Convert line input to mic input camcorder

Please help! I have recently bought a wireless amplifier system that can amplify the sounds of my teacher while she is teaching. However, i also need to video record the lesson down from a distance. The problem is that i am sitted to far away from the speakers and picking up to many stray noises due to the distance. Is it possible for me to connect my camcorder mic to the speaker so that i can record directly from the amplifier system's speakers? My amplifier system is simple: a transmitter hooked on to the belt and a receiver which is the amplifier.
