The PROVANTAGE Handbook / Conference audio
Clear conference speech is a complete communication chain: talker, microphone, signal path, loudspeakers, room, listener and operator.
Weakness at any point can make a technically functioning system difficult to understand. The design target is intelligibility and even coverage, with enough headroom for real presenters and live programme changes.
The speech chain
SIX LINKS.
ONE SPOKEN
MESSAGE.
Talker
Brief speakers on distance, orientation and handling. A microphone cannot restore words never captured clearly.
Microphone
Choose and position it for the person, movement, clothing, stage layout and available gain before feedback.
Signal path
Set clean gain, processing and routing while preserving headroom and a monitored fallback.
Loudspeakers
Place and align coverage so useful level reaches the audience evenly without feeding excessive energy back to microphones.
Room
Account for reverberation, reflections, HVAC, audience noise and surfaces that reduce intelligibility.
Operator
Mix actively, listen across the room, follow the programme and intervene through an agreed communication path.
Microphone format is a production decision
MATCH THE
PERSON AND
THE STAGE.
Handheld
Close placement can support strong intelligibility, but technique and handovers must be managed.
Lavalier
Visually discreet and familiar for presenters; placement, clothing noise and feedback margin need attention.
Headworn
Consistent mouth-to-microphone distance can improve level and clarity where the format is acceptable.
Lectern
Works for a controlled speaking position; height, aiming, duplicate capsules and speaker movement matter.
Table or boundary
Useful in some panels and meetings, but room pickup and participant distance must be evaluated.
The volume trap
LOUDER
IS NOT ALWAYS
CLEARER.
Raising level cannot remove reverberation, correct poor coverage or compensate indefinitely for a distant microphone. It may reduce comfort and feedback margin. Improve capture, placement, coverage and room behaviour before treating level as the answer.
Conference readiness
CHECK THE
REAL PROGRAMME
BEFORE DOORS.
Walk the audience
Listen at front, rear, sides and difficult seats using representative speech.
Soundcheck people
Confirm microphone position, technique, routing and names with actual speakers where possible.
Run the formats
Test lectern, panels, walk-and-talk, audience Q&A, playback and remote contribution.
Control open mics
Plan automixing or active mixing around room noise, feedback margin and conversational flow.
Prepare intervention
Place backup microphones and define who can approach a speaker or change a device.
Protect continuity
Monitor batteries, receivers, signal paths and operator communications throughout the show.
The practical takeaway
DESIGN FOR
THE WORDS.
NOT THE BOXES.
Begin with speakers, programme formats, room geometry and the audience. Equipment selection follows the intelligibility problem rather than leading it.
