Cardioid Mic

With the development of sound reproduction industry came the development of various types of microphones. The type of microphone depends entirely on the use and purpose of the same. Microphones are mainly split into two categories: omni-directional and unidirectional. As the name suggests, omni-directional microphones can pick up sounds equally, to an extent, from all directions. It does not matter from which direction, from the front, rear or sides, the sound is produced, omni-directional microphone will pick it up. Unidirectional microphones only register sound from one direction, hence the prefix uni, meaning one. When it comes to unidirectional microphones, cardioid microphones are perhaps the most popular.

These microphones are named cardioid because of the pattern of their sensitivity, which reproduced on an axis looks like a heart. Cardioid microphones have such range that their best place to pick up sound is when it comes from the front, i.e. when a speaker is speaking directly into the microphone, while the sound from the sides is registered a bit lower, with the sound from behind being picked up in small quantities or not at all. That is why cardioid microphones are best used for live performances, such as concerts, public presentations and in all other situations that require a vocal microphone.

The most known use for these microphones is perhaps in the telephone, as the microphone integrated in the handset only picks up speakers’ voice, eliminating the background noise as much as possible. Cardioid microphones are also used while recording in studio, for vocals and for some certain drum elements.

Whether you want to purchase a cardioid microphone because you want to record your broadcast or podcast, or you maybe want to purchase it for your live shows, it is always hard to find the one that suits you the best. Of course, the main factor when it comes to deciding which cardioid microphone you want to purchase is the budget. The more money you have, better options open up for you.

Best Buy Cardioid Mic – Shure BETA 58A (B0002BACB4)

Cardioid mic Shure BETA 58A (B0002BACB4)

It should not be strange that the runner-up on this list is a microphone from the famous Beta series by Shure which are adored by professionals. Beta 58A has all of the features and the looks of the original Beta and 58 series of microphones, but it is a step-up in the evolution of performance.

Pros:

With the polar patter being supercardioid, Beta 58A ensures that the side and rear noises are reduced to a bare minimum. This microphone is designed for close up vocals and it delivers that in every way possible, with frequency response of 50 Hz to 16 kHz. Although frequency response is not as big as it is with the SM7B, it is still good enough to come second to the best. The output level is a bit lower and the impedance is the same as in SM7B model, -51.5 dBV/Pa and 150 ohms respectively, therefore the performance and sound levels are very similar if not same in some instances. Some of the features of Beta 58A are the brightened midrange and bass rolloff that control the proximity effect, therefore this microphone is really tailored for vocals. The neodymium magnet is a great inclusion for signal-to-noise output. The advance pneumatic shock mount really prevents the transmission of mechanical noise and vibration, so if you want to be like Bruce Dickinson of Iron Maiden fame and jump all over the stage there is no fear that it will influence the sound transmission. Beta 58A has become a leading choice for touring artists and singers, which is not surprising as this microphone has all of the bells and whistles which are necessary for an extensive and long-term use. It is also a good choice for recording, as some engineers use it for acoustic guitars and vocals.

Cons:

The only drawback of the Beta 58A dynamic microphone has to be frequency response, which is lower than with the SM7B, but other than that it is an excellent piece of music equipment.

Beta 58A, along with SM58, is an industry standard which makes it probably the best choice to buy after the SM7B, because it comes near the performance that the best cardioid microphone has for a lower price. That is why it is safe to say that Shure Beta 58A is the bestbuy cardioid microphone out there.

Pros:

You cannot find a studio or a rehearsal room in the world that does not have at least one of these microphones. That is because of SM58 features and affordability. The price is definitely the biggest trait of this product, but it is also a reliable microphone that will take a lot of beating before you have to replace it. With some features that are almost the same as in Beta 58A, like the pneumatic shock-system and the frequency that is specifically made for vocals, SM58 also comes with surprising additions that make it a crowd favorite. These features include the built-in wind and pop filter, which is astonishingly efficient. Of course, that is not to say that you should not use additional protection when recording with this microphone, but it is perfect for live performances. With frequency response of 50 to 15 000 Hz and impedance of 150 ohms, this cardioid microphone gives out astonishing performance which no one would be ashamed of. This legendary microphone is not the best one out there when it comes to performance, but it is a constant performer indoors or outdoors. With a little bit of messing with equalizer you can make SM58 into a powerhouse that will satisfy singers and sound engineers alike. With very clean and pure sound SM58 definitely stands out from the crowd and gains a respectful place on our list.

Cons:

The frequency response of this microphone is not as high as in the Beta 58A or SM7B and it will not give out-of-box like performance that these two other microphones can provide, but with a little bit of skill and knowledge it can be turned into an excellent microphone.
