Mattison HunterAV Integration, Uncategorized

Whether you’re updating a conference room, planning a campus-wide technology refresh, or managing AV across government or corporate facilities in Phoenix or Salt Lake City, understanding key audiovisual terms can make the entire process smoother.

At Technology Providers, Inc., we believe clear communication is the foundation of successful AV integration — so we created this simple glossary to help you navigate the essentials.

Below are 20 common AV terms you’ll encounter during design, installation, or upgrades.

1. AV Integration

The process of combining audio, video, control systems, and network components into one seamless, functional solution.

2. Control System

A centralized interface — often a touch panel or tablet — that allows users to control AV components like displays, audio levels, sources, and lighting.

3. DSP (Digital Signal Processor)

A device that processes audio signals to improve clarity, remove background noise, and balance sound throughout a room.

4. Video Wall

A large multi-display system made up of tiled screens (LCD or LED) that functions as one cohesive display.

5. LED Display

A bright, energy-efficient display technology ideal for large spaces, lobbies, command centers, and outdoor signage.

6. LCD Display

A standard flat-panel display used in conference rooms, classrooms, and meeting spaces.

7. Projection System

A setup that uses a projector and screen to display content — commonly used in lecture halls, training rooms, and auditoriums.

8. HDMI

A type of cable that transfers high-definition audio and video from a device (like a laptop) to a display.

9. BYOD (Bring Your Own Device)

A collaboration model where users can connect their own laptop, phone, or tablet to the room’s AV system.

10. Unified Communications (UC)

A suite of communication tools — such as Zoom, Teams, or Webex — integrated into a single platform.

11. Hybrid Meeting Room

A space equipped with AV technology that supports both in-person and remote participants.

12. Sound Masking

An audio system that emits unobtrusive background sound to reduce distractions and improve privacy.

13. Acoustics

How sound behaves in a space — influenced by walls, ceilings, flooring, and materials. Proper acoustics improve clarity and reduce echo.

14. Amplifier

A device that boosts audio signals so they can power speakers.

15. Matrix Switcher

A device that sends different audio/video sources to multiple displays or rooms.

16. Source Device

Any device providing content to your AV system — laptops, media players, computers, cameras, or signage players.

17. PTZ Camera

A camera that can Pan, Tilt, and Zoom — often used for hybrid meetings or live streaming.

18. Latency

The delay between when an audio/video signal is sent and when it’s received. Lower latency = smoother performance.

19. Signal Extender

A device that increases the distance an AV signal can travel without losing quality — useful for large buildings or campuses.

20. Rack System

A centralized enclosure that houses all major AV equipment such as processors, switchers, codecs, and amplifiers.

Why Understanding These Terms Matters

Knowing the essentials helps you:

  • Communicate more clearly with your AV partner
  • Make informed purchasing decisions
  • Troubleshoot small issues quickly
  • Understand the long-term impact of AV upgrades
  • Plan for future scalability

Whether you manage AV systems for a corporate office in SLC, a university in Phoenix, or a government facility, this glossary will help you stay confident and informed in every stage of the project.
