Discovering The Uses Of DMX Merger Devices

By Casandra Newton


Stage directors and lighting professionals today typically use the standard for communications named DMX512. This is used to control the lighting and lighting effects system on a stage and is used mainly as a way to automate and computerize a task which was once done all by hand. Being controlled through a DMX Merger, the standard covers characteristics which are electric, data format, connector types, and data protocol.

DMX512 has quickly become the chosen and often singular method for connecting lighting controllers and dimmers, and is also more technologically advanced to control devices like fog machines and moving lights. DMX512is short for Digital Multiplex with 512 pieces of information, however, it is almost always referred to by its shorter name. The standard was created in the 1980s and had some revisions in the 1990s.

The standard provides 512 channel controls for each data input. Often a way to merge standards together is needed in order to get the full control that is desired for lighting programs and equipment. The most well known of merging solution is the DMX merge controller, which is designed to connect two DMX512 sources together to result in one sing output.

The DMX Merger units operate on a120-240 volt power supply, which is included with the purchase of the unit. The unit is a single rack entity and features DMX512 connectors on both the front and rear panels. A big plus with the DMX512 standard is that even with future updates, all existing equipment with continue to work under any new revisions.

Lighting programs and techniques are used in the vast majority of stage productions, including the opera, dance, performance arts, and theater. There are many different lighting elements and pieces of equipment used in just a single performance, more than most people could imagine. Lighting technicians are the people who work behind the scenes to program and control the lighting of a stage performance, they are the unsung heroes of many different elements.

A lighting technicians work is a massive part of most productions, whether the audience realized it or not. Lighting during a production adds a huge amount of drama, depth, and enhancements. The lighting plan can be as complex as an entire light show with special effects and timers, or it can be as simple as one spot light shining down on a character.

Functions for stage lighting are varied and based on the type of production, the equipment being used, and the amount of time and money willing to be spent. Among others, these functions include time of day, projection, selective visibility, intensity and color, and direction, all are used together to create the lighting program.

Projection lighting is used to add to a piece of scenery, project elements onto a blank scene, or be the scenery itself, with the assistance of a DMX Merger. Focus lighting is when certain lighting element are used to direct the audience's attention either to or away from something on the stage. Intensity and color are used because colors, such as red, can evoke emotion and add different feelings and effects to a scene or element on stage.
