Which Projector Is Meant For Me?

  • » The larger the screen, the brighter the projector required.

  • » Rear projection requires a bit more brightness to penetrate the images through    the screen.

  • » HD/ ULTRA HD/ 3D displays require specific projectors that show true HD    images.

Meeting Room Necessities?

  • » Make sure the room is the appropriate size for your audience, keeping in  mind that the AV (i.e. screen,projectors, tech table, etc.) can take up to  approximately 15 % of the room.

  • » Ceiling height largely affects the size of the screen you can fit into the meeting  room. Your audience size determines your screen size, which dictates the optimal ceiling height. Ceiling height, minus five feet, is the approximate size of the largest screen you can fit in a room.

  • » Check for the power sources available in the room, and check if temporary additional power sources are available. Is there a charge for electrical usage? How much? Wall power isn’t always enough

  • » Pillars and chandeliers affect sightlines, which means either less people can be optimally positioned in the room or more displays will  need to be strategically placed

  • » Shape of the room can also be a concern. Square is the most favourable shape to work with in regards to AV  positioning.

  • » Some rooms have a remote control for lighting. It’s a good idea to find out if  there is a cost for it and what the procedure is to make use of it.

  • » Keep in mind that hard surfaces, such as glass, concrete floors and large open ceilings, will reflect sound which can lead to feedback. Equipment selection and placement are important to combat any challenges faced when setting up the AV.

  • » Another consideration should be noise management of the space. Air walls and draping can help to control any unwanted noise from outside the meeting space.

  • » If your conference is multi-day event, check if you have access to the room on a 24-hour basis.

  • » Use the screens that do not pass through the sunlight (high power / high gain) as it will not give a clear display to the viewer.




» Equipments Required For Meeting / Conference/ Events / Classroom

» Audio-Visual Equipment required for the meeting room, conference, event or classroom would be:

» Overhead projector/ Short Throw/ Ultra Short throw projector / HD/ 3D  projector

» Projection stands

» Remote control for projectors

» Screens – Matt / Map type / High gain / High power

» Video equipment: DVD, teleconferencing

» Microphones

» Computer/ Laptop

» Mouse

» Auxiliary equipment:

» Laser pointers, flip charts

» Lighting

» Speakers / Loudspeakers / Amplifiers

Which Screen-Size Should I Use?

  • » For the nearest viewer, one-and-half times the height of the screen should be the minimum viewing distance, with two times being optimal.

  • » For the farthest viewer, eight times the screen height should be the maximum viewing distance, with six times being optimal. (This is based  on a standard Power Point presentation or video playback being the  primary source material)

  • » Detailed illustrations: If highly-detailed graphics and images are  being displayed - for example, Excel spread-sheets, AutoCAD drawings and HD video, then the maximum viewing distance should be  reduced.

  • Viewing distance = four times to six times the screen height for the  farthest viewer to clearly see the text.

  • » 45 degree rule: For viewing angles, the maximum recommended field of view in the horizontal plane is 45 degrees each side of the screen, with 30 degrees on each side of The Screen Being Optimal

Which Sound System Would Suit Me?

House V/S. Independent Sound
  • » The quality of the sound varies with the quality of the system. Therefore, the first thing to do is to test the system and then see if reinforcement is required.

  • » Amplifiers, Speakers and Bass would enable to amplify the sound but it would be as per the dimensions of the room.

  • » When there are multiple wireless microphones (usually more than two or three at one time).

  • » When there is music being played back, requiring more dynamics – house systems don’t normally have much bass or low end.



How Many Microphones Can I Use?

» There is no concrete figure that is required. If you have a good quality of        sound system, it would support multiple microphones.
