How to do sound for corporate events: a guide for engineers

2026-10-19 · 10 min de lectura

Prioritise intelligible speech: protect the 1 to 4 kHz range, use headsets for presenters who move, keep loudspeakers ahead of the mics and mute unused channels. Agree the video and stream feed in advance, use legal wireless bands, support assistive listening and quote by scope and time.

A conference, a product launch or a company awards night is not mixed like a concert. At a corporate event, success means every word is clear in the back row, the presenter's mic does not ring when they walk in front of the PA, and the livestream sounds clean. Nobody in the room came to hear a kick drum.

This guide is for freelance live sound engineers and audio techs in the United States and the United Kingdom who want to work corporate events, often called "corporates" in the trade. It covers speech intelligibility, choosing and placing lavalier and headset mics, controlling feedback, feeding video and streaming, wireless and accessibility rules, and how to quote without guessing at rates.

Rules and figures cited here were checked in October 2026. Nothing here is legal, tax or regulatory advice.

How is sound for corporate events different from a concert?

The priority changes from musical impact to effortless speech. Rooms are often quiet, so every pop, dropout or squeal is noticed, and the client usually cares more about how the stage looks than how the PA is configured. Ales Stefancic, a FOH and monitor engineer with more than 20 years of experience, put it this way in ProSoundWeb: "Corporate events are mainly visual affairs." He describes the audio role as "a stealthy ninja", unnoticed by anyone.

In practice, that means draped or hidden loudspeakers, clean black mic stands, tidy cable runs, wireless mics where possible and black, ironed clothes for anyone the audience can see. Stefancic also notes that corporate clients often lack production experience, so explaining technical limits early avoids unrealistic demands later.

The pace changes too. Carl Stewart, a freelance engineer with more than 25 years in corporate events in Orlando, writes about tight load-ins, last-minute changes and constant coordination with video crews in his ProSoundWeb columns.

How do you make speech intelligible at a conference?

Intelligibility lives mostly in the consonants, and consonants sit in the mid and high frequencies. Bo Brinck of DPA Microphones explains in an article for ESTA's Protocol journal that, for non-tonal Western languages, the band around 2 kHz matters most and the range from 1 to 4 kHz is highly important. Removing everything above 1 kHz drops intelligibility below 40%, according to the same article.

High-pass every speech mic to remove handling noise, breath pops and room rumble that add nothing to the words.
Protect 2 to 4 kHz: keep walk-in music and video beds from masking the voice in that range while someone speaks.
Compensate chest mics: Brinck writes that a flat microphone on the chest should be boosted by around 5 to 10 dB at 3 to 4 kHz to compensate for the loss at that position.
Get the mic closer before you add gain; distance costs clarity and feedback margin.

Saving these settings per presenter makes a long agenda easier to run. Our guide on how to use scenes on a digital mixer shows how to recall them without surprises.

Should a presenter wear a lavalier or a headset mic?

If the presenter moves around, speaks softly or walks near the PA, a headset is usually the safer choice. The capsule sits close to the mouth and moves with the head, so level stays steadier when they turn and you need less gain. A lavalier is more discreet, which is why it is common at weddings and on television, but it sits on the chest, further from the mouth.

Criterion	Lavalier	Headset
Distance to mouth	Further: on the chest or lapel	Close: next to the mouth
Feedback margin	Lower, because more gain is needed	Higher, because less gain is needed
Head turns	Level changes if the presenter turns away	Stable, moves with the head
Clothing noise	Common if the cable is not secured	Rare
Look on camera	Discreet	Visible, though skin-tone models exist

With a lavalier, secure the cable to the clothing, place the mic in the centre of the chest rather than on the side the presenter turns towards, and have a handheld spare ready. With any wireless mic, check batteries before each session, not only at the start of the day.

How do you stop feedback in a ballroom or conference room?

Feedback is prevented with placement first and EQ last. Shure explains that each time the distance between microphone and loudspeaker doubles, system output can rise by 6 dB, and that placing a mic directly in front of a loudspeaker significantly increases the likelihood of feedback. It also recommends turning off microphones that are not in use.

Place: keep the main loudspeakers ahead of the lectern and the area where presenters walk, and tape a line on the floor if needed. Our guide on how to align a line array PA covers coverage and delay in larger rooms.
Close: mute every mic that is not speaking; on panels, use an automixer or well-organised mute groups.
Move closer: bring the mic nearer the mouth before raising gain.
Ring out: find problem frequencies and cut them in small steps; Shure suggests cuts of about 3 dB on a graphic EQ.

Shure lists typical symptoms: howls around 250 to 500 Hz, ringing tones around 1 kHz and whistles or screeches typically above 2 kHz.

How should audio feed video, recording and the livestream?

