AV TECHNOLOGY GUIDE

Audiovisual Technology.

Reliable AV is a signal-flow problem: know where every picture and sound starts, where it goes and what happens if any link fails.

For clients & planners

The overview

Event AV covers sound reinforcement (microphones, mixer, speakers), displays (LED walls, projectors, TVs, confidence monitors), lighting and the signal routing that connects them to cameras, laptops and the stream.

The room decides the gear. Ceiling height, ambient light, audience size and seating shape whether you need an LED wall or a projector, and how many speakers cover the room evenly.

A site visit and a simple drawing (stage plot and signal flow) prevent most show-day problems.

KEY DECISIONS

The choices that shape budget and quality.

QuestionOptionsOur guidance
LED wall or projection?LED is bright, works in daylight and outdoors; projection is economical for dark rooms and very large images.LED for bright rooms, outdoors and camera-heavy events; projection for dark ballrooms on a budget.
Screen sizeRule of thumb: screen height about one-sixth to one-eighth of the distance to the farthest viewer.We size from your floor plan and furthest seat.
MicrophonesHandheld, lavalier, headset, podium gooseneck, or boundary.Headsets for presenters who move; handhelds for Q&A; one spare per type.
SpeakersPoint-source on stands, column arrays, or flown line arrays.Column arrays for clear speech in medium rooms; line arrays for large venues and music.
FOR PRODUCERS & CREW

Technical deep dive.

Specs, settings, standards and current tools. Facts that change are dated and sourced.

LED walls
  • Pixel pitch sets the minimum comfortable viewing distance: roughly 1 m per 1 mm of pitch (a P2.6 wall looks clean from about 2.6 m and beyond).
  • Brightness: 800–1,500 nits indoors, 4,000–6,000 nits in daylight; outdoor-rated cabinets need IP65 front protection.
  • Refresh rate of 3,840 Hz or higher avoids scan lines on camera; set camera shutter to match and test before the show.
  • Processing: feed the wall at its native resolution (for example, 1920 × 1152 for a 16 × 10 ft P2.6 wall) to avoid scaling artifacts.
Projection
  • Brightness in lumens scales with screen size and ambient light; 8,000–10,000 lumens for large screens in partially lit rooms.
  • Throw ratio decides lens and position; rear projection keeps presenters out of the beam.
Video over IP
  • SMPTE ST 2110: uncompressed broadcast standard over managed networks with PTP timing.
  • IPMX: the open ST 2110/NMOS-based standard for pro AV; AIMS certified the first 48 IPMX products from 10 manufacturers at ISE 2026, adding compressed video and HDCP support.
  • NDI 6: low-latency video over standard networks with HDR (PQ/HLG) and 10+ bit color; NDI Bridge links remote sites over the internet. Version 6.3 added remote connection control and sender monitoring.
  • SDI (3G/12G) and HDMI remain the most common point-to-point links; use fiber or SDI for long runs and HDMI only for short ones.
Audio networking and wireless
  • Dante carries many audio channels over one network cable; it now supports ST 2110-30 and AES67 configuration directly in Dante Controller (fall 2025 update) for broadcast interoperability.
  • Wireless microphones: UHF spectrum shrank after the 600 MHz and 700 MHz auctions; coordinate frequencies on site (the 600 MHz duplex gap leaves only a few usable megahertz), and consider 1.4 GHz, 1.9 GHz (DECT) or 2.4 GHz digital systems for dense venues.
  • Gain structure: set mic preamps for healthy level with headroom, ring out feedback with EQ, and keep the mix intelligible first, loud second.
Power and safety
  • Map circuits before load-in: LED walls and amplifiers need dedicated 20 A circuits; use a power distro for large rigs.
  • Rigging is done by qualified riggers to venue rules; ground-stacked LED walls need rated bases and wind bracing outdoors.
  • Cable paths taped or covered; fire exits and aisles kept clear.
PLANNING CHECKLIST

Before the shoot or show.

  • Floor plan with stage, screens, front-of-house and audience
  • Power circuits and distances confirmed with the venue
  • Stage plot and signal flow drawing
  • Microphone list per segment and spares
  • Presenter laptop adapters (HDMI, USB-C) and clickers
  • Frequency coordination for wireless
  • Load-in, setup, rehearsal and strike times agreed with the venue
CLIENT FAQS

Questions we hear most.

What does pixel pitch mean?

The distance between LED pixels in millimeters. Smaller numbers mean sharper images up close. A P2.6 wall looks crisp from a few meters back, ideal for stages and lobbies.

Can an LED wall work outdoors in daylight?

Yes, if it is outdoor-rated (IP65) and bright enough, typically 4,000+ nits. Our 16 × 10 ft P2.6 wall reaches 5,000 nits.

Why do screens flicker on camera?

A mismatch between the camera shutter and the display refresh rate. We use high-refresh LED processing and set camera shutters to match.

Will an LED wall be readable on a sunny Atlanta afternoon?

Ours is rated at 5,000 nits, bright enough for daylight. We still aim it away from the low sun, use high-contrast content and give the processors shade and airflow in summer heat.

Can outdoor AV run in Columbus in March or November?

Yes, with a cold-weather plan: covered cable runs, gear warmed up before doors, spare batteries kept warm, and a rain and wind call made by a set time with the venue.

Can you set up a watch party for a big game?

We can build the screens and sound. Showing a game publicly is a broadcast-rights question, so the venue needs the right commercial viewing license. We handle the AV; you or the venue confirm the license.
