New Japanese Chemical Filter Capacitor.

In order to solve the problems of low reliability caused by the use of potentiometers in traditional volume control, sliding noise in contact, dynamic reduction when the volume is low, and narrowing of frequency response, a relay switching method is used as the volume control, which can conveniently adjust the volume. It not only saves the trouble of connecting external volume boards, but also shortens the signal flow of music channels, and helps improve sound quality. Pure resistance circuit, higher fidelity!
