Product Feature
1). Using the original TPA6120A and NE5534.
2). The main filter capacitor capacity using 2 × 3300UF, ensure strong support for a steady stream of power.
3). The selection of rings resistance metal resistance, the main circuit employs a precision of ± 1% metal film resistors rings, ensure the machine a good signal to noise ratio.
4). PCB using 1.6mm thick double-sided sheet, 2.0 oz copper thickness, HASL whole process to ensure that the size of the current through the good performance. PCB-class quality.
5). The entire circuit board trace layout is quite strict and reasonable, the overall PCB traces using a little grounding. In the dead of night almost hear the background noise contained headphones, very quiet.
6). Use UPC1237 and Hongfa relay output delay for protection
7). The two red switches corresponding channel gain switch.
