1) For a small auditorium about 30 meters long, 20 meters wide and 4 to 6 meters tall, equipped with 12 small cheap loudspeakers (6 each side) along the hall, what is THE BEST WATTAGE amplifier for speeches? We have setup two TDA2005 circuits plus one small "workaround" for a preamplifier (actually a weaker amp before the power amp).... but it doesn't seem to deliver good sound. Was it because we needed a piezoelectric microphone? Is it best to be equipped with a real preamplifier?

2) When someone talks over the microphone, and the speakers "distorts" according to some tonal sylabs, what sign is that... bad amplifier, weak speakers or lack of a hardlimiter circuit?

3) Going around the previous problem, what kind of circuit must one have to "control" voice pitches so that one won't "shout" over the mic or not be clearly listened by the crowd (because his voice may be too low).
