Poor sound can often derail even the most visually stunning video production. Whether in studio, conducting an ENG interview or staging events, one of the biggest keys to great audio is choosing the right lavalier microphone for the job, knowing how to use it and investing in some handy helpers to keep your talent comfortable while also concealing it.
Lavalier Microphones: Small, Discreet, and Close to the Source
Lavalier mics (or “lavs”) are tiny microphones that clip onto a subject’s clothing, usually near the chest. Because they’re worn on the body, they’re great for capturing consistent, close-range audio, even when your talent moves around. This makes them ideal for interviews, documentary work, and any situation where mobility or visibility is a concern.
When to Use a Lav:
- News & Live Studio Production
- One-on-One Interviews
- Talking Head Videos
- Live Events
- Dialogue where the subject is constantly moving
Pickup Patterns – Polarity Matters
One of the most critical aspects to consider when choosing a lavalier mic is its pickup pattern, or polar pattern, which determines how the microphone responds to sound from different directions. The most common patterns for lav mics are omnidirectional and cardioid (or directional). Choosing the right polar pattern depends largely on the recording environment and the movement of the talent. Understanding these characteristics helps ensure clear, professional-quality audio in any production.
Omnidirectional lavaliers capture sound equally from all directions. This makes them ideal for situations where consistent audio pickup is needed regardless of head movement – such as in documentaries, talk shows, or corporate videos. They’re also less susceptible to handling noise and clothing rustle, since they don’t rely on precise mic placement. However, because they pick up ambient sound as well as the speaker’s voice, they’re not always the best choice in noisy environments.
Cardioid, or directional lavaliers, are designed to pick up sound primarily from the front of the mic. This makes them well-suited for use in louder environments or when the speaker is in close proximity to other noise sources. However, they require careful placement – typically mounted pointing toward the speaker’s mouth and often hidden under clothing using a mic windscreen to reduce rustling noise. These mics are great for theatrical performances or field production where background isolation is key.
Lavalier Mics for the Modern Production World
Unlike traditional lavaliers that clip to clothing, Point Source audio has created a mic that mounts securely around the ear, placing the capsule in a consistent position close to the speaker’s mouth. This offers improved audio clarity and eliminates issues like fabric rustle, shifting placement, or inconsistent volume caused by head movement. Their “embrace” series, for example, offers customizable bendable frames for a perfect fit and they are available in skin tone colors to blend naturally with the talent. Now that’s pretty cool!
Lav Placement Tips
Placement matters more than most realize. Ideally, the lav should be 6-8 inches below the subject’s mouth. Attach it securely, avoiding clothing rustle. Hiding lavs under clothing can look clean, but be aware of fabric interference and use small windscreens to reduce noise.
For wireless lavaliers, it’s important to secure the transmitter pack to the subject’s waistband or pocket and leave some slack in the cable to avoid any strain or pulling. A smart accessory to consider is a Viviana Strap. These innovative straps allow you to comfortably mount wireless transmitters to the ankle, thigh, waist, or arm, giving your talent greater freedom of movement while keeping the pack securely in place. Always monitor for clothing rub or interference – and always do a sound check before going live or a final take.
The Lav Magnet – Mount Your Lav on Any Garment or Accessory
Sometimes the simplest solutions leave you wondering, “Why didn’t I think of that?” That’s exactly the case with the Lav Magnet. Designed to work with any wardrobe, it offers a reliable and versatile way to mic your talent. The system uses a two-piece magnetic design to secure your lavalier microphone in place, while the integrated clip holder keeps your mic positioned exactly where you need it – no matter the fabric or outfit.
