How Do I Place My Condenser Mic for Best Sound?
Table of Contents
A condenser mic is an extremely sensitive recording device because it is built to pick up detailed sounds. When placed correctly, a condenser mic can give you the clearest and most detailed sound recording. However, if you fail to position condenser microphones in an optimal placement, then they can easily record unwanted noises that can ruin your recording.
To ensure that your final recording is to your liking and that you spend the least amount of time equalizing and editing, it’s important to know the best placements for your condenser mic. This will also help you maximize your condenser microphone and give you the best overall sound possible.
How Does a Condenser Mic Work?
Similar to how other microphones work, condenser mics convert sound waves into audio signals. However, condenser mics differ from other microphones because the sound waves are pressed against their diaphragm in order to produce the audio signal.
The diaphragm moves in accordance with the sound pressure difference between the front side and the backside. Once the sound waves hit the diaphragm, the diaphragm will vibrate in close proximity to the backplate.
The condenser mic must, of course, be plugged into an external power source, either phantom power or a battery depending on the model. However, there are condenser mic models that can be powered using external PSUs and T-power, but it is recommended to still use phantom power as the condenser capsule requires a high impedance converter.
Best Placements for Condenser Microphones
For you to maximize your microphone and get the best sound quality for your recording possible, knowing the right placement is of utmost importance. Half the work of producing a professional and superior sound quality recording is figuring out the optimal position for your microphone.
With condenser microphones being highly sensitive, how and where you place them can directly affect the quality of your audio recording. By applying some of these placement tips, you can maximize the use of your condenser mic and more.
Proximity Effect in Proportion to Placement
A proximity effect happens when the microphone is too close to the sound source, which leads to an increased bass response or low-frequency sound. This usually happens in directional and bidirectional mics.
If you want a more natural-sounding recording, then it is important to take note of the proximity effect. This will also help you avoid getting a muddy sound recording, especially if you are close-miking an amplifier or instrument.
The sweet spot of a condenser microphone is to place the sound source 6 to 8 inches away from the diaphragm, may this be an instrument, amplifier, or yourself. You can also position the microphone slightly off center, right, or left just to avoid plosives.
Be Mindful of the Microphone’s Directionality
Depending on the model of your condenser microphone, the polar pattern may differ. It is crucial to know the polar pattern your microphone has as it will determine the directionality of how it will pick up sounds and where it can be best placed.
A condenser mic has a side address, which means the on-axis response line is at the side and will be most sensitive to said direction. The side address of a condenser mic goes hand-in-hand with the polar pattern of your microphone model. If your condenser mic is omnidirectional, then it is sensitive from all angles so it’s best to position it at the center where it can equally pick up sounds.
A bidirectional microphone has a figure-8 polar pattern, making it sensitive from the front and back while it won’t be able to pick up any sound from the sides. Lastly, a unidirectional microphone is sensitive from the front so it’s best to point it towards the sound source for a clear recording.
Tilt Your Microphone
Tilting is a common mic placement tip for vocal recordings since it helps avoid plosives. Tilt the condenser mic slightly backward to block out the air from directly hitting the diaphragm while still picking up the audio from the sound source.
For added protection on plosives and unwanted noise being picked up, you may also opt to purchase a pop filter if your condenser mic doesn’t already come with one.
Final Note
To maximize and get the best sound quality possible in your audio and sound recordings, knowing the optimal placement for your condenser microphone is important. If you place your condenser mic properly, you may even cut down the studio editing time needed for cleaning up the recording.
