I am looking for a solution to a problem that requires the least amount of equipment. I use a lot of audio in my classroom - from videos, mp3, etc but also students speaking out. The acoustics in the class are awful - many of the students also have very tiny voices, so they cannot be heard. I would like to be able to connect 3 speakers via bluetooth to a sound system - my notebook? - and distribute the speakers throughout the class so that everyone can hear. I also would like to be able to connect at least 3 microphones to the sound system - computer. I will keep one continually and 2 others will be passed around as needed. I have read that some bt speakers can be connected to three sources. Is it possible to connect 3 bt speakers to one source? The only solution I can find for the microphones is to buy a set that has a transmitter with either 2 or 4 microphones connected to it. Is there any way to get around needing the transmitter for the microphone part? I teach in 22 different classrooms each week, so am looking for a way to minimize what I have to carry. BTW, I will be using an ASUS tablet with a quadcore atom cpu.
