All-in-one Module SEM3

SEM3 is an Interchangeable All-in-One module for the SE180
Shape your Sound with the ESS ES9038Q2M Quad DAC SEM3
Give your SE180 a different sound than the bundled module
SEM3 supports up to 32bit/768kHz / Native DSD512

Next Generation Advanced AMP Technology

Next generation AMP technology is also applied in the SEM3 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.



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.

The SEM3 is equipped with four ES9038Q2M DACs, this allows two DACs per channel for dedicated decoding. The SEM3 achieves a more detailed and balanced sound with great depth and spatial realism.
