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.
