A sound system of high performance allows the message to be delivered to viewers as needed in any event, either outdoors or indoors.

{Mosimage} many years ago who attended the cinema saw that people were talking about, but never heard his voice, for that reason the players needed more body language and a very good facial expression for the audience to understand what they were representing, but also leaving messages between scenes and the sound of music issued by the piano during projection, they helped create the story in the head assistant; in this period film, silence was the main factor that represented, and the sound was only known in real life.

Later, the film had audio and synchronized sound you rigged up technologically with the image which could be mixed voices, ambient sound, dialogue and music. Thus the films began to fully reflect the sense of cinema and viewers perfectly understood the message of the story.

But the sound is not only used to give life to cinema, bars, clubs, shopping malls, auditoriums and stadiums, among others, the audio makes every space and every place is full of vitality, information and entertainment. However, sometimes the sound used in these spaces or activities is misused and distorted what actually is meant.

It has been imagined being at a concert and not hear the singer's voice? Or being in a hospital and not understand your name when you call? These and more are some of the problems that can have if an audio system is not configured properly installed or who does not have the necessary knowledge and experience.

professional audio

The term professional audio can be used both to talk about the kind of equipment that can be used, or to refer to the application as such of engineering.

Professional audio systems include speakers, microphones, mixing consoles, amplifiers, recording mechanisms, and others, which have qualities and quality far superior to common audio production systems.

Meanwhile, professional audio application relates to professional audio engineering and operations as a radio transmission, audio mastering, consolidating sound like a concert, performances of DJ's, audio sample rate, surround sound or ambient music, which make it more special places and events.

This type of audio, which has special characteristics, can also be defined as high-performance audio, in the words of Francisco Ortiz, designer of systems audio and video of the Colombian company Electroacústica Engineering, is nothing more than a sound system which is designed in order to meet stringent reliability and safety parameters for the application that was designed, such as commercial and industrial sound, sound entertainment, live sound and car audio.

Each thing in its place

The high performance applications may vary according to customer needs, for example, commercial and industrial audio is configured to be used in shopping malls, airports, transport stations, systems called in factories and offices, auditoriums, conference rooms or convention centers. Meanwhile the sound for entertainment is installed according to the characteristics of the places, which may well be bars, clubs, restaurants, nightclubs, theaters, theme parks or multizone systems for home and high-end home theaters. However, it should be noted that the sound is different for live shows such as concerts or outdoor games or in stadiums and much more for cars, for which now are creating high performance teams.

But professional audio systems should have characteristics that make them special and as such give this category of "professional" or "high performance":

• Equipment high mechanical strength.
• Excellent frequency response (fidelity).
• Harnesses and connectors of the highest quality.
• You must have a temperature protection system, as this is the main
amplification enemy.
• Maintaining constant power amplification at high temperatures in
If ventilation fail.
• Sources (microphones, CD, DVD, etc.) must be of good quality and brand to ensure a clean and stable signal, the same as the pre-amplification (consoles, equalizers, processes, etc.).

These features allow high-performance systems achieve its mission, so that as Ortiz says he has assured that the message, event or presentation is performed without a hitch given the quality and safety of components and who install them.

meeting needs

All new creations or inventions have a reason or a need that should be supplemented also happens with professional audio systems, because no one wants their system to fail when you need it most. For many integrators or for the same customers, investing in high performance teams means spending a large sum of money very different from what had been used in a conventional system, but after that the person or the company invests lot of money and time on conventional equipment repair underperforming, it is discovered that would have been much better to have high-performance system from the beginning.

Also to work with this type of audio to be taken into account locations or the type of event you are going to use, it is not the same as the audio for a musical that for a football game, or sound in a open in a closed space.

Significantly, not always, but a system installed in the scenarios have, it is used in the same way, because their use varies depending on the needs of each show. In Colombia for example, you can find professional audio equipment in auditoriums, nightclubs, bars, theaters, conference rooms and home, as described Francisco.

Unlike conventional instruments audio, high-performance systems are not integrated with computers that are not in the same category if what you want is to maintain the quality and reliability of the system. Ortiz says about this does not mean that there are no simple equipment of very high quality and very complex equipment of poor quality. Also it asserts that "integration with video and lighting is very common nowadays for example in video conference rooms, auditoriums, theaters, home theaters, nightclubs and more.

The management of these systems should be performed by a person trained sufficiently in order to achieve maximum performance of equipment. It should also be noted that the professional audio can be controlled in a manner analogous or digital through sensitive screens wired or wireless touch, also through a program installed on a PC and remotely over LAN or Internet.

A step forward

Latin America has always been characterized by receiving the technology later in life than other regions, but in Latin America industry audio and video has achieved remarkable progress, so that many new teams come relatively quickly and new technologies easily incorporated.

Additionally you are creating a culture of high technology primarily aimed at the end client, who has the final word about the reliability of a system, given the benefits that may or may not receive este.Del same way the training and updates are positioning in the region thanks to the activities InfoComm and some companies that have committed to the education of specialists and technicians in the industry.

For Francis the future of this technology is projected to greater integration with computer systems and network. "Today people dedicated to the assembly of these systems, not only should know sound, audio, electronics, but also IP technology and networks in general," he says.

The integration of AV systems for multipurpose rooms being implemented in Latin America. Many convention centers and hotels have systems that allow audio and video to deliver as required by users.
