What Are FETs & What Is Their Role In Microphone Design?

When looking through catalogues of condenser microphones, it’s fairly common to see the terms FET or solid-state used to describe the microphone. Many condensers on the market today have FETs or JFETs in their design. What are FETs & what is their role in microphone design? FETs (field-effect transistors) are active electrical devices that use…

What Are Microphone Transformers And What Is Their Role?

Some microphones have transformer-coupled outputs, while others are deemed transformerless. Some microphones even have transformers in the middle of their signal chains rather than at their outputs. What is a microphone transformer? A mic transformer is a passive electrical device that physically isolates two circuits while maintaining an electrical relationship between the circuits. Mic transformers…

Why Do Microphones Have Screens? (Pop Filter, Grille, Windscreen)

When looking at any microphone, we notice a screen covering the microphone diaphragm and capsule. This screen is typically a mic grille/cap mesh but can also be a windscreen and/or an additional pop screen/filter. Why do microphones have screens? Mics have screens (grilles/caps) to protect their sensitive diaphragms physically. Screens also protect against plosives (pop…

How Are Microphones Made? (Designs, Materials, Production)

Microphones are all around us: in our cellphones and laptops, at live music, broadcast, and presentation venues, and in the mic lockers of audio professionals. If you’ve ever wondered how all these microphones are made, this is the article for you! How are microphones made? Different microphone manufacturers produce their microphones differently. Some design and…

How Do Microphones Work? (The Ultimate Illustrated Guide)

It’s not often that we think about how microphones work. Microphones are part of our day-to-day lives and are somewhat taken for granted, so I’m glad you asked about how they function! How do microphones work? Microphones work as transducers, converting sound waves (mechanical wave energy) into audio signals (electrical energy). The microphone diaphragm vibrates…

Do All Microphones Have Transformers And Transistors? (+ Mic Examples)

In my deeper research into how microphones work, I found that transformers and transistors are key components in many microphones. Do all microphones have transformers? Although transformers are common in microphones, they are certainly not required. Nearly all passive ribbon and tube mics have output transformers. Many dynamic and condenser mics have transformers. Active ribbon…

What Is A Microphone Capsule? (Plus Top 3 Most Popular Capsules)

Of all the parts and designs that go into creating a microphone, the capsule is the most critical element. What is a microphone capsule? The mic capsule is the part responsible for the conversion of sound waves into mic signals. Capsules (or baffles when referring to ribbon mics) always feature diaphragm(s) and the housing for…

Microphone Types: The 2 Primary Transducer Types + 5 Subtypes

There are plenty of microphones in existence and many different types of microphones. When it comes to the way microphones transduce energy and create their audio signals, there are two primary types of microphones to choose from. What are the 2 primary microphone transducer types and their subtypes? Perhaps the broadest way to classify microphones…

What Are Microphone Grilles And Why Are They Important?

If you’ve ever spoken into a microphone before, you probably know to speak into the metal grille for the best results. Chanced are you’ve spoken into a handheld microphone with a spherical grille. Microphone grilles come in many shapes and sizes and have many purposes for microphone performance! So what is a microphone grille? A…

What Is A Microphone High-Pass Filter And Why Use One?

Some microphones come with switchable options, including various polar patterns, attenuation pads, and, as the title of this article suggests, high-pass filters! The microphone high-pass filter (HPF) proves to be a useful option for many microphone applications. Let’s talk about HPFs and how they relate to microphones. So what is a microphone high-pass filter, and…

What Is A Microphone Diaphragm? (An In-Depth Guide)

Diaphragms have a lot to do with sound. We “sing from the diaphragm” of our physical bodies, and if we’re singing into a microphone, we’re interacting with a diaphragm as well! Every practical microphone has a diaphragm, and an understanding of diaphragms is crucial for microphone mastery. So what is a microphone diaphragm? A microphone…
