Microphones?


There are many different types of uses for a microphone; however, the key to making an instrument or voice sound good is knowing what type to use with each instrument you come across. According to Ear Trumpet Labs, the microphone that you use will affect the over all sound and feel of each instrument; thus, it will have a huge affect on how the audience perceives it in a live setting. The main qualities of a microphone that discern what you should pick for each instrument depend on if they are dynamic or a condenser microphone.

What’s the difference?

Dynamic Microphones are the most commonly used microphones in the live sound industry. They are used for a variety of instruments; however, they are mainly used for vocals, bass and guitar cabinets, drums, and other percussion instruments. They are the go to microphone for many traveling bands and sound engineers because they don’t require a power source and are very durable. Durability is key with microphones because, well, no matter what you do they will be dropped or soaked in water (ask me how I know…). Another factor that leads many sound engineers and bands to use these is their price point. They aren’t that expensive so getting extras or breaking one isn’t as detrimental as breaking one that is five times as much for a little better sound. Paul White explains that on of the few down falls to dynamic microphone is that the instrument or source of sound has to be relatively loud in order for the microphone to pick up the entire frequency range. Sometimes this doesn’t matter; however, if you are working with a instrument that is higher pitched, a lot of the higher pitches and detail will not be projected and picked up correctly. Dynamic microphones are great and can be used on a wide variety of instruments.

Condenser microphones are not as commonly used simply because of their price point; however, they are important to every sound engineer. Unlike the dynamic microphones, condenser microphones require power of some sort or what we sound engineers call it, “phantom power.” Phantom power is power that is sent from a mixer to the microphone and without it the microphone wouldn’t work. This poses a problem in some venues because not all mixers have the ability to send power to microphones this way. Condenser microphones are mainly used for choirs, pianos,  or as overheads on a drum set because of their pick up pattern is much wider and better than that of a dynamic microphone.  Condenser microphones have a much better frequency response than that of a dynamic microphone. This helps bring out  higher pitches and tones that some instruments produce as well as giving the microphone the ability to pick up much quieter instruments. Even though many sound engineers can get by with using only dynamic microphones; condenser microphones are a vital tool in perfecting a bands sound.

Overall, picking the right microphone for each source and application is very important. Stay tuned for future tips and tricks for becoming a great live sound engineer.

  1. Nathaniel,


    Being a recording/performing musician who is starting his own home studio I must tell you that I love your post and blog. I just recently was talking to a friend of mine studying Music Production in Berklee College of Music about microphones and talking about what we were both using for our recordings. I remember when I was getting my Associates in Music/Music Education I took only recording and MIDI classes for electives and I remember studying about condensers, dynamics, ribbon microphones and all and I must say you did a good job in your post. I think it would be great to see some more posts about microphones, perhaps as a particular threat of posts with other posts talking about microphone techniques. The one ‘lesson’ I remember the most about my sounds recording classes, and we were discussing this with my friend I mentioned previously, is how there is usually a predetermined microphone that you want to use record a particular instrument, but at the end of the day all of these are more like guidelines than actual rules and sometimes you can get unexpectedly great sounds from trying a different set-up.

    Best of luck with your blog,

    Paolo Bettaglio
