That's so cool! I hope that by the time you start college you are all ready to go. Do they have a loop system in most of the lecture halls?
No loop system - my understanding is that t those are much more common in Commonwealth nations than the US, for whatever reason (you're an Aussie, right?)
But I use an FM system, so I get a similar effect. And a few of the larger lecture halls have had the professor's microphone system outfitted with an FM transmitter/receiver that I can plug my system into, which simplifies things. Although they did make the mistake in a few lecture halls of installing infrared-based systems rather than radio (nothing wrong with IR in the right situation, but the lecture halls in questions have students sitting around tables, and not always facing in the same direction - oops).
