Q

Great trussing for pre-rigging lighting and rolling it in.

A

GT truss, most commonly referring to Tyler GT Truss, is a type of aluminum truss designed for the event production industry, particularly for lighting rigs. It’s known for its versatility, strength, and ease of use. Here are some key features of GT truss:

Pre-rigging capabilities: The profile of the truss allows lighting fixtures to be mounted directly onto it before arriving at the venue, eliminating the need for bulky cases and saving time and space during setup.
Lightweight and strong: Made from high-quality 6005A-T6 aluminum, GT truss is strong enough to handle heavy loads while remaining lightweight for easy transport and handling.
Modular design: GT truss comes in various standard lengths (5’, 8’, and 10’) and can be easily connected together using spigots and other hardware to create trusses of various sizes and shapes.

Q
A

mega claws in the context of securing audio visual gear in live event production. Here’s what I can tell you:

Function:

A mega claw is a heavy-duty clamp used to securely mount lighting fixtures, speakers, projectors, and other audio visual equipment on trussing or other support structures.
Features:

Typically made of steel or aluminum for strength and durability.
Designed to grip a wide range of pipe diameters, usually from 1.5” to 2” but can vary depending on the model.
Equipped with a large, easy-to-turn screw mechanism for tight and secure fastening.
Some models have swiveling capabilities for adjusting the angle of the equipment.
Available in various sizes and capacities to accommodate different load weights.
Benefits:

Provides a safe and reliable way to mount heavy equipment, preventing accidents and equipment damage.
Simplifies and speeds up equipment setup and tear-down.
Offers flexibility in positioning equipment for optimal sound and lighting effects.
Common Brands:

Vari-Lite
High End Systems
The Light Source
Doughty Engineering
Where to find them:

Audio visual rental companies
Lighting and trussing suppliers
Online retailers specializing in stage equipment
Additional Information:

Mega claws are essential tools for any professional live event production company.
They are also commonly used in theaters, nightclubs, and other venues where audio visual equipment needs to be securely mounted.
When choosing a mega claw, it’s important to consider the weight of the equipment you need to mount, the diameter of the pipe it will be attached to, and the desired level of adjustability.

Q

Art-Net

A

Art-Net is a royalty-free communications protocol for transmitting the DMX512-A lighting control protocol and Remote Device management (RDM) protocol over ETHERNET cable using the User Datagram Protocol (UDP) of the Internet protocol suite.[1] It is used to communicate between “nodes” (e.g., intelligent lighting instruments) and a “server” (a lighting desk or general purpose computer running lighting control software).

Facilities
Art-Net is a simple implementation of DMX512-A protocol over UDP in which lighting control information is conveyed in IP packets, typically on a private local area network such as Ethernet. Supported functions include transmitting and receiving lighting data (e.g., fader levels for individual lights, positions of movable lights); management functions such as detecting nodes, updating node control parameters, and transmitting timecodes; and functions that allow nodes to “subscribe” to “publisher” nodes so that, for example, nodes A and B can subscribe to node C (C will unicast information to A and B).

Q

MPU in lighting is?

A

Main Processing Unit: This is the central unit of a lighting console that handles all processing, calculations, and communication with lighting fixtures. It’s essentially the brain of the console, responsible for interpreting cues, controlling dimmer packs, and sending DMX data to lights.

Q

sACN ?

A
  • sACN (Streaming ACN - architecture for control networks) is a powerful and increasingly popular protocol used in live event lighting for transmitting DMX data over Ethernet networks.

What is sACN?

  • sACN stands for “Streaming ACN,” an open-source networking protocol.

It offers several advantages over traditional DMX:

  • Built upon the Art-Net framework.
  • It transmits DMX data as Ethernet packets, allowing for longer cable runs, greater flexibility, and easier integration with other network devices.
  • Unlike traditional DMX, which is limited to one universe per cable, sACN can transmit multiple universes over a single Ethernet cable.
  • sACN seamlessly integrates with other network devices and protocols, facilitating communication between lighting, audio, video, and other systems.
  • sACN offers built-in error detection and correction mechanisms, leading to more reliable data transmission and fewer technical glitches.
    Adoption of sACN:
  • While traditional DMX remains widely used for smaller or simpler setups, sACN is becoming the preferred choice for complex productions and venues with advanced networks.
