What is the impedance of the Microphone? What effect does the microphone sound quality?

When using Micro, there are many parameters we need to pay attention to. In particular, impedance has an essential role in affecting the sound quality, performance and sensitivity of the Microphone. So what is the impedance of the Micro? What are some effects of impedance on a Microphone? Please refer to the following article with Tnhelearning.edu.vn!

What is Microphone Impedance?

Micro impedance is an important part of Micro, helping us to know the resistance of alternating current in the circuit, when voltage flows through. In other words, impedance is the resistance of alternating current.

The unit of impedance is the ohm , similar to the resistance, so it is often called the AC resistance. If your home microphone has noise or signal loss, it is due to high microphone impedance. Therefore, when choosing to buy a Micro, you should choose a product with a low impedance , with a value of about 50 – 600 ohms .

Impedance is also applied in another way to move the impedance to the microphone as follows:

• When a voltage is applied to the signal , the Micro impedance controls the alternating current.
• All AC resistors in general or Micro in particular have output impedance.
• The output impedance is always less than the input impedance of the microphone.
• The Micro load impedance is the input impedance, creating a circuit with the preamp to which the Micro is connected.

Some effects of Micro impedance you should know

According to the definition of Microphone impedance above, impedance plays an important role in creating good, smooth sound quality . If the impedance is higher, the Microphone will be noisy and lose signal, as well as the sensitivity of the Mic is weaker.

The best operating range of Micro impedance is in the range of 50 – 600 ohms . You should choose to buy a low-impedance microphone, because the mic has less resistance, helping to reduce noise and signal loss. Some common impedance ranges in microphones are as follows:

• Less than 600 ohms : Low impedance microphone.
• About 600 – 10000 ohms : Micro has medium impedance.
• Over 10000 ohms : High impedance microphone.
