Hi, I have been asked to spec. a system for a conference with up to 500 delegates. The conference is to be held next year and as yet they have not finalised the venue yet. Two venues have been shortlisted - a large'ish sports hall and the other an open hall with lots of metal gurders in the roof. Looking at what various companies offer for rental for approx. 500 people, varies. Some offer Bose speakers with amps. etc whereas others give 3 sets of EV's. One company recommended large Mackie cabs. As there is unlikely to be any music apart from some light background music during breaks, what would should I be looking at in terms of amp. power, speakers, mixer etc? The mic requirements are two goose neck microphones for the main speaker and 1/2 for comperes. Which gooseneck mics give the least pop/breath noises? Thanks.
