Lavalier Microphone Mounting Techniques

Lavalier microphones are attached differently depending on the nature of their use. For instance, in theater applications where the microphone is used to amplify an actor or a singer's voice, lavs are typically concealed in their hair. This eliminates the possibility of scratching against their clothing while they move, which would result in the amplification of the scratching sounds as well. It also adds to the suspension of disbelief, since the characters themselves would not be wearing microphones, especially if the plot is set in a time before lavalier microphones existed. Occasionally, specially-designed skin-color headsets known as "headworn microphones" are used in stage applications when actors spend a good deal of their performance singing and moving around quickly (such as in stage musicals and in lecture or presentation scenarios). A headworn microphone is essentially a lavalier on a stiff wire mount which loops over the talent's ear.

In television and documentary applications, the lavalier will typically be clipped to the subject's clothing, such as a tie, jacket or collar. In narrative motion picture usage, lavs are almost always hidden under clothing to conceal the fact that the person is mic'ed. The Boom microphone typically sounds 'better', more natural than a lavalier mic and is always a soundman's first choice, however oftentimes for exterior location shooting, it may be more practical to use a lavalier. One such situation would be during a wide shot that forces the boom operator to keep a distance with his microphone from the speaking talent that isn't close enough to achieve a good signal to noise ratio. In that instance a lav mic hidden on the talent due to its proximity can achieve good signal to noise ratio for recording of speech. When lavalier microphones need to be concealed under clothing, the possibility of material scratching against the microphone is a certain risk. To minimize this, sound recordists might wrap the head of the microphones in moleskin or place it inside a hollow centered column-shaped sponge and place it under a placard, behind a button, or within the knot of a tie. The transmitter pack which the microphone is attached to may also need to be hidden under a person's clothing. Transmitter pouches are held on with elastic straps and hold the transmitter in various places, hidden wherever the clothing provides a non revealing space, i.e. high around the waist in the space created at the spine just above the belt line, inside the thigh under a skirt or dress, about the ankles under a pant leg, or even on the inside of a boot.

Wireless Lavalier Microphone Buying Tips

Want to buy a wireless lavalier microphone? Here the great tips for you to get the best deal of wireless lavalier microphone in the market.

A microphone is an electronic device that convert sound into electrical energy and back into sound energy when it is transmitting out from the speakers. A wireless lavalier microphone is one tiny device that can be clipped onto your collar. It is usually linked to a wireless transmitter strapped to the belt or body. The transmitter will then link to the base wireless station.

This frees your hand and you will be able to use them for other purposes. They are commonly used by people giving presentations, bodyguards, backstage personnel and even professional singers giving a concert.

Here are some wireless lavalier microphone buying tips to consider while shopping for lavalier wireless microphone.

Frequency of Wireless Lavalier Microphone System

This is one important factor to consider before purchasing your microphone. This rule can be applied to other wireless products which you intend to purchase as well.

Ensure that the wireless system has a wide range of wireless frequency which you can switch to. If you are suffering from signal distortion, typically changing to another frequency will solve the problem. Hence, with a wide range of frequency channels, you will be able to solve your signal problem and indirectly increasing the wireless signal range of your wireless microphone.

Auto Scanning of Channels

If possible, purchase one wireless lavalier microphone system which is able to automatically scan for "un-congested" frequency channels. This will ensure that you are on the best frequency channel and will not be suffering from signal related issues.

Clarity of the Sound

Depending on your usage, this is another specification which you need to note before buying. If the system is used for a stage presentation, a microphone with small frequency range, 50Hz to 16kHz, is ample to allow the audience to hear the presenter's speech.

However, if you are using it for a concert or to sing a song, it is recommended to get an more expensive wireless lavaliere microphone which is able to support more frequency range such as 20Hz to 20kHz

Battery life of lavalier wireless microphone This is important if you are planning on using it for more than 2 hours. Common lavalier wireless microphone has a battery span of 2-3 hours. It is a common known fact that battery will lose their ability to store 100% of the charge rate over a period of time.

