What Is Body-Worn Wire Routing Concealment? (Mic Routing)
Body-worn wire routing, often called mic routing, is the safe placement and securing of a production microphone cable on the outside of a consenting wearer’s clothing. The aim is reliable sound without snagging, pinching, restricting movement, or interfering with protective equipment. No single route suits every person, garment, microphone, or work setting.
A quick win: before attaching anything, confirm the microphone and transmitter are compatible, then have the wearer move through the actions required for the recording. A cable that looks tidy while someone stands still may pull or catch when they bend, reach, or turn.
Here, “concealment” means orderly cable management for a production setup, not hiding recording equipment from someone or recording without informed consent. I treat consent, comfort, and safety as part of the installation, not as final checks.
What body-worn mic routing means
Body-worn mic routing is the path a microphone cable takes from the microphone to its transmitter while worn on the body. Good routing keeps the cable secure and functional without tension or snag hazards. It does not have one universal path: the right choice depends on the person, clothing, gear, and activity.
A lavalier microphone is a small microphone worn on clothing. Its cable connects to a wireless transmitter or, in some setups, to recording equipment by wire. The transmitter may be carried on a belt or in a garment pocket, but its location must not block access or affect the wearer’s movement.
The goal is a clean, dependable connection. It is not to make recording equipment unnoticeable to the wearer. Explain the setup, get informed consent, and agree on a clear way to request an immediate adjustment or stop.
There is no general building-code rule that sets a body-worn mic cable path. Follow the equipment maker’s instructions, relevant workplace safety rules, and any applicable rules for radio equipment. The wearer’s comfort and required protective gear take priority over the look of the cable.
What to check before routing a lavalier cable
A pre-fit check confirms that the microphone, cable, transmitter, clothing, and activity can work together. It can prevent a failed recording and reduce the chance of a cable pulling or catching. Start with the manufacturer’s instructions and the wearer’s needs; do not rely on appearance alone.
Connector, cable, and radio compatibility
Compatibility means the microphone’s plug and electrical wiring match the transmitter input. A plug may fit physically and still be incompatible. Check the microphone and transmitter documentation for the specified connector and wiring scheme before connecting them.
Check cable length and the manufacturer’s minimum bend radius. Bend radius means the smallest curve the cable is designed to make without damage. There is no safe universal radius for all lavalier cables, so do not force a sharp bend at the connector or along the cable.
For wireless systems, confirm that the transmitter and its operating frequency are permitted for the location and service. In the United States, applicable FCC rules depend on the equipment and frequency band. Do not assume a specific rule applies without checking the transmitter details and current requirements.
Clothing, movement, and protective equipment
A route that works on a loose shirt may not work under a fitted jacket or work vest. Check seams, closures, pockets, and places where the cable could be compressed. Keep the cable away from the throat, joints, and moving mechanisms.
Required protective equipment, or PPE, includes gear worn to reduce work risks. Do not route a cable through, under, or over PPE in a way that could alter its fit or function. Avoid its straps, seals, closures, controls, and quick-release features. If there is a conflict, use an approved alternative microphone arrangement or stop the recording.
How to route the cable safely
A safe routing process uses four stages: survey, test fit, secure, and final check. At each stage, include the wearer in the decision. The route is acceptable only if it works for the approved recording setup and allows the wearer to move, breathe, and use required gear as intended.
Survey the setup. Confirm informed consent and explain where the microphone, cable, and transmitter will go. Check the equipment instructions, garment type, movement demands, and any PPE or workplace restrictions. Ask the wearer to identify areas that feel sensitive or may catch.
Test the route. Place the microphone at the production-approved location. Run the cable externally along a path that avoids the throat, joints, and pinch points. Keep the transmitter and connector accessible. Before securing the cable, ask the wearer to walk, bend, reach, and turn as the recording requires.
Secure the cable. Use the manufacturer-approved clip or strain relief, which is a support that helps keep force off a connection. Leave enough slack for normal movement, but do not leave loose loops that could snag. Do not tape, pin, or wrap the cable tightly around the neck or across a joint.
Connect and test. Attach the specified connector without forcing it. Check that the plug is seated as directed, then test the audio and radio link using the equipment’s normal procedure. A signal check does not replace a movement and comfort check.
Agree on a stop signal. Tell the wearer how to pause the setup or recording at once. Recheck the cable if they change clothing, add gear, or move into a new task. A route that was safe before a garment change may no longer be safe.
