Product details:Refer to well-known preamp circuit design.Working in a single end Class A state, the sound quality is delicate and vivid, round and smooth, with a strong musical flavor and extremely high musical clarity..
Advanced double-sided thickened gold-plated PCB (2MM substrate, 75U copper foil thickness) with dual channel design.
Left and right independent field transistor stabilized power supply，highly separated.
New Japanese Chemical Filter Capacitor.
Audio amplification using American IRF610/9610 field-effect transistors.
Taiwan YONTEX MKP axial coupling capacitor.
Resistance of Military 718 Factory.
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!
