Features:
1.The fully enclosed dust-proof potentiometer, performance is more stable, more durable than ordinary potentiometer.
2.PCB used 1.6 mm thick double-sided board, 1.6 oz copper thick, tin the whole process, to ensure good through the performance of the size of the current.
3.The main loop of the resistance to choose high precision SMD resistor, plus or minus 1% of the rings metal film resistors, precision to ensure the machine good signal-to-noise ratio.