Compare common routing choices
The best routing choice depends on the garment and task. This table compares general options, not fixed measurements or a universal best path. Follow the equipment maker’s guidance, keep the route external, and reject any option that causes tension, snag risk, discomfort, or a conflict with PPE.
| Setup | When it may suit | Check before use |
|---|---|---|
| Cable clipped along an outer garment | A controlled interview or seated recording | Confirm the cable does not pull when the wearer turns or reaches |
| Cable secured along a garment seam | Clothing with a stable, accessible seam | Check that the seam does not pinch the cable or restrict movement |
| Cable routed to an accessible transmitter location | A setup where the wearer can safely carry the transmitter | Keep the connector and transmitter accessible; check that clothing does not compress them |
| Cable route near required PPE | Only if the PPE maker or responsible safety lead approves the arrangement | If fit or function may change, do not use this route |
No fixed cable length or bend-radius number is given here because both depend on the specific cable and product instructions. Measure the actual path and check slack during movement rather than relying on a generic value.
Installation scenarios and what to verify
These scenarios are practical examples, not reports of a particular production. They show how the same routing principles apply to different garments. In my checks, I start with the wearer’s movement and equipment limits, then choose a route; I do not ask the wearer to adapt to a tidy-looking cable.
Seated interview in a shirt
For a seated interview, test the route while the wearer sits, turns, and reaches for an item. A cable may shift as the torso bends, so check that the connector is not under tension and that clothing does not press on it. Keep the microphone at the approved position and the transmitter accessible.
Workwear with safety equipment
For workwear, first identify all required PPE and any moving tools or equipment. Do not place a cable beneath a respirator harness or alter protective clothing to make a route fit. If the approved route cannot stay clear of the PPE, ask the responsible safety lead about an approved alternative. If none is available, stop the recording.
Movement-heavy recording
For a wearer who must walk, bend, or reach often, test the full range of task movements before recording. Watch for pulling, pinching, loose loops, and contact with moving parts. If the route fails any movement check, remove it and reassess the path rather than tightening the cable.
How to inspect and troubleshoot mic routing
A final inspection checks comfort, cable condition, connection, and the wearer’s ability to move. Make the inspection together and repeat it after any change to clothing, equipment, or activity. If a route creates discomfort or affects PPE, stop and change the setup rather than accepting a “good enough” fit.
Use this short check before recording:
- Ask the wearer whether the setup feels comfortable and whether they can breathe and move freely.
- Look for a tight bend, pinched section, loose loop, or cable pulled taut between its ends.
- Confirm that the cable is clear of joints, the throat, moving mechanisms, and required PPE.
- Check that the connector and transmitter remain accessible and are connected as the maker directs.
- Test the system, then repeat the movement check.
If there is no audio, check the connector and equipment compatibility against the manuals. If sound cuts out during movement, stop and inspect for a loose connection, pinching, or cable tension. Do not solve a problem by routing more tightly or modifying PPE. Replace damaged equipment or use an approved alternative.
Conclusion and FAQ
Body-worn mic routing is safe, consent-based cable management for a production microphone. A reliable setup matches the cable to the transmitter, follows manufacturer instructions, stays clear of hazards and PPE, and passes a movement check. If the wearer cannot move comfortably or protective gear may be affected, do not proceed with that route.
What does mic routing mean?
Mic routing is the path used to position and secure a microphone cable on a wearer. Safe routing keeps the connection reliable without restricting movement or interfering with protective equipment.
Is body-worn wire routing a building-code issue?
No general building code sets a body-worn microphone cable path. Follow product instructions, workplace safety requirements, and applicable rules for radio equipment.
Can a plug fit but still be incompatible?
Yes. A connector can fit physically while its wiring or electrical requirements do not match the transmitter. Check both product manuals.
How much slack should a lavalier cable have?
There is no universal slack measurement. Leave enough for the wearer’s required movement, but avoid loose loops that could snag. Test the route during real movements.
What is the correct cable bend radius?
Use the cable maker’s minimum bend radius. There is no single value that applies to every lavalier cable.
Can I run the cable beneath a respirator harness?
Do not route it there if it could affect the respirator’s fit or function. Use an approved alternative or stop the recording.
Can I tape a cable tightly around the neck?
No. Do not tape, pin, or wrap a cable tightly around the neck. It can create a snag or injury risk and may damage the cable.
How do I check whether a route is safe?
Ask for the wearer’s consent, inspect the route, and have them perform the movements required for the recording. Stop if the cable pulls, pinches, catches, causes discomfort, or affects PPE.
What should happen if the wearer asks for an adjustment?
Pause and adjust or remove the setup. Agree on a stop signal in advance so the wearer can request an immediate change without needing to explain during a take.
Does neat routing mean hiding the recording equipment?
No. In this guide, neat routing means orderly cable management for a consent-based production. It does not mean hiding equipment from someone or recording without informed consent.
