I attended three graduation in rites in a week and in one of them, I was the guest speaker. It was hard talking to a bunch of graduates with hyperactive tendencies in an open area. Though the sound system was loud enough, it was hard communicating with the person in-charge of the sound and video system. The point persons on stage and off stage did not have headphones so they could hear each other amongst the din of sounds. After the program I asked the stage soundman if they have headphones. He said the school has 2 akg k240 that they use for recording. They never actually thought of using them until I asked!Oh well, next time then.
