In this installment of our blog series on Basic Audio Techniques for Video we’ll how to properly use the tie bar when miking talent. If you missed the previous installment explaining how to choose handheld microphones you can read it here.
Lavalier microphones are used for a variety of television, theater, and public speaking applications. In order to capture clear audio, it’s imperative that you properly rig the microphone on your talent. Read on as we explore how to use the tie bar and explain how to form the proper Newsman’s Loop.
Proper Set Etiquette
Tie bars an efficient way to rig someone in situations where it’s appropriate for microphones to be visible to the audience. However, it’s important to follow proper set etiquette when working hands on with talent. Rigging mics, cables, and transmitter body packs requires a degree of intrusion into boundaries of privacy and personal space. For some of the people that you may be working with on-camera, getting miked may be a new experience. To put the talent at ease, always present yourself as professional and tidy. Make sure to introduce yourself and ask permission before attaching the microphone. If the talent is hesitant, you can enlist the help of a crew member of the opposite sex. When working with minors, ensure a chaperone is present at all times.Preparing the Lavalier
Rigging the Microphone
Take a moment to assess the situation before approaching the talent. Based on the specific scene at hand, determine where it is best to mount the microphone. There are a few basic choices, including: a lapel or center chest, which is best when the talent is wearing a tie, button down shirt, or blouse. When working with female talent, it’s important to note that women’s blouses open from the opposite side as men’s shirts. This means you’ll be required to flip the tie bar before clipping it onto the talent.![Rigging the Microphone](https://audio-technica.com/wordpress/app/uploads/Screen-Shot-2017-02-13-at-4.32.17-PM.png)

Newsman’s Loop
Much like vibrations carry along a guitar string, handling noise will carry along the microphone cable. The tie bar can be used to combat cable vibrations through a technique known as “The Newsman’s Loop.” Once the microphone is inserted into the spring clip, bring the cable around and up through the hinge of the tie bar, forming a “J.” Then, attach the jaws of the tie bar to wardrobe and continue the loop behind the clothing. The final and most important step is to secure the loop by closing the teeth of the tie bar on the cable. This will not puncture the cable; it was designed to work this way.![Newsman’s Loop](https://audio-technica.com/wordpress/app/uploads/Screen-Shot-2017-02-13-at-4.33.54-PM.png)
Wire Basics
The thin wires that connect the microphone capsule to the lavalier’s power module are not as strong as heavy-duty XLR cables. Therefore, they should not be used as extension cables.![Wire Basics](https://audio-technica.com/wordpress/app/uploads/Screen-Shot-2017-02-13-at-4.34.07-PM.png)

Inverted Rigging
Sometimes you may notice someone on television wearing what appears to be an upside down lavalier. This is no mistake; it’s purposely done to reduce popping caused by wind noise. If your talent faces downward frequently or exhales heavily, then soft puffs of wind may strike the microphone diaphragm. One solution is to use a windscreen, though these can be easily lost and often rub against clothing, creating additional unwanted noise.![Inverted Rigging](https://audio-technica.com/wordpress/app/uploads/Screen-Shot-2017-02-13-at-4.35.07-PM.png)
