I would like to set up a conference room with audio/video capabilities. I am planning to use a 7.1 A/V receiver for audio and InFocus 5124 LCD projector for video. This would be used for training and presentations as well as watching an occasional ball game or movie.
Ideally, a presenter would be able to use the A/V system for a slide show from a computer (potentially with a sound track) and talk over it with a wireless microphone. However, most receivers only allow a single input source to be selected. I have not been able to find an A/V receiver that would let me mix a microphone with the 7.1 sound system and watch a slide show from a computer video input. Do you have any suggestions?
