The educational system has seen much advancement in recent years. One of the ways by which schools have improved is the delivery of multimedia services to its students. Knowledge is nowadays imparted not only through lectures, but also through the use of various mediums like audio-visual aids and also interactive tools like computers and the Internet.
Among the biggest concerns of schools is how to keep its audio visual equipment up to date. Not only does a school need to have adequate equipment in the auditorium, theater and computer laboratory, each classroom should also have its own tools that can aid in learning. Here are a few things that schools should consider when choosing audio visual equipment.
The classroom. For the classroom, the most common audio visual equipment needed would be an overhead or slide projector. This lets a teacher show prepared slides to students using transparencies, the images of which are projected onto a screen. This might not be enough, though. Advanced projectors can scan opaque material like a page on a book or a picture. Also, teachers might want to show websites or PowerPoint presentations, so an LCD or DLP projector would also be useful. For viewing of films, documentaries and other recorded shows, a television set with a DVD and VCR player would be useful.
For the classroom, schools should choose equipment that are compact and durable. LCD projectors have bulbs with a lifespan of several thousand hours. In this regard, systems that use LED such as digital light projectors (DLPs) might be more appropriate. Because of limited classroom sizes, LCD or LED television sets should be preferred over CRT sets. These might be more expensive, but are generally more durable and can save money in the long run.
The auditorium. Since this is a bigger space than the usual classroom setting, more sophisticated equipment would be needed here. You will most likely require a higher-resolution LCD or DLP projector, which can display crisp videos and images onto screens 60 inches or larger measured diagonally. Most projectors that can support high definition projection should also support analog and digital video input (as with most projectors, even lower-quality ones), so as to support playback of television or DVD videos.
School auditoriums also need additional equipment like a sound system and an adequate lighting system. For this purpose, it’s better to go for amplifiers, mixers, speakers and microphones meant for use in a stage setting.
Because a school will be requiring equipment in bulk, money might be a big consideration. The advantage of schools and other educational institutions, though, is that educational discounts often apply, aside from bulk discounts. Choose a manufacturer or supplier that can provide a packaged solution for your audio-visual needs. Not only will you be able to save with discounts, you will also have an easier time dealing with the supplier for any after-sales support inquiries.
Education is an important aspect of society, and educators and students need the best tools for sharing of knowledge and learning, given resources available. Therefore, choosing audio visual equipment for school needs often requires a balance of features, durability and price.
