All You Need To Know About Wireless Microphones

The arrival of wireless microphones was a real revolution in the world of audio since it largely eliminated the main nuisance for these assemblies such as the profusion of cables.

However, for sound quality there was no comparison in favor of wiring. With the evolution of technology, what was an abyss of difference has been significantly shortened until reaching similar qualities depending on the models. The same thing has also happened with prices.

Currently, there is a wide catalog of wireless microphones that offer multiple possibilities for both performance and pockets.

Of those selected here, we have first chosen an option of the Tonor brand that includes two handheld microphones that offers optimal sound quality at a price, if not the most economical, yes reasonable.

What Is A Wireless Microphone?

In general, a microphone collects sound waves and transforms them into electrical signals. In a conventional one these electrical signals are transmitted through the cable to the sound system.

In the case of wireless, the microphone is mounted on a radio frequency transmitter that emits radio waves, and these, in turn, are received in a receiving element that is connected to the equipment.

How A Wireless Microphone Works

To work you need a receiver for each transmitter and that the two components are synchronized in the same radio frequency.

In the event that more than one is used at a time, each sender-receiver assembly has to operate on different radio frequencies in order to avoid interference between them.

Transmitter-Receiver Binomial

  • Transmitter: It converts the microphone audio signal into a radio frequency signal and broadcasts it on the air.

There are two main classes of transmitter:

The handheld: Integrate the microphone and radio-emitting device into the microphone grip tube.

The one with a pouch: It allows you to connect different sound sources and convert them into wireless either a head microphone, flap, instrument or the cable, for example, of a guitar to make it wireless.

  • Receptor: It connects to the input of the microphone and captures the radio signal emitted by the transmitter to transform it into an electrical signal.

There are several types: the fixed call that connects to the network, batteries and another option known as diversity with two antennas to operate the most powerful at all times and ensure better signal reception.

Advantages And Disadvantages Of A Wireless Microphone

Obviously, the most outstanding advantage of wireless is comfort. Avoiding worries and risks about cables is essential in these models especially when acting on a stage and more if you have to move a lot.

Among the drawbacks we point out the two most outstanding:

  • At the same sound quality they are much more expensive than cable ones.
  • They are exposed to interference, although much has been improved.

What Types Are There

We distinguish the following:

Handheld: With built-in transmitter. It is best suited to sing or pass it from one person to another in an act.

Being the transmitter integrated into the body only has this component and the receiver. In general, the most prominent brands offer wireless versions of their cable micros to take advantage of the sound it offers.

Headband: It can also be attached to the ear. It connects to a body transmitter that the user carries attached in addition to its corresponding receiver.

Instruments: Depending on whether it is for metal, wind, string or percussion it will adapt in one way or another to the instrument.

The fundamental difference with the previous one for technical purposes is that it is designed to optimize the sound of an instrument and not that of the voice.

In the case of guitars or basses it only has two components: the pouch transmitter in which the instrument is connected and the wireless receiver.

How To Use A Wireless Microphone

Regardless of the convenience of reading the manual of the model that is acquired, we provide some wireless microphones generic considerations:

  • Turn on the receiver with the transmitter off. Most wireless receivers have automatic frequency selection and therefore it will be enough to press the button to be assigned.
  • Once the receiver has chosen a frequency most wireless transmitters have a button that will synchronize it with the receiver you just turned on. As in the previous case, it will be enough to press this button and the transmitter will connect with the receiver you have just configured and will be ready.
  • Signal levels in the transmitter and receiver must be checked to ensure a distortion-free signal.

What To Consider Before Buying A Wireless Microphone

We point out some of the most valued qualities:

  • Utility.
  • Resistance and robustness.
  • That it is comfortable and easy to hold while using (as is obvious we refer in this case to the handheld).
  • Good resistance to feedback (avoid couplings).
