HF Microphone

HF microphones have many applications in stage sound. These mics are generally considered to be for TV presenters. HF microphones are microphones that use a separate receiver and transmitter to transmit sound.

The transmitter of these microphones sends the audio signals received from the microphone connected to it to the receiver via radio waves, and in this way you will receive the audio signals from the receiver device of the HF microphones.

Many characters and personalities in different programs need to move and there is no permanent place defined for them. Therefore, normal microphones cannot be used to record the voices of these characters. Here HF microphones help us to transmit audio signals.

Aside from the brand and manufacturer of a microphone, one of the most important parameters for purchasing a HF microphone is the reception of these devices. Most HF microphones are capable of transmitting audio signals up to a range of 100 meters or more.

HF microphones consist of three parts:

• Microphone
• Sender or transmitter
• receiver or receiver

The sound waves are received through the microphone capsule and are supplied to the transmitter in the form of analog audio signals. The transmitter's job is to convert analog signals into radio waves and send these waves to the receiver. In fact, the received analog signals are converted into digital signals.

After receiving the audio signals, the receiver converts these signals into analog signals and supplies them to you. Usually, these receivers are also connected to mixers to control the signal level and quality.

HF microphones have unique drawbacks. For example, you can easily and wirelessly receive the sound of the desired characters. But in addition to these advantages, these microphones also have disadvantages.

When we use radio waves for a communication between the receiver and the transmitter, the first thing that can come to someone's mind is the weak connection or break in these waves.

If you don't use a quality product for your program, you may encounter radio wave interference, which will cause serious problems for your work.

Another problem is the range in which the microphones can be used. Although many microphones claim to be able to send signals up to 100 meters, in some models we see that noise is created in the received audio signal as the distance between the receiver and transmitter increases.

When buying HF microphones, try to buy from reputable brands and never look for Chinese copies or counterfeit brands because these products can cause a lot of problems in your work and consequently reduce the quality of your work.

Another point is that the greater the distance between the receiver and the transmitter, the greater the possibility of radio wave interference in these microphones.

Another drawback of these microphones is their need for a power source, you will have less trouble with analog microphones to power your devices.
