What microphone to buy? 4 Types of microphones

It is difficult to go buy a microphone when we do not have much idea of ​​how the sound world is going. In our stores we meet customers of all kinds, those who know a lot and those who don’t. If you are in the second group, after reading this you will be ready to make your first audio purchase .

First of all:

What is a microphone?

The microphone is an electrical acoustic transducer, that is, it transforms the acoustic signal of our voice into the electrical signal that the equipment to which it is connected reproduces.

The microphones can be classified according to different criteria, today we are going to clarify them according to their method of transduction:   dynamic microphones, ribbon microphones, condenser microphones, electret microphones.

 1. Dynamic microphones

 What are they used for?  

They can be used for any type of transmission: radio, television, conferences, concerts and even to record in certain situations (since, generally, the suitable microphones for recording are condenser), but a very good option for recording instruments is the microphone Dynamic  MB2K  by Audio-technica.

Advantages of dynamic microphones:

-The dynamic microphone is the most suitable for live voice since, as a general rule, by giving an irregular response it offers  more color and body to the voice of the interpreter.

-Its robustness

– Their price (they are relatively cheap)

-Your autonomy ( do not need power )

-They have protection against external magnetic fields

-Resist humidity, temperature and vibrations well

Disadvantages of dynamic microphones:

-The dynamic microphone has a fairly good sensitivity (40Hz to 16kHz), although lower than that provided by a condenser microphone (which we will explain below).

-It is not advisable to use it when we work with high frequencies (harps, violins …) and yes when it comes to low frequencies: voice, drums, amplifiers.

-Finally, we must bear in mind that the sound we want to achieve depends not only on the microphone we use but also on the equipment we have.

 Dynamic Microphone  Recommendations

Audio-technica MB1K Microphone: The MB1K is a very cheap microphone, it is a very good option as a microphone for your first performances.

Audio-technica MB2K Microphone: Microphone designed to record or microphone instruments such as guitars, violins, drums, amplifiers, etc.

DYNAMIC MICROPHONE SHURE SHSV100: This is a high performance microphone at a very economical price with high quality components to obtain the desired sound response.

Sennheiser E835 Microphone: A high quality microphone, designed for use in demanding environments where we need a totally perfect sound response. Concerts, rehearsals, conferences, auditoriums …

2. Condenser microphones

What are they used for?
Mainly, but not always, condenser microphones are used to make studio recordings: vocals, instruments, dubbing …

Advantages of condenser microphones
They have much more sensitivity than dynamic microphones and a flatter response at high frequencies. They are commonly used in recording studios as they very precisely collect any sound that will be played later.

Disadvantages
Due to its high sensitivity, it not only picks up the sound that is closest to you, but if we do not record in an adapted environment, any other sound can be filtered through, even if it sounds far away.

Condenser Microphone Recommendations

AT2020 Cardiode Condenser Microphone: This is a microphone with great value for money. The best that is on the market right now. This microphone will give you a great response when creating your first home studio.

Audio-technica AT2035 condenser microphone: Superior model to the AT2020. It stands out that it comes with an anti vibration mount and with decibel control, which will ensure that we can make the best recording.


3. Ribbon microphones

They are the typical microphones of the 50s, mythical are the images of Elvis. They were also used on the radio, the army …

Regarding their directivity, the ribbon mics are generally bidirectional, although there are some unidirectional models.

They are large and delicate microphones, and their frequency response is warm , since their response in high frequencies is usually quite poor, therefore, all ribbon microphones incorporate a small transformer to raise the low output voltage that are able to give and to adapt the low output impedance.

4. Electret microphones

Necktie microphones are very common .

What are they used for?
They are small microphones, the most common is to use it at events as a tie, to make small recordings or to microphone instruments such as: saxophones, transverse flutes, bagpipes.
