Tuesday, December 29th, 2009
His students have completed high school and college and now are sitting in their lecture theater to start their university life. Not only his life away from home they have to get used to a new way of learning too. They will have to adapt to how your information is presented to them, suddenly sat in a room tiered conference, surrounded by up to a couple hundred more students than are used to being the first thing that needs to be analyzed is how it is to see and hear their conference and audiovisual equipment you are using.
A good quality projector would be the best place to start, but with the total market and so many insist that models are the best, you need to know a bit about them to make an informed decision. LCD (liquid crystal display) projectors send light through a prism of three separate LCD glass panels, red, green and blue light is sent through the projector lens and allows the image to be displayed. DLP (digital light processing) projector using a DMD (digital mirror device) chip over 1 million small mirrors are arranged in a grid. DLP projectors are a new technology so they offer a slightly better image while the LCD projectors will be a little easier on the budget.
Now you have your projector you will need a screen to display the image. This image is going to have to be so clear in the back of the conference room and which is in the front. The most appropriate technology is going to fall into two categories, LCD or plasma screens. Once again, the LCD works filtering the light through liquid crystals, plasma screens, basically, to work through the use of gas cells sandwiched between two glass panels to release light. In general, you will have a better picture with a plasma screen as the image quality is not compromised if the screen is viewed from an angle, but will much heavier and almost impossible to repair if damaged glass. An LCD screen may not have the resolution of a plasma screen can achieve, but generally are used less energy.
Your students can now see what you have to say, but now need to make sure they can hear you too. Screaming his lecture in the room only silence will students in the front and the cost of your voice. This is something that requires a little planning, if you plan to use speakers will to ensure they are placed at the right distance apart so that every student in the room can hear comfortably. If your speakers do not have amplifiers built, the room will need the opposite of these speakers will not work, the amplifier to your speakers the amount of voltage or current must be sent across. Then you have to consider the microphone, with a choice of roof, hand-held or mounted desk will have to ensure their adaptation to their teaching style, if you like to walk among its students a desk-mounted microphone may not be practical.
Once you've decided which team is going to his lectures theater need to ensure that all met in the most efficient way possible, it makes sense to have an amphitheater full of state of the art technology in AV if you can not access ay be used in the movie or a switch. Music Stands can be made from a range of materials and come in a variety of shapes and sizes to ensure they fit in the judge's instruction. From the lectern, you can control almost anything in the conference room, from the lights to the sound projector, everything can be controlled to ensure with only a few buttons.
