Shape your Sound with SEM2
- SEM2 is an Interchangeable All-in-One module for the SE180
- Shape your Sound with the Asahi Kasei AK4497EQ Dual DAC SEM2
- Give your SE180 a different sound than the bundled module
- SEM2 supports up to 32bit/768kHz / 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.
