As a freelance sound engineer, I've spent a considerable portion of my time specializing in hiding microphones on performers for theatrical productions and broadcast events. I'm fortunate to work in a wide variety of venues across England and beyond, helping stage plays, opera, children's TV shows and films. 

Microphone placement for broadcast and theater presents a unique set of challenges compared to miking a concert or studio recording session. The ideal microphone position for sound quality is not always practical. More often than not, the microphone needs to remain as discreet as possible, so it doesn't distract from the performer or the audience's experience.  

Before securing a body-worn microphone to a performer, there are several important factors to consider. Every theatre mic placement is a compromise between sound quality, consistency, comfort, and concealment. The goal is to ensure the microphone delivers a reliable, natural response throughout every performance and across the entire run of a production.

In this article, I'll share the microphone placement techniques I use when miking performers for vocal reinforcement and recording in live theater environments.

Key Factors That Influence Theatre Mic Placement

Before choosing a microphone placement technique, it's important to understand the demands of the production and the performer. The right microphone position depends on far more than sound quality alone.

Here are some of the initial questions I ask when setting up a show:

• What is the performer doing?
• What is the overall show? Are we working a rock 'n' roll show or an Edwardian period piece?
• What is the design aesthetic?

You might work with the same performers across multiple scenarios, but they'll likely be giving very different performances. Subsequently, the way we use the microphones will be very different, too. A boom mic is perfectly acceptable aesthetically (and very much required) if you're working on a show that features an on-stage band. However, if your show is a period play that requires only subtle vocal reinforcement, you won't want to have a boom mic across the face of every actor.

Consider the Performer's Appearance 

Production details other than your desired sound will influence your microphone choice fairly early on. For example:

• What are they wearing?
• Do they have wigs, hats, masks, or crazy amounts of hair gel? 

All of these elements (and more) will have an impact on mic placement and at what point during the show prep you can fit mics to the performer. 

It's a good idea to meet with the costume designer as early as possible so that microphone placement, transmitter size, and wardrobe considerations can be discussed before rehearsals begin. If particular scenes could be a problem for a larger transmitter, the earlier you know, the better – especially if there are budgetary implications

Consider the Performer's Movement

Physical performance can be just as important as costume design when selecting a microphone position.

• How physical is their performance?
• Are they ruffling their hair?
• Rolling around the stage? 

You must consider the physicality of each performance when attaching both the microphone and the transmitter. Crucially, you have to take into account if the mic and body pack will stay put throughout a particularly physical performance. 

Communication Matters 

I firmly believe that good communication is key to a successful, smooth-running show. While wireless mics are only one part of the sound designer's palette of tools, they affect many other departments.  

On a standard day, I will talk to makeup, wardrobe, wigs, performers, stage management, and the sound department to ensure the job gets done.

Consistency is King

With some initial planning questions answered, it's time to put that information into practice.

For this example, let's assume the performance is not one that requires a boom mic. Instead, the goal is subtle vocal reinforcement that sounds natural and unobtrusive to the audience. 

Body worn mic placement almost always involves some compromise. Multiple departments are involved in the process, and the ideal microphone position from a sound perspective may not always be possible. Because of this, consistency has become one of the most important microphone placement techniques in theatre.  

If a microphone is positioned the same way every night, EQ, gain, and overall sound quality will remain more consistent throughout a production. 

A centimeter either way in wireless mic terms is a massive difference and can ruin an entire scene. Equally, poor securing of the mic will cause nightmares, too.  

I worked on My Fair Lady many years ago in the West End. One night, an understudy went on at short notice, leaving little time to double check placement and ensure a secure fit. 

Not only did the engineer have to deal with the performer change, but the ear hanger he was wearing flew off during the big dance number. The understudy tried to replace it, but every head flick sent it flying — not fun to mix and not fun for the performer. 

Why Consistent Microphone Placement Matters 

• Maintains consistent sound quality
• Helps preserve EQ settings
• Reduces gain adjustments
• Minimizes distractions during performances
• Improves reliability from show to show 

Choosing the Right Microphone Placement

Overall, I prefer placing microphones on the performer's head, between the temples just forward of the hairline. This position allows the mic to sit on the bone; in my experience, this improves the bass response and creates a fuller, more natural sound.  

I avoid securing microphones directly onto the face with tape. While there may be situations where this improves placement, it is often too uncomfortable for performers to justify the potential benefit. 

I tend to secure lavalier microphones to the performer's hair using clips. I secure the clips with milliner's elastic as this gives you some flexibility to move clips as required. Clips are available in several colors, or they can be painted to better match different hair types.

I would recommend matte spray paint rather than gloss finishes, as it doesn't glisten under the lights. I often use a pale clip and then color over the top with stripes of color to match hair types – like a zebra hiding from a lion! I use pens to do this as they're easier to control, but you might have to redo your work every so often. 

Typically, I'll use three clips:  

• One to secure the mic head and keep it pointing where you want it
• One to reinforce this position
• One to keep the cable tidy at the back of the head 

Step-by-step Placement Process

First, I create a parting to help the mic sit flat in the hair.

Then I use a toupee clip to secure the mic head (you want the mic to be pointing at the mouth of the performer).

The second clip acts as a reinforcement of this first position, anchoring the mic and securing the position. If you get this one wrong the mic will never sit in the right place.

The third clip sits at the nape of the neck just under that little lump where the skull meets the spine. You can secure it with a tape of your choice, but it's not always necessary – especially if you have a collar and the performance is not particularly physical.