Hence, if you are going to use your microphone that you have kept for a long time in the warehouse, try using it on a full charge and check how long it took to become flat.

Certainly you do not wish to battery to be flat when you are giving an important presentation or while singing.

Another buying tip. Instead of buying those wireless lavalier microphone with 2-3 hours of lifespan, consider getting those which are able to last much longer at 7-10 hours per full charge. Although they are slightly more expensive, they could make or break the deal when you need it.

Simultaneous Connections to the System

If you are using for a presentation with a single speaker, a wireless system which has a single antenna to link to one wireless microphone is ample. However, if it involves an event like debate where several speakers will be speaking at the same time, the recommended guide line is to look for a wireless system which can handle 30% more simultaneous connections. This ensure that you are able to add in more connections for additional wireless microphone for speakers if needed.

Generally, buy one set of wireless lavalier microphone system which is customized for your needs. If you are using your sound system for demanding environments, be prepared to fork out money for quality product as they provide you with better sound quality, wider frequency response and more features.

Look for product specifications on-line and read the reviews of the buyers. From there, you will already have a clearer picture of how suitable the wireless lavalier sound system is suitable for you.

History of Lavalier Microphone

Know more about lavalier microphone, this is the history of lavalier microphone or lapel microphone.

The term lavalier originally referred to a pendant worn around the neck. Its use as the name of a type of microphone dates from the early 1960s.

An American electronics engineer with Educational Media Resources and San Jose State College, Raymond A. Litke, invented the wireless microphone in 1957 to meet the multimedia needs for television, radio, and classroom delivery. His U.S. Patent No. 3,134,074, filed May 6, 1961, (originally filed January 8, 1960) is for the first portable, workable, practical, and dependable wireless microphone. The patent's diagram illustrates a cigar-sized device which was six inches long and weighed seven ounces, including a power supply and transmitter. Impressed by the more than one-half-mile distance of transmission, the FCC granted Litke 12 frequencies at his approval hearing. Litke coined the term "lavalier microphone," a word which appears in his patent.

Also called the Vega-Mike, after Vega Electronics Corporation which first manufactured it in 1959, Litke's midget device (both hand-held and lavalier) was used by the broadcast media during the 1960 Democratic and Republican National Conventions. It allowed television reporters to roam the floor of the convention to interview participants where Presidential candidates Kennedy and Nixon were the first celebrities to use the wireless microphone. The American Broadcasting Corporation (ABC) completed testing in 1959, prior to the conventions. Television anchor John Daly was exuberant with his praises for Litke's invention on the television news in July 1960. The wireless microphone was also tested at the Olympic trials held at Stanford University in 1959.

In newspaper articles from both the San Jose News of September 10, 1960, and The Alma Signal-Enterprise (KS) dated November 10, 1960 and February 26, 1981, Litke attributes the inspiration of his invention to the winged communication of the bee. Although electronics experts and scientists told him the wireless microphone was an impossibility, Litke managed to invent the microphone in 1957. This wireless microphone was only one of Litke’s inventions. In the 1960s, Litke was employed at University of California Medical Center in San Francisco where he invented several medical instruments, including the fiber-optic colonoscope.

What is Lavalier Microphone

A lavalier microphone or lavalier (or lav or lapel mic) is a small electric or dynamic microphone used for television, theater, and public speaking applications, in order to allow hands-free operation. They are most commonly provided with small clips for attaching to collars, ties, or other clothing. The cord may be hidden by clothes and either run to a radio frequency transmitter in a pocket or clipped to a belt (for mobile work), or directly to the mixer (for stationary applications).

These miniature microphones are often supplied with a choice of push-on grilles of differing lengths that provide gentle high-frequency boost by forming a resonant cavity. A peak of approximately 6 dB at 6-8 kHz is considered beneficial for compensating loss of clarity when chest-mounted, and a peak of a few decibels at 10–15 kHz when mounted in the hair above the forehead. This method of boosting high frequencies does not worsen noise performance, as electronic equalization would do.
