Before my career as an audio technician, it was magic to me that by speaking into a microphone, my voice could be recreated at a much louder level through a loudspeaker. The technical reasons why would come to me years later. It all starts with the audio signal created by the microphone. So what is…
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…
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…
So you’re speaking into a microphone, but your hands are busy doing something else. Whether you’re at a podium, on a stage, or in the studio, placing a microphone on a microphone stand will significantly improve our freedom to do other things while using the microphone, whether playing guitar, flipping pages from a script, or…
Getting electric shocks unexpectedly is no fun at all, especially not when it has to do with working (or playing) with microphones. As a guitarist, I’ve experienced electrical shocks in multiple venues when touching the mic and guitar strings at the same time. These shocks could potentially be lethal, so I’ve researched the topic and…
Recently, I was setting up a public address system for a presentation and was thinking about the importance of microphone gain. I decided I’d research a bit to improve my knowledge of gain and share the details with you all! So what is microphone gain, and how does it affect mic signals? Microphone gain increases the…
As of late, I’ve been working regular live sound gigs requiring wireless microphones. It’s relatively easy to set up wireless systems and have them work properly. However, I thought I’d do some research into how wireless microphone systems work in detail. So how do wireless microphones work? Wireless mics send their output signals wirelessly via their…
Microphones are everywhere in our lives: at music concerts and live speaking events, in our phones, computers, and intercom systems. They’ve been called microphones for a long time. As silly a question as it may be, I figured I’d explain why in this article! So why are microphones called microphones? The term ‘microphone’ can be…
Whether you’re a seasoned audio professional, a newcomer, or an extra body on a film set, you may be tasked with operating the boom pole and microphone. Boom mics are excellent for capturing sound for video without being included in the frame. Holding a boom pole properly will maximize the effectiveness of a boom microphone and…
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…
Perhaps you’ve noticed some microphones come with switchable options: On/off switches; high-pass filters and other equalization boosts/cuts; polar pattern switches; and attenuation pads. Let’s focus on attenuation pads and how they work inside a microphone. So what is a microphone attenuation pad? A “PAD” stands for Passive Attenuation Device. The circuitry in active mics may…
Ribbon microphones, generally speaking, are the most natural-sounding microphones on the market. The precise transient response, amazing low-end response, and natural roll-off of high frequencies mean ribbon microphones “hear” very similar to how human ears hear. These microphones are expensive and fragile, so caution should be taken with anything that may damage them, including phantom…