Clips are a reliable solution when a microphone needs to remain in a fixed position throughout a performance, but they do require sufficient hair to stay secure. When a performer has very little hair, alternative microphone placement techniques may be required.

In these situations, it's still best to attach the mic to the performer's head for two reasons:

• The distance between the mic and the mouth stays consistent (which is good news for your front of house engineer!)
• Head-worn microphones are typically less susceptible to noise, movement, and accidental repositioning than shirt-mounted microphone 

If your performer's hair or costume eliminates our preferred position between the temples, you can try moving the clips down towards the ear. If this lower position doesn't work, you could also try an ear hanger. 

Using Ear Hangers

Ear hangers pose a few known challenges, for which manufacturers have helpfully devised solutions in the form of frequency boost caps.  

As the microphone moves away from the hard bone of the temples, you will start to hear changes in the mic's frequency response. The "color" of the mic changes and we start to pick up muddy, muffled tones; you can counteract this with desk EQ, or by using caps to boost the top end. 

You can buy ready-made ear hangers, but I like to make my own. Here's how:

If you take a hairpin and straighten it out, you can cover it in your chosen way to make it comfortable for your performer. I like to use Luko Tape by 3M. I cut a strip that is equal to the length of the hairpin and wrap the tape around the pin.  

Next, I make a bend in the pin; this will secure the front of the ear hanger to place it on the performer and follow the shape of the back of their ear.  

Finally, snip off any excess with side cutters (or strong scissors), and you've got yourself an ear hanger. 

The main advantage of this approach is that performers can adjust the shape to fit their ear comfortably while remaining confident that it will stay securely in place without relying on tape or glue. 

Transmitter Placement

With the microphone securely placed, it's time to start thinking about your next challenge — the transmitter.

Standard Transmitter Placement

For most performances, the transmitter can sit comfortably in a pouch on the waist. To secure it, I typically use a two-inch wide elastic band secured at the front with velcro. The elastic band will sit quite happily under the clothes, providing the performer doesn't fall on it or apply pressure directly.

Creative Solutions for Challenging Costumes

I often get asked about naked performers. There's quite a lot you can do in these situations, surprisingly! Hiding the transmitter on the head is a fantastic solution, but it does require some trial and error. 

As transmitter sizes have decreased over the years, these types of solutions have become much easier to implement. In the early 2000s, we managed to hide a transmitter on a completely naked performer for a single scene by creating a pouch in the performer's hair. Just last month, we employed the same tactics for an opera performer – the transmitter was so light and comfortable that he wore it on his head for the whole act! 

Here you can see the mic pouch being sewn into a strap, covered by a stock wig that the wigs department found. It matched our performer exactly!

The pouch was clipped into the performer's hair and secured on either side of the head using wig elastic and toupee clips.

In the example above, the final clips aren't sewn into place, but the transmitter is sitting quite happily at the nape of the neck. When constructing a transmitter pouch, it's important that everyone involved understands the final dimensions of the transmitter, including the aerial and microphone connectors. In this case, we had to tape the aerial down to prevent it from becoming visible.

It was entirely invisible once correctly fitted thanks to some amazing team work in action; a willing performer and a wig department completely up for giving it a go, plus some handy sewing skills from the sound department.

If we tried to use a plain black pouch, we wouldn't have enough hair to cover the transmitter. By adding a little camouflage, we were able to create a comfortable solution without having to resort to hiding the mic cable down his spine using lots of tape and makeup. 

Improvements in equipment design continue to make it easier to conceal transmitters and body-worn microphones in theatre productions. 

The Bottom Line: Communication Matters

If you only take one thing away from this article, it should be that clear communication is essential. Successful theatre microphone placement depends on more than just the sound department. Wigs, wardrobes, performers, makeup, stage management, and lighting can all influence where and how a microphone is placed. 

For example, I recently worked on a show with a false ceiling. As a result, all the lighting came from the sides, which meant that any exposed neck cables had to be securely taped down, so as not to catch the light. By communicating openly with the lighting department, we were able to identify the issue early and address it before it became a problem during rehearsals or performances. 

The earlier you involve other departments, the easier microphone placement decisions become. Even a quick conversation can uncover practical considerations that affect costumes, performer movement, visibility, or sound quality.

I also find it helpful to learn how other departments work and understand the challenges they're trying to solve. Better communication leads to fewer surprises, smoother productions, and a better experience for everyone involved.

FAQ: Theatre Microphone Placement

Where is the best place to position a microphone for theatre performances? There is no single placement that works for every production, but head-worn microphone placement is often preferred because it helps maintain a consistent distance from the performer's mouth and can provide more reliable results throughout a performance.

How do costumes and wigs affect microphone placement? Costumes, wigs, hats, masks, and other design elements can all influence where a microphone can be placed. That's why microphone placement decisions are often made in collaboration with costume, makeup, and wigs departments.

What should I consider when placing a transmitter? Comfort, concealment, and security are all important. While waist-mounted transmitters are common, some productions may require more creative placement solutions depending on the costume and staging requirements.

Why is consistency important in theatre mic placement? Even small changes in microphone position can affect sound quality. Consistent placement helps ensure performers sound the same from show to show and makes it easier to maintain predictable audio settings throughout a production.

What's the most important tip for successful theatre microphone placement? Communication. Working closely with performers and other production departments can help identify potential challenges early and lead to more reliable microphone and transmitter placement throughout the run of a show.
