asahi Kasei AK4497EQ Dual DAC SEM2 module. The SEM2 module allows you to give your SE180 a different sound than the bundled module. The SEM2 supports up to 32bit/768kHz bit-to-bit playback and Native DSD512.

Next Generation Advanced AMP Technology
Next generation AMP technology is also applied in the SEM2 all-in-one module. From the selection of OP-AMP parts, to circuit design, board layout and tuning, everything has been completely redesigned to produce the best sound. Even with a high output, the signal-to-noise (SNR), one of the important measurements of audio performance, boasts an amazing 127dB (based on AK4497EQ Dual, Balanced, High Gain).

Circuit Separation Structure of Main Body and Module
By physically separating the main body from the All-in-One module, we completely block power and RF noise that may occur from the main body. This creates an independent structure that prevents noise from interfering with music playback. Balanced and unbalanced signals are separated for each channel to provide the best possible sound through independent circuit design without interference.

TERATON ALPHA Sound Solution
TERATON ALPHA is AK's ultimate Sound Solution to produce audio playback that is close to the original sound through the audio output interface by use of 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 sound close to the original sound the artist and producer intended.
