 Moving head lights might be operated by many different approaches. The units are hooked up to a lighting board, providing a control data signal. The information transmitted by the it to the moving head lights might be via 3 techniques - Analogue (applied in former times), DMX (the normal control protocol) or Ethernet connection. As soon as it is obtained, the data signal is transmitted into internal ones, that are transmitted to the motors located inside the units. Fixtures using analogue connection are already in the past and are not popular today. The factors for this are many - restrictions on bandwidth, information transfer rates and potential errors - are just a few of them. The normal procedure for controlling moving heads fixtures is the DMX standard, typically using separate twisted pair, shielded cable and 3 or five pin XLR connections at the ends of it. Each single moving head unit is assigned to a specific block of DMX channels (the DMX standard allows control of up to 512 distinct channels). The lighting controller assigns the signal on these channels, and the moving head DMX reacts according to the data signal it receives - this may be values for colour, style, cycle speed or also moving images. All the effects are pre-programmed. Moving heads DMX are a lot more tough to be set up compared to their analogue relatives since each unit has a lot more characteristics to be managed. A normal lighting fixture needs just one channel for operation - intensity of the light. Meanwhile, a moving head DMX may have over twenty. There exist 2 basic solutions that might be seen on the market for controlling the different channels on many moving head lights: lighting boards and DMX software. Though lighting boards are still applied, most individuals prefer the DMX software to organise their shows. Among the primary benefits of the DMX software is the fact that they present a rendered preview of the expected result, so individuals can improvise on their light schemes and patterns and they know what to expect from it, without even coming into the disco or the nightclub before. Another positive aspect is the chance of transforming a computer's USB port to a DMX one. The latest types of moving head lights use RJ-45 for information transfer, due to the fact the Ethernet technology assists for the greater management of a much greater variety and a lot more complex effects. Quite a few of the moving head fixtures have the option for digital projection, and they can form a great conflux of lighting and video images. These new types of heads do not just require intensity, place and focus management, but will require video content management as well. In conclusion, being capable to point moving head lights to different spots in the area or develop energetic patterns in the air is a highly effective weapon in a nightclub if searching for spectacular light shows. Moving head fixtures play a key role for the success of any nightclub, bar or disco.
