Professional conference presentations rely on quality audio-visual setup. Whether you're a first-time presenter or experienced speaker, understanding AV equipment helps you deliver polished presentations and troubleshoot common issues.
Projection and Display
Projectors
Key specifications to understand:
- Lumens: Brightness measurement. Standard meeting rooms need 3000-4000 lumens; large conference venues need 5000+ lumens
- Resolution: Higher is clearer. Look for 1080p (Full HD) minimum, 4K for detailed graphics
- Contrast ratio: Affects image depth and readability in lit rooms
- Throw distance: Distance from projector to screen—affects image size
Screens
Screen options for different settings:
- Fixed screens: Permanent installation, best image quality
- Motorised screens: Retract when not in use, professional appearance
- Tripod screens: Portable, lower cost, suitable for smaller rooms
- Rear projection: Projector behind screen—presenter doesn't block image
Screen Sizing
General guidelines for readability:
- Furthest viewer should be no more than 8x screen height away
- Closest viewer should be at least 2x screen height away
- For 100 people in rows, minimum 3m wide screen recommended
- Multiple screens for very large audiences
Large Format Displays (TVs)
Alternative to projection for smaller meetings:
- 65-85" displays suit 10-30 person meetings
- Brighter and sharper than projection in lit rooms
- No warm-up time required
- Built-in speakers often sufficient for small groups
Audio Equipment
Microphone Types
Lapel/Lavalier Microphones
- Clips to clothing, hands-free
- Ideal for presenters who move around
- Requires wireless transmitter/receiver
- Tip: Clip to centre chest, avoid rustling fabrics
Headset Microphones
- Worn over ear, mic near mouth
- Consistent audio regardless of head movement
- Preferred for active presenters
- Less visible than handheld options
Handheld Microphones
- Traditional speaking tool
- Good for Q&A and panel discussions
- Easy to pass between speakers
- Tip: Hold 15-20cm from mouth, consistent distance
Lectern/Gooseneck Microphones
- Fixed to lectern or podium
- Presenter stays in one position
- Adjust height for each speaker
- Good for formal presentations
Audience Microphones
- For Q&A sessions
- Roving wireless handhelds
- Standing microphone in aisle
- Ceiling-mounted array microphones
Speaker Systems
- PA (Public Address): Voice amplification for large rooms
- Foldback monitors: Speakers facing presenter so they can hear themselves
- Subwoofers: Add bass for video/music content
- Distributed speakers: Multiple smaller speakers for even coverage
Connections and Cables
Video Connections
Know what your laptop has and what the venue provides:
- HDMI: Most common, carries video and audio
- USB-C/Thunderbolt: Modern laptops, may need adapter
- VGA: Older standard, video only (separate audio cable needed)
- DisplayPort: High quality, less common in venues
Essential Adapters
Bring your own to avoid compatibility issues:
- USB-C to HDMI adapter
- USB-C to VGA adapter (for older venues)
- Mini DisplayPort to HDMI
- HDMI extender/repeater for long cable runs
Wireless Presentation Systems
- ClickShare, Barco, Airtame systems
- No cables needed—connect via app or dongle
- Ask venue what system is available
- Test before your session
Presentation Best Practices
Before Your Presentation
- Arrive early to test equipment (30-60 minutes minimum)
- Connect laptop and verify display works
- Test microphone—speak and walk around
- Check audio plays from laptop through speakers
- Locate room controls (lights, blinds, AV)
- Know who to contact for technical support
Slide Design for Venues
- Use 16:9 aspect ratio (matches most screens)
- Large, readable fonts (minimum 24pt for body text)
- High contrast colours (dark text on light, or vice versa)
- Avoid red/green combinations (colour blindness)
- Limit text—use visually compelling slides
- Test videos play correctly (embed, don't link)
During Your Presentation
- Stand to one side—don't block the screen
- Use a presentation remote/clicker
- Face the audience, glance at screen briefly
- Project voice even with microphone
- Have backup of presentation on USB drive
Common Issues and Solutions
Display Not Working
- Check cable connections at both ends
- Try laptop display settings (extend/duplicate)
- Restart laptop if signal not detected
- Try alternate cable or adapter
- Check projector input source is correct
Audio Problems
- No sound: Check laptop volume and output settings
- Feedback/squeal: Lower microphone volume, increase distance from speakers
- Echo: May be from online participants hearing themselves
- Microphone cuts out: Check wireless battery, signal interference
Video Playback Issues
- Embed videos in presentation rather than streaming
- Have videos downloaded locally as backup
- Test video audio plays through venue speakers
- Check video codec compatibility