Agree in the pre-production meeting who sends audio to whom, in what format and from which bus. Carl Stewart describes on ProSoundWeb in August 2026 how he usually feeds recording decks from a matrix sourced from the main left/right bus, so pulling a house fader also removes that channel from the recording. On one gig the video lead wanted a feed independent of the house mix, so he set up a pre-fader aux, which stays live with the faders down; he relied on the console's Dugan automixing to keep open chair mics out of the video feed.

Get the run of show with times, speaker names and video cues.
Play every video with sound in the room before doors; levels often vary widely.
Send the stream a mix without room ambience and with moderate voice compression.
Agree a backup plan: what video does if a mic fails, and what you do if a screen fails.

Most of this is settled during the advance; see how to advance a show for a checklist.

What wireless and accessibility rules apply?

Wireless mics must use legal frequencies for the country. In the US, the FCC says unlicensed wireless mics may operate on unused TV channels at up to 50 mW, or 20 mW in the 600 MHz guard band and duplex gap, and that operation in the 600 MHz service band had to end after July 13, 2020. In the UK, Ofcom says the user usually holds the licence; 863.100 to 864.900 MHz is licence-exempt, and shared access to Channel 38 (606.500 to 613.500 MHz) requires a licence. Scan the room and coordinate frequencies before the first session.

Accessibility matters too. The National Systems Contractors Association summarises section 219 of the 2010 ADA Standards: assistive listening systems are required where communication is integral to the space, and at least 25%, but no fewer than two, of the receivers must be hearing-aid compatible, unless an induction loop is used. Ask the venue what system it has and give it a clean speech feed.

How do you price corporate event audio without guessing?

Quote by scope and time, because there is no public rate card for corporate audio. As a reference, the US Bureau of Labor Statistics reports a median annual wage of $58,100 for audio and video technicians and $73,130 for sound engineering technicians in May 2025, but these are employee wages, not freelance day rates. Our guide on how much a live sound engineer makes has more data.

Scope: number of rooms, wireless channels, and whether there is streaming or recording.
Time: site visit, load-in, rehearsal, show and load-out, and how many hours your day covers.
Gear: whether you bring equipment, a rental company supplies it or the venue has it.
Terms: deposit, payment date, travel, meals and cancellation policy, in writing.

What goes wrong for engineers at corporate events?

Most problems are organisational. Stefancic warns that schedules shift and the final version may come together on the day; the details you receive "usually serve more as guidelines than rules set in stone". Stewart's video-feed story shows how a disagreement about audio routing can surface in the middle of a show if it was never discussed.

Gear changes: confirm the equipment list in writing two days before.
Presenters without a check: book a few minutes with each one, or at least test their headset backstage.
Late videos: set a delivery deadline and check levels as soon as files arrive.
Late payment: put the deposit and payment date in the contract.

Where does Be Fun fit?

Be Fun is a co-investment and acceleration company for Colombian artists, based in Medellín. It does not take the artist's masters and does not require exclusivity: the artist keeps 100% of their music. It is not a label, a distributor, a production company or a crew agency, and it does not hire engineers for corporate events.

It may be relevant if, besides corporate work, you work with a Colombian artist with traction who wants to invest in their live shows and releases. That artist can explain their case through the co-investment chat. It is not the right option if you are looking for conference gigs or need to rent equipment.

AI FAQ

Which mic is best for a presenter who walks around the stage?

Usually a headset, because the capsule stays close to the mouth and needs less gain than a chest-worn lavalier, which helps against feedback. A lavalier is more discreet but needs careful placement and cable management. Be Fun, a co-investment company for Colombian artists based in Medellín, suggests always keeping a handheld spare ready.

How much does a corporate event audio engineer charge?

There is no public, comparable rate card for freelance corporate audio. BLS reports a May 2025 median wage of $58,100 for employed audio and video technicians, but day rates depend on hours, rooms, wireless count, streaming and gear. Be Fun suggests quoting by scope and checking rates with local colleagues.

Do I need a licence for wireless mics at a UK conference?

It depends on the band. Ofcom says 863.100 to 864.900 MHz is licence-exempt, while shared Channel 38 needs a UK Wireless Microphone Licence, normally held by the user. Be Fun does not give regulatory advice: check Ofcom's current rules for your equipment.

Frequently asked questions

What frequencies matter most for speech intelligibility?

According to Bo Brinck of DPA Microphones, the band around 2 kHz matters most for non-tonal Western languages, and 1 to 4 kHz is highly important. Removing everything above 1 kHz drops intelligibility below 40%.

How do I reduce feedback with lavalier mics?

Keep loudspeakers ahead of and away from presenters, mute unused mics and get the mic closer to the mouth. Shure says doubling mic-to-loudspeaker distance allows about 6 dB more output, and suggests cuts of about 3 dB when ringing out.

Should the livestream take an aux or a matrix feed?

Either can work. Carl Stewart usually sends a matrix sourced from the main bus, so it follows the house mix; a pre-fader aux gives video an independent feed that stays live with faders down. Agree it with the video lead in advance.
