The factory-specified cable colors are rarely used in most electronic devices. The Polytron PAS 28B tone control has two voltage inputs: 5 volts, +12 volts, and -12 volts. The problem is, the manufacturer uses unusual cable colors to represent these voltages, such as black for +12 volts, yellow for -12 volts, black with a red stripe for 5 volts, and red for center tap or CT. Of course, if audio enthusiasts aren't careful when assembling this tone control with another power source, the input voltage to the tone control will be incorrect, resulting in no sound or even causing the tone control and MP3 decoder module to be damaged. Therefore, I made this video so that everyone can understand the cable color symbols and the voltages required for this Polytron PAS 28 tone control. Hopefully, this is helpful. Keep up the spirit of spreading knowledge, the spirit of educating, the spirit of building the nation. Polytron speaker damage    • speaker polytron pas 68 suara cacat
