Audio Questions (Microphones, pickup patterns, etc.)
What type of microphone element can I use in the KLOVER MiK parabolic microphone?
Please see the Frequently Asked Questions tab at the bottom of the individual product page.
We do, however, have a few general guidelines:
- We suggest using a water resistant microphone, such as the Countryman B3, if your parabolic mic will be used outdoors.
- Lapel microphones typically tend to be “bright” or slightly biased toward high frequencies. If weight is not an issue a small diaphragm condenser (pencil) microphone will usually provide a flatter audio curve.
- The higher quality microphone element that you use, the better the audio quality from the parabolic will be.
- Microphones with a higher sensitivity will provide greater range.
- Using a microphone with very little internal, electronic noise (self noise) is highly recommended.
Does the KLOVER MiK parabolic microphones come with a microphone element or do I need to supply my own?
I’m not getting any signal from the parabolic microphone. What do I do?
If you are using a microphone with a 3.5mm TRS connector, check if the microphone requires “plug-in power”. If your microphone requires “plug-in power”, verify that the device you are plugging your microphone into is providing the required “plug-in power” voltage (usually between 3 and 10 volts).
What is the real range of the KLOVER MiK?
Another factor that has to be considered is the “signal-to-noise ratio.” In other words, how loud is the audio source that you want to capture in comparison to the ambient noise that you don’t want to capture. A parabolic microphone will amplify all sound energy (of equal frequencies) by the same factor. So you may be able capture a conversation from 500 feet in a nearly silent environment but it won’t be possible if the conversation is taking place next to a highway. The parabolic will not be able to separate the sound of the human voices from the road noise.
With all those factors being considered, we have captured conversation from more than 500 feet in quiet situations (relatively empty football stadium) using our 26-inch parabolic. In similar situations, we have captured conversations from more than 250 feet with our 16-inch parabolic. In the quite environment of a wedding service we have had customer’s capture wedding vows from 50 feet. If you are interested in capturing high frequency sounds such as bird noises, the range will be even greater.
What does the pickup pattern look like for your parabolic microphones?
Please refer to our test curves under the “Test Results” tab at the bottom of the individual product pages.
Can I hear someone speak who is not facing the parabolic microphone?
While the maximum sound energy is available when the speaker is facing the parabolic collector, sound energy (pressure waves) radiate out from the side of the speaker’s head as well as directly forward. In addition, the sound energy is often reflected off a nearby person or object toward the parabolic.
Don’t parabolic microphones make the audio sound “tinny”?
Lower frequencies are absorbed more than higher frequencies. That is a fact that cannot be ignored. However, the loss of low end response for parabolic mics is not nearly as bad as some would have you believe. We have a short video that was shot during the setup of an outdoor music event. The low frequencies of the music (being used to setup the audio system) was picked up quite well by a 9-inch parabolic.
In addition, nearly every mixing board and video editing software package will allow you to add base and reduce high end frequencies to equalize the audio input from the parabolic mic to suit your taste.
Most audio experts, including people we respect very highly, would tell you that a 9-inch parabolic will not capture (amplify) any audio below 2,000 or 3,000 Hertz. The white papers and formulas that we have found in our research would confirm this belief. However, if this were true very little of the human voice would be picked up by a 9-inch parabolic and the low frequencies of a bass would certainly be below this threshold. Our second sample video demonstrates that this is not the case, as it shows how well the small parabolic mic captured the low frequency sounds generated by WWII aircraft.
Our theory is that most of the research on parabolic reflectors is relying on the properties of electromagnetic waves, particularly the wavelength of those waves. These types of waves are applicable to satellite dishes or antennas but not to audio. A parabolic microphone is capturing pressure waves, not electromagnetic waves so the wavelength is not relevant in the same way as it is to electromagnetic (radio) waves.
As mentioned above, we cannot ignore the way that different frequencies react differently when reflecting off a surface. Parabolic collectors (microphones) do a better job of amplifying higher frequencies that lower frequencies. In order to provide a more natural sound we have joined forces with Countryman Associates to create a microphone that is specifically equalized to match the acoustic characteristics of the KLOVER MiK 09 parabolic collector. The equalization also works extremely well with the KLOVER MiK 16, giving each a flatter, more natural sound then when used with a standard lavaliere microphone element.

Application Questions (Usage, etc.)
Can I use a parabolic mic to record music?
We do not recommend using a parabolic microphone for recording music. As mentioned throughout our website, parabolic microphones do have a bias toward high frequencies so the music will not sound “pure.”
Can I use a parabolic microphone with a P.A. (sound reinforcement / public address) system?
Yes and No. Because parabolic microphones are so sensitive, feedback is a huge challenge. Great care must be taken with the location of the parabolic mic relative to the speaker.
When possible mounting the parabolic at an angle to any flat surfaces, such as walls, will help to reduce this feedback.
Can I listen through walls or windows with a parabolic mic?
No. In spite of what you may have seen on television, or in the movies, that’s just not possible. You must have a more-or-less clear path between your subject and the parabolic in order to capture the sound energy.
Can I use a parabolic mic to listen to my neighbors?
Yes, and No. While our parabolic microphones will probably capture audio from your neighbor’s yard, you will be taking a huge legal risk if you do so. If you record a private conversation, you are in danger of being accused of not only eavesdropping on the conversation, but wiretapping as well. Our parabolic mics are intended for broadcast, sound reinforcement, and law enforcement / security applications.
