Common audio equipment commonly mentioned impedances are the impedance of the speaker, the input impedance of the front and rear amplifiers, the output impedance of the front stage, (the latter stage is usually not called the output impedance, but the output internal resistance), the transmission of the signal line Impeding resistance (or characteristic impedance) ... etc. Since the unit of impedance is still ohms, Ohm's law is also applicable, so in short, at the same voltage, the higher the impedance, the less current will flow, and the lower the impedance, the more current will flow. The most common value of the speaker impedance is eight ohms, which means that when the pair of speakers is tested at the factory, when the 1KHz sine wave signal is input, the impedance value it presents is eight ohms; or it is the response at the working frequency of the speaker Within the range, an average impedance value. It is not a fixed value, but varies with frequency. When the rear stage outputs a fixed voltage to the speaker, according to Ohm's law, a four-ohm speaker will flow twice as much current as an eight-ohm speaker. It will automatically change to two hundred watts when a four-ohm speaker is installed. When the impedance value of the speaker drops all the way, the rear stage outputs a fixed voltage, and the current flowing through it will become larger and larger. In the end, it is a bit like directly shorting the speaker wire, so the impedance value may sometimes be as low as one ohm. Limits, beyond this range, the machine will burn out. This is what most people often say: the power of the post stage does not need to be large, but the output current should be large.
