Transmission distance up to 10M
High operating efficiency, up to 90%
Using the original TPA3116 NE5532
The main filter capacitor uses a special electrolytic capacitor capacity of 3300UF, the other imported, to ensure a strong stream of dynamic support.
Resistance selection of high-precision chip resistors, the main circuit using precision ± 1% of the five ring metal film resistors to ensure a good signal to noise ratio.
PCB using 1.6mm thick double-sided sheet, 1.5 oz copper thickness, spray tin the whole process, to ensure the size of the current through the good performance. First-class PCB quality.
Fully enclosed dust-proof potentiometer, more stable performance, more durable than ordinary potentiometers.
Red ring with high current inductor, to ensure crisp and powerful sound.
