3. Lighting Tools and Equipment

Lighting plays a pivotal role in setting the mood and enhancing visual elements. AV Technicians must be familiar with different types of lighting equipment.

Stage Lights

• Spotlights: Focused beams used to highlight performers or speakers.
• Wash Lights: Provide wide, even lighting across the stage or venue.
• PAR Cans: Versatile lights used for stage lighting or ambiance.

Intelligent Lighting (Moving Heads)

These programmable lights can change position, color, and effects, offering dynamic visual enhancements.

Lighting Consoles

Lighting consoles control various lighting fixtures and create preprogrammed sequences or effects.

• DMX Controllers: The standard for controlling stage lighting systems.
• Advanced Consoles: Devices like MA Lighting’s GrandMA, used in professional productions.

LED Strips and Accent Lights

Used for creating subtle ambiance or highlighting architectural features in venues.

Fog Machines and Special Effects

• Foggers: Add atmosphere and enhance the effect of stage lights.
• Haze Machines: Produce a fine mist that enhances lighting beams without obscuring visibility.
• Strobes and Lasers: Create high-energy effects for concerts or parties.

4. Networking and IT Tools

In the digital era, AV systems increasingly rely on IT and networking tools for seamless integration.

Network Switches

Network switches are used to connect multiple devices, especially in IP-based systems like Dante (audio networking) or NDI (video networking).

Wireless Access Points

Wireless connectivity enables remote operation of AV systems and supports live-streaming setups.

Routers and Extenders

Ensure stable internet connections, especially for hybrid or virtual events requiring live streaming.

Media Servers

Media servers store and deliver large files such as videos, graphics, or soundtracks used during events.
